Stop assuming no-debug-info variables have type int
An earlier commit made GDB no longer assume no-debug-info functions
return int. This commit gives the same treatment to variables.
Currently, you can end misled by GDB over output like this:
(gdb) p var
$1 = -1
(gdb) p /x var
$2 = 0xffffffff
until you realize that GDB is assuming that the variable is an "int",
because:
(gdb) ptype var
type = <data variable, no debug info>
You may try to fix it by casting, but that doesn't really help:
(gdb) p /x (unsigned long long) var
$3 = 0xffffffffffffffff # incorrect
^^
That's incorrect output, because the variable was defined like this:
uint64_t var = 0x7fffffffffffffff;
^^
What happened is that with the cast, GDB did an int -> 'unsigned long
long' conversion instead of reinterpreting the variable as the cast-to
type. To get at the variable properly you have to reinterpret the
variable's address manually instead, with either:
(gdb) p /x *(unsigned long long *) &var
$4 = 0x7fffffffffffffff
(gdb) p /x {unsigned long long} &var
$5 = 0x7fffffffffffffff
After this commit GDB does it for you. This is what you'll get
instead:
(gdb) p var
'var' has unknown type; cast it to its declared type
(gdb) p /x (unsigned long long) var
$1 = 0x7fffffffffffffff
As in the functions patch, the "compile" machinery doesn't currently
have the cast-to type handy, so it continues assuming no-debug
variables have int type, though now at least it warns.
The change to gdb.cp/m-static.exp deserves an explanation:
- gdb_test "print 'gnu_obj_1::method()::sintvar'" "\\$\[0-9\]+ = 4" \
+ gdb_test "print (int) 'gnu_obj_1::method()::sintvar'" "\\$\[0-9\]+ = 4" \
That's printing the "sintvar" function local static of the
"gnu_obj_1::method()" method.
The problem with that test is that that "'S::method()::static_var'"
syntax doesn't really work in C++ as you'd expect. The way to make it
work correctly currently is to quote the method part, not the whole
expression, like:
(gdb) print 'gnu_obj_1::method()'::sintvar
If you wrap the whole expression in quotes, like in m-static.exp, what
really happens is that the parser considers the whole string as a
symbol name, but there's no debug symbol with that name. However,
local statics have linkage and are given a mangled name that demangles
to the same string as the full expression, so that's what GDB prints.
After this commit, and without the cast, the print in m-static.exp
would error out saying that the variable has unknown type:
(gdb) p 'gnu_obj_1::method()::sintvar'
'gnu_obj_1::method()::sintvar' has unknown type; cast it to its declared type
TBC, if currently (even before this series) you try to print any
function local static variable of type other than int, you'll get
bogus results. You can see that with m-static.cc as is, even.
Printing the "svar" local, which is a boolean (1 byte) still prints as
"int" (4 bytes):
(gdb) p 'gnu_obj_1::method()::svar'
$1 = 1
(gdb) ptype 'gnu_obj_1::method()::svar'
type = <data variable, no debug info>
This probably prints some random bogus value on big endian machines.
If 'svar' was of some aggregate type (etc.) we'd still print it as
int, so the problem would have been more obvious... After this
commit, you'll get instead:
(gdb) p 'gnu_obj_1::method()::svar'
'gnu_obj_1::method()::svar' has unknown type; cast it to its declared type
... so at least GDB is no longer misleading. Making GDB find the real
local static debug symbol is the subject of the following patches. In
the end, it'll all "Just Work".

Stop assuming no-debug-info functions return int
The fact that GDB defaults to assuming that functions return int, when
it has no debug info for the function has been a recurring source of
user confusion. Recently this came up on the errno pretty printer
discussions. Shortly after, it came up again on IRC, with someone
wondering why does getenv() in GDB return a negative int:
(gdb) p getenv("PATH")
$1 = -6185
This question (with s/getenv/random-other-C-runtime-function) is a FAQ
on IRC.
The reason for the above is:
(gdb) p getenv
$2 = {<text variable, no debug info>} 0x7ffff7751d80 <getenv>
(gdb) ptype getenv
type = int ()
... which means that GDB truncated the 64-bit pointer that is actually
returned from getent to 32-bit, and then sign-extended it:
(gdb) p /x -6185
$6 = 0xffffe7d7
The workaround is to cast the function to the right type, like:
(gdb) p ((char *(*) (const char *)) getenv) ("PATH")
$3 = 0x7fffffffe7d7 "/usr/local/bin:/"...
IMO, we should do better than this.
I see the "assume-int" issue the same way I see printing bogus values
for optimized-out variables instead of "<optimized out>" -- I'd much
rather that the debugger tells me "I don't know" and tells me how to
fix it than showing me bogus misleading results, making me go around
tilting at windmills.
If GDB prints a signed integer when you're expecting a pointer or
aggregate, you at least have some sense that something is off, but
consider the case of the function actually returning a 64-bit integer.
For example, compile this without debug info:
unsigned long long
function ()
{
return 0x7fffffffffffffff;
}
Currently, with pristine GDB, you get:
(gdb) p function ()
$1 = -1 # incorrect
(gdb) p /x function ()
$2 = 0xffffffff # incorrect
maybe after spending a few hours debugging you suspect something is
wrong with that -1, and do:
(gdb) ptype function
type = int ()
and maybe, just maybe, you realize that the function actually returns
unsigned long long. And you try to fix it with:
(gdb) p /x (unsigned long long) function ()
$3 = 0xffffffffffffffff # incorrect
... which still produces the wrong result, because GDB simply applied
int to unsigned long long conversion. Meaning, it sign-extended the
integer that it extracted from the return of the function, to 64-bits.
and then maybe, after asking around on IRC, you realize you have to
cast the function to a pointer of the right type, and call that. It
won't be easy, but after a few missteps, you'll get to it:
..... (gdb) p /x ((unsigned long long(*) ()) function) ()
$666 = 0x7fffffffffffffff # finally! :-)
So to improve on the user experience, this patch does the following
(interrelated) things:
- makes no-debug-info functions no longer default to "int" as return
type. Instead, they're left with NULL/"<unknown return type>"
return type.
(gdb) ptype getenv
type = <unknown return type> ()
- makes calling a function with unknown return type an error.
(gdb) p getenv ("PATH")
'getenv' has unknown return type; cast the call to its declared return type
- and then to make it easier to call the function, makes it possible
to _only_ cast the return of the function to the right type,
instead of having to cast the function to a function pointer:
(gdb) p (char *) getenv ("PATH") # now Just Works
$3 = 0x7fffffffe7d7 "/usr/local/bin:/"...
(gdb) p ((char *(*) (const char *)) getenv) ("PATH") # continues working
$4 = 0x7fffffffe7d7 "/usr/local/bin:/"...
I.e., it makes GDB default the function's return type to the type
of the cast, and the function's parameters to the type of the
arguments passed down.
After this patch, here's what you'll get for the "unsigned long long"
example above:
(gdb) p function ()
'function' has unknown return type; cast the call to its declared return type
(gdb) p /x (unsigned long long) function ()
$4 = 0x7fffffffffffffff # correct!
Note that while with "print" GDB shows the name of the function that
has the problem:
(gdb) p getenv ("PATH")
'getenv' has unknown return type; cast the call to its declared return type
which can by handy in more complicated expressions, "ptype" does not:
(gdb) ptype getenv ("PATH")
function has unknown return type; cast the call to its declared return type
This will be fixed in the next patch.

compile: Add 'set compile-gcc'

compile-loc2c: Fix uninitialized variable error
Compiling with clang gives this warning/error:
/home/emaisin/src/binutils-gdb/gdb/compile/compile-loc2c.c:731:6: error: variable 'uoffset' is uninitialized when used here [-Werror,-Wuninitialized]
uoffset += dwarf2_per_cu_text_offset (per_cu);

uint64_t uoffset, reg;
^
= 0
I am really not sure if what this patch does is good, but it is my best
guess. DW_OP_addr means that there's an constant address provided by
the DWARF bytecode that should be pushed on the stack. That address is
considered skipped by the "op_ptr += addr_size", but it is never read.
uoffset is indeed read just after, without having been assigned first.
So I think the intent is to read the address, it was just omitted.
gdb/ChangeLog:

Introduce command_line_up
This introduces command_line_up, a unique_ptr for command_line objects, and changes many places to use it. This removes a number of cleanups. Command lines are funny in that sometimes they are reference counted. Once there is more C++-ification of some of the users, perhaps all of these can be changed to use shared_ptr instead. gdb/ChangeLog 2017-04-12 Tom Tromey <tom@tromey.com> * tracepoint.c (actions_command): Update. * python/python.c (python_command, python_interactive_command): Update. * mi/mi-cmd-break.c (mi_cmd_break_commands): Update. * guile/guile.c (guile_command): Update. * defs.h (read_command_lines, read_command_lines_1): Return command_line_up.

Convert lvalue reference type check to general reference type check
In almost all contexts (except for overload resolution rules and expression semantics), lvalue and rvalue references are equivalent. That means that in all but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE check and, for switch statements, add a case label for a rvalue reference type next to a case label for an lvalue reference type.

Use gdb::function_view in iterate_over_symtabs & co
I wanted to pass a lambda to iterate_over_symtabs (see following patch), so I converted it to function_view, and then the rest is cascaded from that. This gets rid of a bunch of single-use callback functions and corresponding manually managed callback capture types (add_partial_datum, search_symbols_data, etc.) in favor of letting the compiler generate them for us by using lambdas with a capture. In a couple cases, it was more natural to convert the existing function callbacks to function objects (i.e., operator(), e.g., decode_compound_collector). gdb/ChangeLog: 2017-02-23 Pedro Alves <palves@redhat.com> * ada-lang.c: Include "common/function-view.h".

Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy
This patch starts from the desire to eliminate
make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file &
friends a real C++ class hierarchy, and switches temporary
ui_file-like objects to stack-based allocation.
- mem_fileopen -> string_file
mem_fileopen is replaced with a new string_file class that is treated
as a value class created on the stack. This alone eliminates most
make_cleanup_ui_file_delete calls, and, simplifies code a whole lot
(diffstat shows around 1k loc dropped.)
string_file's internal buffer is a std::string, thus the "string" in
the name. This simplifies the implementation much, compared to
mem_fileopen, which managed growing its internal buffer manually.
- ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone
The new string_file class has a string() method that provides direct
writable access to the internal std::string buffer. This replaced
ui_file_as_string, which forced a copy of the same data the stream had
inside. With direct access via a writable reference, we can instead
move the string out of the string_stream, avoiding deep string
copying.
Related, ui_file_xstrdup calls are replaced with xstrdup'ping the
stream's string, and ui_file_obsavestring is replaced by
obstack_copy0.
With all those out of the way, getting rid of the weird ui_file_put
mechanism was possible.
- New ui_file::printf, ui_file::puts, etc. methods
These simplify / clarify client code. I considered splitting
client-code changes, like these, e.g.:
- stb = mem_fileopen ();
- fprintf_unfiltered (stb, "%s%s%s",
- _("The valid values are:\n"),
- regdesc,
- _("The default is \"std\"."));
+ string_file stb;
+ stb.printf ("%s%s%s",
+ _("The valid values are:\n"),
+ regdesc,
+ _("The default is \"std\"."));
In two steps, with the first step leaving fprintf_unfiltered (etc.)
calls in place, and only afterwards do a pass to change all those to
call stb.printf etc.. I didn't do that split, because (when I tried),
it turned out to be pointless make-work: the first pass would have to
touch the fprintf_unfiltered line anyway, to replace "stb" with
"&stb".
- gdb_fopen replaced with stack-based objects
This avoids the need for cleanups or unique_ptr's. I.e., this:
struct ui_file *file = gdb_fopen (filename, "w");
if (filename == NULL)
perror_with_name (filename);
cleanups = make_cleanup_ui_file_delete (file);
// use file.
do_cleanups (cleanups);
is replaced with this:
stdio_file file;
if (!file.open (filename, "w"))
perror_with_name (filename);
// use file.
- odd contorsions in null_file_write / null_file_fputs around when to
call to_fputs / to_write eliminated.
- Global null_stream object
A few places that were allocating a ui_file in order to print to
"nowhere" are adjusted to instead refer to a new 'null_stream' global
stream.
- TUI's tui_sfileopen eliminated. TUI's ui_file much simplified
The TUI's ui_file was serving a dual purpose. It supported being used
as string buffer, and supported being backed by a stdio FILE. The
string buffer part is gone, replaced by using of string_file. The
'FILE *' support is now much simplified, by making the TUI's ui_file
inherit from stdio_file.

Use class to manage BFD reference counts
This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts. Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct. The existing code here is hard for me to follow. One goal of this sort of automated reference counting, though, is to make it more difficult to make logic errors; so hopefully the code is clear now. 2017-01-10 Tom Tromey <tom@tromey.com> * windows-tdep.c (windows_xfer_shared_library): Update. * windows-nat.c (windows_make_so): Update. * utils.h (make_cleanup_bfd_unref): Remove. * utils.c (do_bfd_close_cleanup, make_cleanup_bfd_unref): Remove. * symfile.h (symfile_bfd_open) (find_separate_debug_file_in_section): Return gdb_bfd_ref_ptr. * symfile.c (read_symbols, symbol_file_add) (separate_debug_file_exists): Update.

Remove make_cleanup_htab_delete
This removes make_cleanup_htab_delete in favor of destructors, building on an earlier patch that added the htab_up typedef. Testing revealed that more cleanup-removal work was needed in dwarf2loc.c, so this version of the patch changes code there to use unordered_set and vector, removing some more cleanups. 2017-01-10 Tom Tromey <tom@tromey.com> * utils.h (make_cleanup_htab_delete): Don't declare. * utils.c (do_htab_delete_cleanup, make_cleanup_htab_delete): Remove. * linespec.c (decode_compound_collector): Add constructor, destructor.

Use ui_file_as_string in gdb/compile/
Using ui_file_as_string would imply changing a few prototypes to pass around source and object file names as std::string. Instead of that, wrap those two in a new class. This ends up eliminating a small wrinkle: get_new_file_names and compile_object_load have swapped parameters. The former takes "source, objfile", while the latter takes "objfile, source". gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * c-lang.h (c_compute_program): Now returns std::string. * compile/compile-internal.h (class compile_file_names): New class. * compile/compile-object-load.c (compile_object_load): Replace object_file and source_file parameters with a compile_file_names parameter.

Use RAII to save and restore scalars
This patch replaces many (but not all) uses of make_cleanup_restore_integer with a simple RAII-based template class. It also removes the similar restore_execution_direction cleanup in favor of this new class. Subsequent patches will replace other similar cleanups with this class. The class is typically instantiated using make_scoped_restore. This allows for template argument deduction. 2016-10-21 Tom Tromey <tom@tromey.com> * common/scoped_restore.h: New file. * utils.h: Include scoped_restore.h. * top.c (execute_command_to_string): Use scoped_restore. * python/python.c (python_interactive_command): Use scoped_restore.

Handle DW_OP_form_tls_address
Currently gdb supports DW_OP_GNU_push_tls_address, but not DW_OP_form_tls_address. I think it would be better if the toolchain as a whole moved to using the standard opcode, and the prerequisite to this is getting gdb to recognize it. GCC can sometimes emit DW_OP_form_tls_address for emultls targets. As far as I know, nobody has ever tried this with gdb (since it wouldn't work at all). I don't think there's a major drawback to using a single opcode for all targets, because computing the location of a thread-local is already target specific. This is PR gdb/11616. I don't know how to write a test case for this; though it's worth noting that there aren't explicit tests for DW_OP_GNU_push_tls_address either -- and if I change GCC, these paths will be tested to the same extent they are now. 2016-09-02 Tom Tromey <tom@tromey.com> PR gdb/11616: * dwarf2read.c (decode_locdesc): Handle DW_OP_form_tls_address. * dwarf2loc.c (dwarf2_compile_expr_to_ax): Handle DW_OP_form_tls_address.

Make the interpreters be per UI
Make each UI have its own interpreter list, top level interpreter, current interpreter, etc. The "interpreter_async" global is not really specific to an struct interp (it crosses interpreter-exec ...), so I moved it to "struct ui" directly, while the other globals were left hidden in interps.c, opaque to the rest of GDB. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * breakpoint.c (bpstat_do_actions_1): Access the current UI's async field instead of the interpreter_async global. * cli/cli-script.c (execute_user_command, while_command) (if_command, script_from_file): Likewise. * compile/compile.c: Include top.h instead of interps.h.

Return void from linker callbacks
The ldmain.c implementation of these linker callback functions always return true, so any code handling a false return is dead. What's more, some of the bfd backends abort if ever a false return is seen, and there seems to be some confusion in gdb's compile-object-load.c. The return value was never meant to be "oh yes, a multiple_definition error occurred", but rather "out of memory or other catastrophic failure".

Type-safe wrapper for enum flags
This patch fixes C++ build errors like this:
/home/pedro/gdb/mygit/cxx-convertion/src/gdb/linux-tdep.c:1126:35: error: invalid conversion from ‘int’ to ‘filterflags’ [-fpermissive]
| COREFILTER_HUGETLB_PRIVATE);
^
This is a case of enums used as bit flags. Unlike "regular" enums,
these values are supposed to be or'ed together. However, in C++, the
type of "(ENUM1 | ENUM2)" is int, and you then can't assign an int to
an enum variable without a cast. That means that this:
enum foo_flags flags = 0;
if (...)
flags |= FOO_FLAG1;
if (...)
flags |= FOO_FLAG2;
... would have to be written as:
enum foo_flags flags = (enum foo_flags) 0;
if (...)
flags = (enum foo_flags) (flags | FOO_FLAG1);
if (...)
flags = (enum foo_flags) (flags | FOO_FLAG2);
which is ... ugly. Alternatively, we'd have to use an int for the
variable's type, which isn't ideal either.
This patch instead adds an "enum flags" class. "enum flags" are
exactly the enums where the values are bits that are meant to be ORed
together.
This allows writing code like the below, while with raw enums this
would fail to compile without casts to enum type at the assignments to
'f':
enum some_flag
{
flag_val1 = 1 << 1,
flag_val2 = 1 << 2,
flag_val3 = 1 << 3,
flag_val4 = 1 << 4,
};
DEF_ENUM_FLAGS_TYPE(enum some_flag, some_flags)
some_flags f = flag_val1 | flag_val2;
f |= flag_val3;
It's also possible to assign literal zero to an enum flags variable
(meaning, no flags), dispensing either adding an awkward explicit "no
value" value to the enumeration or the cast to assignments from 0.
For example:
some_flags f = 0;
f |= flag_val3 | flag_val4;
Note that literal integers other than zero do fail to compile:
some_flags f = 1; // error
C is still supported -- DEF_ENUM_FLAGS_TYPE is just a typedef in that
case.

Add some more casts (1/2)
Note: I needed to split this patch in two, otherwise it's too big for the mailing list. This patch adds explicit casts to situations where a void pointer is assigned to a pointer to the "real" type. Building in C++ mode requires those assignments to use an explicit cast. This includes, for example: - callback arguments (cleanups, comparison functions, ...) - data attached to some object (objfile, program space, etc) in the form of a void pointer - "user data" passed to some function This patch comes from the commit "(mostly) auto-generated patch to insert casts needed for C++", taken from Pedro's C++ branch. Only files built on x86 with --enable-targets=all are modified, so the native files for other arches will need to be dealt with separately. I built-tested this with --enable-targets=all and reg-tested. To my surprise, a test case (selftest.exp) had to be adjusted. Here's the ChangeLog entry. Again, this was relatively quick to make despite the length, thanks to David Malcom's script, although I don't believe it's very useful information in that particular case... gdb/ChangeLog: * aarch64-tdep.c (aarch64_make_prologue_cache): Add cast(s).

Add casts to memory allocation related calls
Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

Replace some xmalloc-family functions with XNEW-family ones
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

DWARF: handle non-local references in nested functions
GDB's current behavior when dealing with non-local references in the
context of nested fuctions is approximative:
- code using valops.c:value_of_variable read the first available stack
frame that holds the corresponding variable (whereas there can be
multiple candidates for this);
- code directly relying on read_var_value will instead read non-local
variables in frames where they are not even defined.
This change adds the necessary context to symbol reads (to get the block
they belong to) and to blocks (the static link property, if any) so that
GDB can make the proper decisions when dealing with non-local varibale
references.

Add casts for legitimate integer to enum conversions
This patch is mostly extracted from Pedro's C++ branch. It adds explicit casts from integer to enum types, where it is really the intention to do so. This could be because we are ... * iterating on enum values (we need to iterate on an equivalent integer) * converting from a value read from bytes (dwarf attribute, agent expression opcode) to the equivalent enum * reading the equivalent integer value from another language (Python/Guile) An exception to that is the casts in regcache.c. It seems to me like struct regcache's register_status field could be a pointer to an array of enum register_status. Doing so would waste a bit of memory (4 bytes used by the enum vs 1 byte used by the current signed char, for each register). If we switch to C++11 one day, we can define the underlying type of an enum type, so we could have the best of both worlds. gdb/ChangeLog: * arm-tdep.c (set_fp_model_sfunc): Add cast from integer to enum.

Replace the block_found global with explicit data-flow

Remove CHECK_TYPEDEF, use check_typedef instead
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit
annoying. It makes unclear the fact that the "type" variables gets
overwritten. It has actually bitten me a few times. I think the
following, explicit form, is better.
type = check_typedef (type);
This patches changes all instances of CHECK_TYPEDEF for an equivalent
call to check_typedef. The bulk of the change was done with this sed:
sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c
The ChangeLog was generated using David Malcom's generate_changelog.py.
I manually fixed those places where it gets the wrong function name,
hopefully all of them.
The patch was built-tested, and I ran a few smoke tests.

compile: Warn for old GCC on cv-qualified self-reference
GDB could: compile code struct_object.selffield = &struct_object ./compile/compile-c-types.c:83: internal-error: insert_type: Assertion `add == NULL || add->gcc_type == gcc_type' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) FAIL: gdb.compile/compile.exp: compile code struct_object.selffield = &struct_object (GDB internal error) The bug was not in GDB but in the GCC part interfacing with GDB.

compile: Use also inferior munmap
Currently inferior memory is allocated by inferior mmap() but it is never deallocated; despite the injected objfile incl. its symbols is freed. This was intentional so that one can do for example: inferior: char *str = "foo"; GDB: (gdb) compile code str = "bar"; I believe later patches will be needed to introduce full control over keeping vs. discarding the injected module as being discussed in: compile: objfiles lifetime UI https://sourceware.org/ml/gdb/2015-04/msg00051.html Message-ID: <20150429135735.GA16974@host1.jankratochvil.net> https://sourceware.org/ml/gdb/2015-05/msg00007.html As decided by Phil it is better not to leak inferior pages as users can workaround the issue above for example by: (gdb) compile code str = strdup ("bar"); I have checked that in fact gdb/doc/ (written by Phil) already expects the injected code will be unmapped so that does not need to be changed: compile code int ff = 5; p = &ff; In this example, @code{p} would point to @code{ff} when the @code{compile} command is executing the source code provided to it. However, as variables in the (example) program persist with their assigned values, the variable @code{p} would point to an invalid location when the command exists. gdb/ChangeLog 2015-04-28 Jan Kratochvil <jan.kratochvil@redhat.com> * arch-utils.c (default_infcall_munmap): New. * arch-utils.h (default_infcall_munmap): New declaration. * compile/compile-object-load.c (struct munmap_list, munmap_list_add) (munmap_list_free, munmap_listp_free_cleanup): New.

compile: New 'compile print'
It is planned the existing GDB command 'print' will be able to evaluate its expressions using the compiler. There will be some option to choose between the existing GDB evaluation and the compiler evaluation. But as an intermediate step this patch provides the expression printing feature as a new command. I can imagine it could be also called 'maintenance compile print' as in the future one should be able to use its functionality by the normal 'print' command. There was a discussion with Eli about the command name: https://sourceware.org/ml/gdb-patches/2015-03/msg00880.html As there were no other comments yet I haven't renamed it yet, before there is some confirmation about settlement on the final name.

Code cleanup: compile: func_addr -> func_sym
Currently the code fetches _gdb_expr address/types at multiple places, guessing its parameters at multiple places etc. Fetch it once, verify it has expected type and then rely on it. While the patch tries to clean up the code it is still horrible due to the missing C++ sub-classing. gdb/ChangeLog 2015-05-16 Jan Kratochvil <jan.kratochvil@redhat.com> * compile/compile-object-load.c (get_regs_type): Add parameter func_sym.

compile: Use -Wall, not -w
For a reason unknown to me GDB was using -w instead of -Wall for 'compile code'.
The problem is later patch for 'compile printf' really needs some warnings to
be able to catch for example missing format string parameters:
(gdb) compile printf "%d\n"
GCC does not seem to be able to cancel -w (there is nothing like -no-w).
Besides that I think even 'compile code' can benefit from -Wall.
That #ifndef change in print_one_macro() is needed otherwise we get
macro-redefinition warnings for the GCC built-in macros (as -w is no
longer in effect). For example, without the #ifndef/#endif one gets:
compile -r -- void _gdb_expr(){int i = 5;}^M
/tmp/gdbobj-xpU1yB/out4.c:4:0: warning: "__FILE__" redefined [-Wbuiltin-macro-redefined]^M
/tmp/gdbobj-xpU1yB/out4.c:5:0: warning: "__LINE__" redefined^M
...
It makes more sense to pick the inferior's version of the macros, hence
#ifndef instead of #undef.
That new testsuite XFAIL is there as if one changes the struct definition to be
compliant with cv-qualifiers (to prevent the warnings):
struct struct_type {
- struct struct_type *selffield;
+ volatile struct struct_type *selffield;
only then GCC/GDB will hit the crash, described in that GDB PR 18202.
