gdbsupport: change path_join parameter to array_view<const char *>
When a GDB built with -D_GLIBCXX_DEBUG=1 reads a binary with a single
character name, we hit this assertion failure:

The problem is this line in path_join:
gdb_assert (strlen (path) == 0 || !IS_ABSOLUTE_PATH (path));
... where `path` is "x". IS_ABSOLUTE_PATH eventually calls
HAS_DRIVE_SPEC_1:
#define HAS_DRIVE_SPEC_1(dos_based, f) \
((f)[0] && ((f)[1] == ':') && (dos_based))
This macro accesses indices 0 and 1 of the input string. However, `f`
is a string_view of length 1, so it's incorrect to try to access index
1. We know that the string_view's underlying object is a null-terminated
string, so in practice there's no harm. But as far as the string_view
is concerned, index 1 is considered out of bounds.
This patch makes the easy fix, that is to change the path_join parameter
from a vector of to a vector of `const char *`. Another solution would
be to introduce a non-standard gdb::cstring_view class, which would be a
view over a null-terminated string. With that class, it would be
correct to access index 1, it would yield the NUL character. If there
is interest in having this class (it has been mentioned a few times in
the past) I can do it and use it here.
This was found by running tests such as gdb.ada/arrayidx.exp, which
produce 1-char long filenames, so adding a new test is not necessary.

gdb: add "id" fields to identify symtabs and subfiles
Printing macros defined in the main source file doesn't work reliably
using various toolchains, especially when DWARF 5 is used. For example,
using the binaries produced by either of these commands:
$ gcc --version
gcc (GCC) 11.2.0
$ ld --version
GNU ld (GNU Binutils) 2.38
$ gcc test.c -g3 -gdwarf-5
$ clang --version
clang version 13.0.1
$ clang test.c -gdwarf-5 -fdebug-macro
I get:
$ ./gdb -nx -q --data-directory=data-directory a.out
(gdb) start
Temporary breakpoint 1 at 0x111d: file test.c, line 6.
Starting program: /home/simark/build/binutils-gdb-one-target/gdb/a.out
Temporary breakpoint 1, main () at test.c:6
6 return ZERO;
(gdb) p ZERO
No symbol "ZERO" in current context.
When starting to investigate this (taking the gcc-compiled binary as an
example), we see that GDB fails to look up the appropriate macro scope
when evaluating the expression. While stopped in
macro_lookup_inclusion:
(top-gdb) p name
$1 = 0x62100011a980 "test.c"
(top-gdb) p source.filename
$2 = 0x62100011a9a0 "/home/simark/build/binutils-gdb-one-target/gdb/test.c"
`source` is the macro_source_file that we would expect GDB to find.
`name` comes from the symtab::filename field of the symtab we are
stopped in. GDB doesn't find the appropriate macro_source_file because
the name of the macro_source_file doesn't match exactly the name of the
symtab.
The name of the main symtab comes from the compilation unit's
DW_AT_name, passed to the buildsym_compunit's constructor:

gdb/dwarf: pass a file_entry to line_header::file_file_name
In the following patch, there will be some callers of file_file_name that will already have access to the file_entry object for which they want the file name. It would be inefficient to have them pass an index, only for line_header::file_file_name to re-lookup the same file_entry object. Change line_header::file_file_name to accept a file_entry object reference, instead of an index to look up. I think this change makes sense in any case. Callers that have an index can first obtain a file_entry using line_header::file_name_at or line_header::file_names. When passing a file_entry object, we can assume that the file_entry's index is valid, unlike when passing an index. So, push the special case about an invalid index to the sole current caller of file_file_name, macro_start_file. I think that error belongs there anyway, since it specifically talks about "bad file number in macro information". This requires recording the file index in the file_entry structure, so add that.

gdb/dwarf: pass compilation directory to line header
The following patch changes line_header::file_file_name to prepend the compilation directory to the file name, if needed. For that, the line header needs to know about the compilation directory. Prepare for that by adding a constructor that takes it as a parameter, and passing the value down everywhere needed. Add a second constructor for the special case of building a line_header for doing a hash table lookup, since that case doesn't require a compilation directory value.

gdb/dwarf: remove line_header::total_length field
This doesn' have to be a field, it can simply be a local variable in dwarf_decode_line_header. Name the local variable "unit_length", since that's what the field in called in DWARF 4 and 5. It's always easier to follow the code with the standard on the side when we use the same terminology. Change-Id: I3ad1022afd9410b193ea11b9b5437686c1e4e633 |

gdbsupport: add path_join function
In this review [1], Eli pointed out that we should be careful when
concatenating file names to avoid duplicated slashes. On Windows, a
double slash at the beginning of a file path has a special meaning. So
naively concatenating "/" and "foo/bar" would give "//foo/bar", which
would not give the desired results. We already have a few spots doing:
if (first_path ends with a slash)
path = first_path + second_path
else
path = first_path + slash + second_path
In general, I think it's nice to avoid superfluous slashes in file
paths, since they might end up visible to the user and look a bit
unprofessional.
Introduce the path_join function that can be used to join multiple path
components together (along with unit tests).
I initially wanted to make it possible to join two absolute paths, to
support the use case of prepending a sysroot path to a target file path,
or the prepending the debug-file-directory to a target file path. But
the code in solib_find_1 shows that it is more complex than this anyway
(for example, when the right hand side is a Windows path with a drive
letter). So I don't think we need to support that case in path_join.
That also keeps the implementation simpler.
Change a few spots to use path_join to show how it can be used. I
believe that all the spots I changed are guarded by some checks that
ensure the right hand side operand is not an absolute path.
Regression-tested on Ubuntu 18.04. Built-tested on Windows, and I also
ran the new unit-test there.

[gdb/symtab] Support .debug_line with DW_FORM_line_strp
I noticed a new gcc option -gdwarf64 and tried it out (using gcc 11.2.1).
With a test-case hello.c:
...
int
main (void)
{
printf ("hello\n");
return 0;
}
...
compiled like this:
...
$ gcc -g -gdwarf64 ~/hello.c
...
I ran into:
...
$ gdb -q -batch a.out
DW_FORM_line_strp pointing outside of .debug_line_str section \
[in module a.out]
...
Debugging gdb revealed that the string offset is:
...
(gdb) up
objfile=0x182ab70, str_offset=1378684502312,
form_name=0xeae9b5 "DW_FORM_line_strp")
at src/gdb/dwarf2/section.c:208
208 error (_("%s pointing outside of %s section [in module %s]"),
(gdb) p /x str_offset
$1 = 0x14100000128
(gdb)
...
which is read when parsing a .debug_line entry at 0x1e0.
Looking with readelf at the 0x1e0 entry, we have:
...
The Directory Table (offset 0x202, lines 2, columns 1):
Entry Name
0 (indirect line string, offset: 0x128): /data/gdb_versions/devel
1 (indirect line string, offset: 0x141): /home/vries
...
which in a hexdump looks like:
...
0x00000200 1f022801 00004101 00000201 1f020f02
...
What happens is the following:
- readelf interprets the DW_FORM_line_strp reference to .debug_line_str as
a 4 byte value, and sees entries 0x00000128 and 0x00000141.
- gdb instead interprets it as an 8 byte value, and sees as first entry
0x0000014100000128, which is too big so it bails out.
AFAIU, gdb is wrong. It assumes DW_FORM_line_strp is 8 bytes on the basis
that the corresponding CU is 64-bit DWARF. However, the .debug_line
contribution has it's own initial_length field, and encodes there that it's
32-bit DWARF.
Fix this by using the correct offset size for DW_FORM_line_strp references
in .debug_line.
Note: the described test-case does trigger this complaint (both with and
without this patch):
...
$ gdb -q -batch -iex "set complaints 10" a.out
During symbol reading: intermixed 32-bit and 64-bit DWARF sections
...
The reason that the CU has 64-bit dwarf is because -gdwarf64 was passed to
gcc. The reason that the .debug_line entry has 32-bit dwarf is because that's
what gas generates. Perhaps this is complaint-worthy, but I don't think it
is wrong.
Tested on x86_64-linux, using native and target board dwarf64.exp.

Fix file-name handling regression with DWARF index
When run with the gdb-index or debug-names target boards, dup-psym.exp fails. This came up for me because my new DWARF scanner reuses this part of the existing index code, and so it registers as a regression. This is PR symtab/25834. Looking into this, I found that the DWARF index code here is fairly different from the psymtab code. I don't think there's a deep reason for this, and in fact, it seemed to me that the index code could simply mimic what the psymtab code already does. That is what this patch implements. The DW_AT_name and DW_AT_comp_dir are now stored in the quick file names table. This may require allocating a quick file names table even when DW_AT_stmt_list does not exist. Then, the functions that work with this data are changed to use find_source_or_rewrite, just as the psymbol code does. Finally, line_header::file_full_name is removed, as it is no longer needed. Currently, the index maintains a hash table of "quick file names". The hash table uses a deletion function to free the "real name" components when necessary. There's also a second such function to implement the forget_cached_source_info method. This bug fix patch will create a quick file name object even when there is no DW_AT_stmt_list, meaning that the object won't be entered in the hash table. So, this patch changes the memory management approach so that the entries are cleared when the per-BFD object is destroyed. (A dwarf2_per_cu_data destructor is not introduced, because we have been avoiding adding a vtable to that class.) Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=25834 |

gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

gdb: rename dwarf2_per_objfile variables/fields to per_objfile
While doing the psymtab-sharing patchset, I avoided renaming variables unnecessarily to avoid adding noise to patches, but I'd like to do it now. Basically, we have these dwarf2 per-something structures: - dwarf2_per_objfile - dwarf2_per_bfd - dwarf2_per_cu_data I named the instances of dwarf2_per_bfd `per_bfd` and most of instances of dwarf2_per_cu_data are called `per_cu`. Most pre-existing instances of dwarf2_per_objfile are named `dwarf2_per_objfile`. For consistency with the other type, I'd like to rename them to just `per_objfile`. The `dwarf2_` prefix is superfluous, since it's already clear we are in dwarf2 code. It also helps reducing the line wrapping by saving 7 precious columns. gdb/ChangeLog: * dwarf2/comp-unit.c, dwarf2/comp-unit.h, dwarf2/index-cache.c, dwarf2/index-cache.h, dwarf2/index-write.c, dwarf2/index-write.h, dwarf2/line-header.c, dwarf2/line-header.h, dwarf2/macro.c, dwarf2/macro.h, dwarf2/read.c, dwarf2/read.h: Rename struct dwarf2_per_objfile variables and fields from `dwarf2_per_objfile` to just `per_objfile` throughout.

Move more code to line-header.c
This moves some more code out of read.c and into line-header.c. dwarf_decode_line_header is split into two -- the part remaining in read.c handles interfacing to the dwarf2_cu; while the part in line-header.c (more or less) purely handles the actual decoding. gdb/ChangeLog 2020-03-26 Tom Tromey <tom@tromey.com> * dwarf2/line-header.h (dwarf_decode_line_header): Declare. * dwarf2/read.c (dwarf2_statement_list_fits_in_line_number_section_complaint): Move to line-header.c. (read_checked_initial_length_and_offset, read_formatted_entries): Likewise. (dwarf_decode_line_header): Split into two. * dwarf2/line-header.c (dwarf2_statement_list_fits_in_line_number_section_complaint): Move from read.c. (read_checked_initial_length_and_offset, read_formatted_entries): Likewise. (dwarf_decode_line_header): New function, split from read.c. |

Make some line_header methods const
This changes a few line_header methods to be const. In some cases, a const overload is added. gdb/ChangeLog 2020-03-26 Tom Tromey <tom@tromey.com> * dwarf2/line-header.h (struct line_header) <is_valid_file_index, file_names_size, file_full_name, file_file_name>: Use const. <file_name_at, file_names>: Add const overload. * dwarf2/line-header.c (line_header::file_file_name) (line_header::file_full_name): Update. |

Move DWARF line_header to new file
This moves the line_header class to a pair of new files, making dwarf2/read.c somewhat smaller. 2020-02-08 Tom Tromey <tom@tromey.com> * dwarf2/read.h (dwarf_line_debug): Declare. * Makefile.in (COMMON_SFILES): Add dwarf2/line-header.c. * dwarf2/read.c: Move line_header code to new files. (dwarf_line_debug): No longer static. * dwarf2/line-header.c: New file. * dwarf2/line-header.h: New file. Change-Id: I8d9d8a2398b4e888e20cc5dd68d041c28b5a06e3 |
