Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.
Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet. I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

This changes compile_cplus_convert_enum to use "false".
Note that this variable is never modified, which seems like an error.
I filed PR compile/24473 for this.

"false".
The include sorter can't handle multi-line comments on the same line
as a #include. This patch removes the only such comment.
In general I think these sorts of comments do not provide much value:
more often than not, I find that the comment is obsolete in one way or
another, and so the include sorter removes them in most cases.

2019-01-22 Tom Tromey <tom@tromey.com>
* compile/compile-cplus-types.c: Remove a comment by #include.
This patch changes cp-support.c:cp_func_name to return a
'gdb::unique_xmalloc_ptr<char>' instead of a 'char *'. This allows a
cleanup to be removed from valops.c:find_overload_match.
gdb/ChangeLog:
* compile/compile-cplus-types.c
(compile_cplus_instance::decl_name): Handle changes to
cp_func_name.
* cp-support.c (cp_func_name): Update header comment, update
return type.
* cp-support.h (cp_func_name): Update return type in declaration.
* valops.c (find_overload_match): Move temp_func local to top
level of function and change its type. Use temp_func to hold and
delete temporary string obtained from cp_func_name.
This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Patch
d82b3862f12 ("compile: Remove non-const reference parameters")
introduced a regression in compile/compile-cplus-types.c. The new_scope
variable in compile_cplus_instance::enter_scope is used after it was
std::moved. This patch fixes it by referring to the back of the vector
where it was moved instead.
gdb/ChangeLog:
* compile/compile-cplus-types.c
(compile_cplus_instance::enter_scope): Don't use new_scope after
std::move.
This patch fixes two violations of the ARI (use of ATTRIBUTE_UNUSED and
"%ll").
gdb/ChangeLog
* compile/compile-cplus-types.c (compile_cplus_debug_output_1): Use
pulongest instead of "%lld".
* compile/compile-cplus-symbols.c (gcc_cplus_convert_symbol): Remove
ATTRIBUTE_UNUSED.
I see these errors when building with clang:

~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~
Fix the first one by using host_address_to_string.
Fix the second one by comparing to 0 instead. I think the current
comparison simply uses the wrong enum type. Comparing to 0 seems like
the right thing to do, because we want to check whether any flags are
specified.
gdb/ChangeLog:
* compile/compile-cplus-types.c
(compile_cplus_instance::leave_scope): Take the address of scope
object.
(compile_cplus_instance::convert_qualified_base): Compare quals
to 0.
This patch fixes a problem being reported by the buildbot with an
invalid argument to a "%p" printf format. Instead of "%p", the
debug output is changed to use "%s" and host_address_to_string.
gdb/ChangeLog
* compile/compile-cplus-types.c (compile_cplus_instance::enter_scope):
Use "%s" and host_address_to_string instead of "%p" in printf.
This patch adds *basic* support for C++ to the compile feature. It does
most simple type conversions, including everything that C compile does and
your basic "with-classes" type of C++.
I've written a new compile-support.exp support file which adds a new test
facility for automating and simplifying "compile print" vs "compile code"
testing. See testsuite/lib/compile-support.exp and CompileExpression
for more on that. The tests use this facility extensively.
This initial support has several glaring omissions:
- No template support at all
I have follow-on patches for this, but they add much complexity
to this "basic" support. Consequently, they will be submitted separately.
- Cannot print functions
The code template needs tweaking, and I simply haven't gotten to it yet.
- So-called "special function" support is not included
Using constructors, destructors, operators, etc will not work. I have
follow-on patches for that, but they require some work because of the
recent churn in symbol searching.
- There are several test suite references to "compile/1234" bugs.
I will file bugs and update the test suite's bug references before pushing
these patches.
The test suite started as a copy of the original C-language support, but
I have written tests to exercise the basic functionality of the plug-in.
I've added a new option for outputting debug messages for C++ type-conversion
("debug compile-cplus-types").
