Also convert some FALLTHROUGH comments to ATTRIBUTE_FALLTHROUGH.
* internal.h: Use __has_attribute to check for fallthrough
attribute.
* elf.c (elf_zstd_decompress): Use ATTRIBUTE_FALLTHROUGH rather
than a FALLTHROUGH comment.
We could get an infinite recursion in an odd case in which a
.gnu_debugdata section was added to a debug file, and mini_debuginfo
was put into the debug file, and the debug file was put into a
/usr/lib/debug directory to be found by build ID. This combination
doesn't really make sense but we shouldn't get an infinite recursion.
* elf.c (elf_add): Don't use .gnu_debugdata if we are already
reading a debuginfo file.
* Makefile.am (m2test_*): New test targets.
(CHECK_PROGRAMS): Add m2test.
(MAKETESTS): Add m2test_minidebug2.
(%_minidebug2): New pattern.
(CLEANFILES): Remove minidebug2 files.
* Makefile.in: Regenerate.
Patch from Björn Schäpers <bjoern@hazardy.de>.
* configure.ac: Checked for tlhelp32.h
* pecoff.c: Include <tlhelp32.h> if available.
(backtrace_initialize): Use tlhelp32 api for a snapshot to
detect loaded modules.
(coff_add): New argument for the module handle of the file,
to get the base address.
* configure, config.h.in: Regenerate.
This should fix a testsuite problem with Solaris ld that supports zlib
but not zlib-gabi.
* configure.ac: Test --compress-debug-sections=zlib-gnu and
--compress-debug-sections=zlib-gabi separately, setting new
automake conditionals.
* Makefile.am (ctestg, ctestg_alloc): Only build if
HAVE_COMPRESSED_DEBUG_ZLIB_GNU.
(ctesta, ctesta_alloc): Only build if
HAVE_COMPRESSED_DEBUG_ZLIB_GABI.
(ctestzstd_alloc): New test if HAVE_COMPRESSED_DEBUG_ZSTD.
* configure, Makefile.in: Regenerate.
These become another symbol table to search. This is needed if people
use --strip-all rather than --strip-debug when adding a debuglink
section.
Patch is from GitHub user pickard1.
Fixes https://github.com/ianlancetaylor/libbacktrace/issues/113.
* elf.c (elf_add): Add the symbol table from a debuginfo file.
* Makefile.am (MAKETESTS): Add buildidfull and gnudebuglinkfull
variants of buildid and gnudebuglink tests.
(%_gnudebuglinkfull, %_buildidfull): New patterns.
* Makefile.in: Regenerate.
Patch from Björn Schäpers.
* fileline.c: Include <windows.h> if available.
(windows_get_executable_path): New static function.
(fileline_initialize): Call windows_get_executable_path.
* configure.ac: Checked for windows.h
* configure: Regenerate.
* config.h.in: Regenerate.
Recent Darwin versions place contraints on the use of run paths
specified in environment variables. This breaks some assumptions
in the GCC build.
This change allows the user to configure a Darwin build to use
'@rpath/libraryname.dylib' in library names and then to add an
embedded runpath to executables (and libraries with dependents).
The embedded runpath is added by default unless the user adds
'-nodefaultrpaths' to the link line.
For an installed compiler, it means that any executable built with
that compiler will reference the runtimes installed with the
compiler (equivalent to hard-coding the library path into the name
of the library).
During build-time configurations any "-B" entries will be added to
the runpath thus the newly-built libraries will be found by exes.
Since the install name is set in libtool, that decision needs to be
available here (but might also cause dependent ones in Makefiles,
so we need to export a conditional).
This facility is not available for Darwin 8 or earlier, however the
existing environment variable runpath does work there.
We default this on for systems where the external DYLD_LIBRARY_PATH
does not work and off for Darwin 8 or earlier. For systems that can
use either method, if the value is unset, we use the default (which
is currently DYLD_LIBRARY_PATH).
ChangeLog:
* configure: Regenerate.
* configure.ac: Do not add default runpaths to GCC exes
when we are building -static-libstdc++/-static-libgcc (the
default).
* libtool.m4: Add 'enable-darwin-at-runpath'. Act on the
enable flag to alter Darwin libraries to use @rpath names.
