2019-02-12[libbacktrace] Handle bsearch with NULL base in dwarf_lookup_pcTom de Vries2-2/+9
The call to bsearch in dwarf_lookup_pc can have NULL as base argument when the nmemb argument is 0. The base argument is required to be pointing to the initial member of an array of nmemb objects. It is not specified what constitutes a valid pointer to an array of 0 objects, but glibc declares base with attribute non-null, so the NULL will trigger a sanitizer runtime error. Fix this by only calling bsearch if nmemb != 0. 2019-02-12 Tom de Vries <tdevries@suse.de> PR libbacktrace/81983 * dwarf.c (dwarf_lookup_pc): Don't call bsearch if nmemb == 0. From-SVN: r268796

2019-02-08[libbacktrace] Declare external backtrace fns noinlineTom de Vries4-3/+9
The backtrace functions backtrace_full, backtrace_print and backtrace_simple walk the call stack, but make sure to skip the first entry, in order to skip over the functions themselves, and start the backtrace at the caller of the functions. When compiling with -flto, the functions may be inlined, causing them to skip over the caller instead. Fix this by declaring the functions with __attribute__((noinline)). 2019-02-08 Tom de Vries <tdevries@suse.de> * backtrace.c (backtrace_full): Declare with __attribute__((noinline)). * print.c (backtrace_print): Same. * simple.c (backtrace_simple): Same.

2019-01-29[libbacktrace] Don't assign check_PROGRAMS to TESTSTom de Vries3-77/+93
In automake files, the check_PROGRAMS variable lists programs that need to be build for testing, and TESTS lists the programs that need to be run. The libbacktrace/Makefile.am uses a shortcut: ... TESTS = $(check_PROGRAMS) ... to make sure that each program added with: ... check_PROGRAMS += foo ... is both build and run. However, for the allocfail.sh test, we need allocfail to be build and allocfail.sh to be run: ... check_PROGRAMS += allocfail TESTS += allocfail.sh ... but the shortcut causes allocfail also to be run, which is not required. Fix this by removing the short-cut, allowing check_PROGRAMS to retain its original semantics, and introducing a variable BUILDTESTS for programs that need to be both build and run. 2019-01-29 Tom de Vries <tdevries@suse.de> * Makefile.am: Replace check_PROGRAMS with BUILDTESTS, except for allocfail.

2019-01-28[libbacktrace] Fix and simplify xcoff_%.c pattern ruleTom de Vries3-4/+12
When generating xcoff_%.c, the last command is a sed command. In case of a sed failure, this will leave an incomplete file, which will appear as up to date to make, so consequently it will not be regenerated. Fix this by sedding into a temporary file instead. Also, use $< to access the prerequisite xcoff.c, instead of spelling out the file name once more. 2019-01-28 Tom de Vries <tdevries@suse.de> * Makefile.am (xcoff_%.c): Generate sed result into temporary file.

2019-01-25[libbacktrace] Fix strrchr segfaultTom de Vries4-8/+29
Currently, when running a libbacktrace testcase t with .gnu_debuglink to t.debug, and t.debug having a .gnu_debugaltlink to t.alt.debug, a segfault is triggered when calling strrchr with a NULL string from elf_find_debugfile_by_debuglink. The NULL string originates from the elf_add called for the .gnu_debugaltlink, which uses NULL as filename argument. Fix this by using "" as filename argument instead. 2019-01-25 Tom de Vries <tdevries@suse.de> * elf.c (elf_add): When handling .gnu_debugaltlink, call elf_add with filename == "". * Makefile.am (TESTS): Add btest_dwz_gnudebuglink. * Makefile.in: Regenerate.

2018-12-28[libbacktrace] Reduce memory usage in build_address_mapTom de Vries2-0/+18
In build_address_map we allocate a unit, and then look for addresses in the unit, which we store in the addrs vector, with the elements pointing to the unit. However, if we cannot find addresses in the unit, the allocated unit is not used. Fix this by detecting if the allocated unit has been used, and reusing it otherwise. Bootstrapped and reg-tested on x86_64. 2018-12-28 Tom de Vries <tdevries@suse.de> * dwarf.c (build_address_map): Reuse unused units. From-SVN: r267445
2018-12-28[libbacktrace] Simplify memory management in build_address_mapTom de Vries2-12/+13
In the main loop in build_address_map, we first read the abbrevs into a local variable abbrevs, and then allocate the corresponding unit, after which we assign the abbrevs to the unit. This results in dedicated free-upon-failure handling for the variable, and extra code to make sure that free-upon-failure doesn't trigger once the unit has taken ownership of the abbrevs. Simplify this by reversing the order of abbrev reading and unit allocation, and eliminating the abbrevs local variable. Bootstrapped and reg-tested on x86_64. 2018-12-28 Tom de Vries <tdevries@suse.de> * dwarf.c (build_address_map): Simplify by removing local variable abbrevs. From-SVN: r267444
2018-12-28[libbacktrace] Fix memory leak in loop in build_address_mapIan Lance Taylor2-26/+44
When failing in build_address_map, we free the unit that's currently being handled in the loop, but the ones that already have been allocated are leaked. Fix this by keeping track of allocated units in a vector, and releasing them upon failure. Also, now that we have a vector of allocated units, move the freeing upon failure of the abbrevs associated with each unit to build_address_map, and remove the now redundant call to free_unit_addrs_vector.

2018-10-31Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).Joseph Myers7-1080/+2026
This patch updates GCC to use autoconf 2.69 and automake 1.15.1. (That's not the latest automake version, but it's the one used by binutils-gdb, with which consistency is desirable, and in any case seems a useful incremental update that should make a future update to 1.16.1 easier.) The changes are generally similar to the binutils-gdb ones, and are copied from there where shared files and directories are involved (there are some further changes to such shared directories, however, which I'd expect to apply to binutils-gdb once this patch is in GCC). Largely, obsolete AC_PREREQ calls are removed, while many AC_LANG_SOURCE calls are added to avoid warnings from aclocal and autoconf. Multilib support is no longer included in core automake, meaning that multilib.am needs copying from automake's contrib directory into the GCC source tree. Autoconf 2.69 has Go support, so local copies of that support are removed. I hope the D support will soon be submitted to upstream autoconf so the local copy of that can be removed in a future update. Changes to how automake generates runtest calls mean quotes are removed from RUNTEST definitions in five lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm, libphobos, libvtv; some others have RUNTEST definitions without quotes, which are still OK); libgo and libphobos also get -Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST do not generate automake warnings. Note that the regeneration did not include regeneration of fixincludes/config.h.in (attempting such regeneration resulted in all the USED_FOR_TARGET conditionals disappearing; and I don't see anything in the fixincludes/ directory that would result in such conditionals being generated, unlike in the gcc/ directory). Also note that libvtv/testsuite/other-tests/Makefile.in was not regenerated; that directory is not listed as a subdirectory for which Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm not sure how it's meant to be regenerated. While I mostly fixed warnings should running aclocal / automake / autoconf, there were various such warnings from automake in the libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos directories that I did not fix, preferring to leave those to the relevant subsystem maintainers. Specifically, most of those warnings were of the following form (example from libgfortran): Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory, Makefile.am:48: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. I think it's best for the relevant maintainers to add subdir-objects and do any other associated Makefile.am changes needed. In some cases the paths in the warnings involved ../; I don't know if that adds any extra complications to the use of subdir-objects. I've tested this with native, cross and Canadian cross builds. The risk of any OS-specific issues should I hope be rather lower than if a libtool upgrade were included (we *should* do such an upgrade at some point, but it's more complicated - it involves identifying all our local libtool changes to see if any aren't included in the upstream version we update to, and reverting an upstream libtool patch that's inappropriate for use in GCC); I think it would be better to get this update into GCC so that people can test in different configurations and we can fix any issues found, rather than to try to get more and more testing done before it goes in. top level: 2018-10-31 Joseph Myers <joseph@codesourcery.com> PR bootstrap/82856 * multilib.am: New file.
