2020-09-16libbacktrace, Mach-O : Support PowerPC archs.Iain Sandoe1-0/+6
This adds the PPC architecture variants for Mach-O libbacktrace. With this (as for X86 and Arm) when dsymutil is run on the binary we get a basic usable backtrace. Testsuite results on powerpc-apple-darwin9 are the same as for X86: * btest fails (TBC why) * dwarf5 tests fail because dsymutil does not handle that so far. libbacktrace/ChangeLog: * macho.c (MACH_O_CPU_TYPE_PPC): New. (MACH_O_CPU_TYPE_PPC64): New. Add compile-tests for powerpc to the Mach-O variants.

2020-09-08libbacktrace: avoid ambiguous binary searchIan Lance Taylor1-45/+135
Searching for a range match can cause the search order to not match the sort order, which can cause libbacktrace to miss matching entries.

2019-02-26[libbacktrace] Fix btest-lto for older gccTom de Vries2-1/+6
With gcc 4.8.5, btest_lto ends up with a privatized name for the variable with name 'global': ... $ nm btest_lto | grep ' d ' | grep global 0000000000617150 d global.2530 ... which makes test5 fail: ... test5: unexpected syminfo name got global.2530 expected global ... Fix this failure by accepting this type of name as a valid name in btest_lto. 2019-02-26 Tom de Vries <tdevries@suse.de> * btest.c (test5): Allow global.* as minimal symbol name for global.

2019-02-26[libbacktrace] Require dwz for b3test_dwz_buildidTom de Vries3-35/+46
If dwz is not available, then the libbacktrace test b3test_dwz_buildid fails like this: ... gmake[4]: *** No rule to make target 'b3test_dwz_buildid' ... Fix this by guarding the test with HAVE_DWZ. Tested on x86_64 with and without dwz installed. 2019-02-26 Tom de Vries <tdevries@suse.de> * Makefile.am (TESTS): Only add b3test_dwz_buildid if HAVE_DWZ. * Makefile.in: Regenerate.

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
