Iain Sandoe	753968c2e8	libbacktrace, Mach-O : Support PowerPC archs. 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. Close #55	3 years ago

Ian Lance Taylor	430dc8b6fe	libbacktrace: avoid ambiguous binary search Searching for a range match can cause the search order to not match the sort order, which can cause libbacktrace to miss matching entries.
