Ken Thomases d5739561d8 dbghelp: Provide a default value for DYLD_FALLBACK_LIBRARY_PATH, which is closer to how dyld behaves. 2015-09-18 14:59:01 +02:00
Ken Thomases 8d6b349409 dbghelp: Fix a comment to reflect what the code's actually doing. 2015-09-18 14:58:58 +02:00
Ken Thomases f458cd844a dbghelp: On Mac, get the wineloader path from the target or our own process before resorting to guessing.
This makes backtraces more reliably complete when WINELOADER isn't set
and the loader isn't in a typical location.

Ken Thomases 49f0bf6f0b dbghelp: Ignore Mach-O segments other than __TEXT for images in dyld's shared cache.
Images in the shared cache have their segments mapped non-contiguously.  We
don't know how to find where the non-__TEXT segments actually are.  Also, the
code assumes that the image is mapped contiguously in various places.  So, we
just ignore those segments.

Treating the non-contiguous segments as though they were contiguous caused
their apparent memory ranges to overlap, leading to addresses being attributed
to the wrong module, let alone symbol.

Ken Thomases be68890cac dbghelp: Fix a copy-paste error in comparing Mach-O segment names. 2015-08-04 12:21:58 +02:00
Ken Thomases 5c39776327 dbghelp: Add support for loading an external DWARF debug info file associated with a Mach-O module.
Such external debug info files are created by the dsymutil command.  Usually, it
creates a <name>.dSYM bundle directory but it can also produce a <name>.dwarf
flat file.  The code will find and use either.  It first checks if such a bundle
or file is adjacent to the module binary.  If it's not, it uses Spotlight to
search for a .dSYM bundle based on the binary's UUID, which is what gdb and lldb
do, too.  That way, it can find it anywhere on the system.

Ken Thomases 70565f1b8b dbghelp: Don't parse the DWARF info from Mach-O files if we were requested to only provide public symbols.
This now works more like how the ELF and PE support works.

Ken Thomases 3a9698f4af dbghelp: Parse the DWARF information in Mach-O modules.
At this point, this is just the .eh_frame information used for walking the stack.

Ken Thomases 0bfa11455c dbghelp: Implement the image_private.h functions for Mach-O modules. 2015-06-25 14:29:38 +09:00
Ken Thomases 729b53fb9e dbghelp: For Mach-O, keep the module file mapped for as long as the module is tracked. 2015-06-25 14:02:17 +09:00
Ken Thomases e15e9331cb dbghelp: Move the macho_file_map structure into image_file_map. 2015-06-25 14:02:12 +09:00
Ken Thomases dcbec3bf6a dbghelp: Use existing IMAGE_NO_MAP constant instead of redundant MACHO_NO_MAP. 2015-06-25 14:02:00 +09:00
Ken Thomases 41d741761f dbghelp: Remove the unused arch_size field of struct macho_file_map.
It was set, but never read.

Ken Thomases 4923f9afd5 dbghelp: Enable enumerating and loading 64-bit Mach-O modules. 2015-06-25 14:01:49 +09:00
Ken Thomases 378d557d77 dbghelp: Fix a leak of the Mach-O module structure by adding a module_remove callback. 2015-06-25 14:01:32 +09:00
Ken Thomases 8430ebc6b5 dbghelp: Eliminate an unnecessary parameter from macho_load_debug_info().
From outside of macho_module.c, it's only called with NULL.  When it's
called with a non-NULL parameter, it's just a thin wrapper around
macho_load_debug_info_from_map(), so the code can just call that
directly.

Charles Davis b3232e7c9d dbghelp: Support 64-bit dyld_all_image_infos structures, too. 2015-02-06 22:35:23 +09:00
Ken Thomases 5acf1510fb dbghelp: Ignore the __PAGEZERO segment.
It made it seem as though the wineloader always started at address 0.
Issue identified by Jacek Caban.

Ken Thomases 6903238948 dbghelp: Don't check version of Mach-O dyld_all_image_infos structure.
The structure has changed repeatedly, but always in a backward compatible way.
The version check was only hampering us.
