Alexey Samsonov d52b9ba38d [FreeBSD] Enable procmaps on FreeBSD. 
This is not the final patch for procmaps, but it's enough for building
sanitizers and tests on FreeBSD.

Patch by Viktor Kutuzov!

Alexey Samsonov 64ffa598ce [Sanitizer] Teach MemoryMappingLayout to dump all loaded modules. 
Use this to implement GetListOfModules() on Mac and on Android
(on Linux we use dl_iterate_phdr).

Alexander Potapenko f8109dd0f8 [libsanitizer] Unmapping the old cache partially invalidates the memory layout, so add 
a flag to skip cache update for cases when that's unacceptable (e.g. lsan).

Alexander Potapenko e2b6d08459 Use a struct to hold the /proc/self/maps buffer on Linux.

 2012-12-03 21:21:22 +00:00
Alexander Potapenko 7811425843 Add caching to the MemoryMappingLayout class on Linux. This is necessary for the cases when a sandbox prevents ASan from reading the mappings 
from /proc/self/maps.
The mappings are currently being cached on each access to /proc/self/maps. In the future we'll need to add an API that allows the client to notify ASan about the sandbox.

Alexey Samsonov 961276af26 [Sanitizer] Extend a symbolizer code. Implemented for Linux only. Use dl_iterate_phdr to get virtual addresses of mapped module sections. To symbolize an address from a module, map this module to memory and obtain pointers to debug info sections. Later these pointers can be passed to constructor of DWARF context-in-memory from LLVM DebugInfo lib.
