Alexey Samsonov 4d520640ba [ASan] use write instead of puts in malloc hooks test for ASan, as puts calls malloc on Mac 
llvm-svn: 162359
 2012-08-22 13:32:37 +00:00
Alexey Samsonov a85b6b8154 [ASan] get rid of ASAN_USE_EXTERNAL_SYMBOLIZER compiler def in favor of __asan_set_symbolize_callback interface function. Now the user doesn't have to recompile ASan runtime to provide its own symbolizer 
llvm-svn: 162358
 2012-08-22 13:31:37 +00:00
Alexey Samsonov de17f86655 [ASan] make ASan malloc/free hooks weak interface functions, overridable by user. Now the user can control malloc/free hooks without recompiling ASan runtime

 2012-08-21 14:43:36 +00:00
Kostya Serebryany 676bcdb838 [asan] run-time part of the initialization order checker. Patch by Reid Watson with some bits from kcc. The sub-pass is off by default for now. On simple tests it works fine.

 2012-08-21 08:24:35 +00:00
Alexey Samsonov e6704ee109 [Sanitizer] define InternalScopedBuffer to replace large arrays on stack. It is defined analogous to similar class in tsan and should replace it.
