Dmitry Vyukov 7d3d94454c tsan: improve memory allocator a bit 
llvm-svn: 162561
 2012-08-24 15:53:14 +00:00
Alexander Potapenko 00492cab3e Revert the erroneous changes made to Makefile.old in r162547 
Remove a spare newline from asan_rtl.cc

llvm-svn: 162548
 2012-08-24 09:31:53 +00:00
Alexander Potapenko fefc1e989c If the program is linked to a dynamic ASan runtime which is not present in DYLD_INSERT_LIBRARIES 
(which, in turn, is required for our interceptors to take effect), re-exec the program with
DYLD_INSERT_LIBRARIES set.

llvm-svn: 162547
 2012-08-24 09:22:05 +00:00
Alexander Potapenko d79d80b4a0 Add add_clang_runtime_shared_library() CMake function and use it to put the shared ASan runtime in the appropriate place. 
llvm-svn: 162546

Dmitry Vyukov 0481ae4722 tsan: allow to override per-thread event trace size 
useful if you don't see the second stack trace

Dmitry Vyukov 7e6347402d tsan: fix new memory allocator 
Deallocate: drain blocks to central cache if cached too much (instead of never drain).
Allocate: batch allocate fixed amount of blocks (instead of all blocks).
This significantly reduces memory consumption of large heavy-multithreaded programs.

Alexey Samsonov 563fb4113c [Sanitizer] Add external symbolizer binary. Next steps - include it in CMake build (produce 32-bit and 64-bit version of it, make sure we can compile LLVM sources with our own flags) and add tests for it. 
llvm-svn: 162442
 2012-08-23 12:39:35 +00:00
Alexander Potapenko 2ebe619340 Re-implement the wrappers for libdispatch functions using blocks where appropriate 
(kudos to Anna Zaks for a good example).
This simplifies the code much and lets us not implement internal parts of libdispatch.

All ASan tests from t32 and t64 should pass with the dylib runtime now.

llvm-svn: 162439
 2012-08-23 09:34:40 +00:00
Alexey Samsonov 419f610a74 [Sanitizer] Switch the symbolization strategy that would be used by sanitizer tools family: as compiling in-process symbolizer into runtime involves certain difficulties, we may instead launch an external symbolizer program (fork + execl) in a subprocess and communicate with it via pipe. 
llvm-svn: 162437
 2012-08-23 07:32:06 +00:00
Alexey Samsonov 4d520640ba [ASan] use write instead of puts in malloc hooks test for ASan, as puts calls malloc on Mac

 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 
llvm-svn: 162355

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.

llvm-svn: 162269
 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.
