Alexander Potapenko d2f6b97417 Avoid calling __asan_init from memcpy(), memmove(), memset() during libSystem initialization. 
Fixes http://code.google.com/p/address-sanitizer/issues/detail?id=117.

Alexander Potapenko 77c0ac2336 Do not patch the instruction address when symbolizing the reports. 
Instead, print the correct address at runtime.

Alexey Samsonov 78c340d205 [ASan] Change __asan_set_on_error_callback to weak overridable __asan_on_error, so that ASan would call the latter even if it finds the error early (i.e. during module initialization) 
llvm-svn: 165008

llvm-svn: 165003
 2012-10-02 12:35:42 +00:00
Alexey Samsonov e29c6731aa [Sanitizer/ASan] Simplify the code that prints and symbolizes stack traces. Fall back to module+offset if user-provided symbolizer failed. Use weak function __asan_symbolize instead of __asan_set_symbolize_callback in ASan interface, so that we're able to symbolize reports for errors that happen before the main() is called, for example, during module initialization.

Evgeniy Stepanov cb9cf0f907 Add a missing const qualifier.

 2012-09-27 13:21:08 +00:00
Evgeniy Stepanov f7f616ba66 Quick fix data/bss detection in TSan. 
The old way breaks when a module's bss is adjacent to the [heap] vm area.
Both ways are not very reliable, though.

Alexey Samsonov a555b3faf4 [ASan] Apply some ASan-relevant pieces of patch by Ruben Van Boxem. In the same time, remove ASan from CMake build on Windows after conversation with Timur. We don't want to support building ASan on Windows until it is in a working state.

Alexey Samsonov 341e5bcb45 [TSan] port all output tests to lit and move them to lit_tests directory. This makes 'make check-tsan' command test both unit and output TSan tests. Old custom makefiles for running TSan tests are still functional as well.
