Alexey Samsonov cea6239219 [ASan] Due to data races, ASan malloc stats are inaccurate, which may cause certain ASan interface functions returning negative values (casted to unsigned). Return a reasonable value if such a case is detected.

asan_malloc_mac.cc [Sanitizer] Remove unneeded returns after UNIMPLEMENTED macro 2012-10-09 08:51:08 +00:00
asan_malloc_win.cc [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. 2012-09-24 11:43:40 +00:00
asan_mapping.h A few tweaks for building ASanRT against Android NDK. 2012-08-27 11:15:55 +00:00

asan_report.cc [asan] change the asan output slightly to avoid user confusion: a) add ':' after 'AddressSanitizer' and b) changed 'crashed' to 'SEGV' 2012-10-15 13:04:58 +00:00
asan_report.h [ASan] Add print_full_thread_history runtime option (on by default) that prints all full thread creation paths for threads involved in ASan error report 2012-09-05 07:37:15 +00:00
asan_rtl.cc [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) 2012-10-02 14:06:39 +00:00
asan_stack.cc [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. 2012-10-02 12:11:17 +00:00
asan_stack.h [asan] actually move StackTrace to sanitizer_common 2012-08-28 14:11:57 +00:00

asan_thread_registry.cc [ASan] Due to data races, ASan malloc stats are inaccurate, which may cause certain ASan interface functions returning negative values (casted to unsigned). Return a reasonable value if such a case is detected. 2012-10-24 09:19:11 +00:00
asan_thread_registry.h Give more accurate malloc statistics to malloc_zone_statistics(). 2012-09-12 15:29:50 +00:00

AddressSanitizer RT
================================
This directory contains sources of the AddressSanitizer (asan) run-time library.
We are in the process of integrating AddressSanitizer with LLVM, stay tuned.

Directory structre:
README.txt       : This file.
Makefile.mk      : File for make-based build.
CMakeLists.txt   : File for cmake-based build.
asan_*.{cc,h}    : Sources of the asan run-time lirbary.
scripts/*        : Helper scripts.
tests/*          : ASan unit tests.
lit_tests/*      : ASan output tests.

Also ASan runtime needs the following libraries:
lib/interception/      : Machinery used to intercept function calls.
lib/sanitizer_common/  : Code shared between ASan and TSan.

Currently ASan runtime can be built by both make and cmake build systems.
(see compiler-rt/make and files Makefile.mk for make-based build and
files CMakeLists.txt for cmake-based build).

ASan unit and output tests work only with cmake. You may run this
command from the root of your cmake build tree:

make check-asan
