Alexey Samsonov 5062359502 cmake for compiler-rt: add a function to set output dirs for compiler runtimes equal to directory used by Clang driver. Use it for ASan runtime. Also, make sure that ASan unit tests depend on the ASan runtime.

Alexey Samsonov c145b02607 [ASan] fixup for r160712: provide a default definition for weak __asan_default_options() 
llvm-svn: 160718
 2012-07-25 10:40:57 +00:00
Alexander Potapenko 9bac1cedbc Make __asan_default_options a weak function that returns a const char*. 
Users may define it to override the default ASan options.
This function has to be marked with __attribute__((no_address_safety_analysis)), because it is called before ASan is fully initialized.

Add an output test checking the __asan_default_options functionality.

Alexey Samsonov 96b9393f2d [ASan] Support for cmake build of ASan unittests in 32-bit LLVM build. Currently, to run ASan unit tests both for 32- and 64 bits one has to maintain two distinct LLVM builds. In a bright future, we'd like to use a single build for this
