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.

Alexander Potapenko 7f3e84c9fd For wild addresses in the shadow or shadow gap areas print an error message instead of crashing on a check. 
Add AddressSanitizer.MemsetWildAddressTest that makes sure a proper error message is printed.

Alexander Potapenko 1bde28b464 Factor the common code out of cf_free and mz_free. 
Introduce the mac_ignore_invalid_free flag (0 by default) which makes both cf_free and mz_free ignore invalid free invocations and leak memory.

Alexey Samsonov 51ae983718 [Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).

Alexander Potapenko 6e216bea86 Fix a bug in parsing boolean flags: we used to take the first char of the key=value string 
instead of the first character of the value.

Alexander Potapenko 442002568c Introduce the check_malloc_usable_size flag (on by default).
