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.

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.

Test that child threads use the ASan allocator, that allocated memory can be passed to another thread and deallocated on it.
This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=81

 2012-06-06 13:58:39 +00:00
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 442002568c Introduce the check_malloc_usable_size flag (on by default). 
When the flag is set to zero, we do not check for errors in malloc_usable_size.
