Sergey Matveev 9be70fbda9 [sanitizer] Introduce VReport and VPrintf macros and use them in sanitizer code. 
Instead of "if (common_flags()->verbosity) Report(...)" we now have macros.

Alexey Samsonov 4d369187ec [Sanitizer] Print symbolized stack frame using a single Printf() call. 
This reduces the number of "write" syscalls performed to print a single
stack frame description, and makes sanitizer output less intermixed with
program output. Also, add a number of unit tests.

Peter Collingbourne ffaf2eac4d [nolibc] Move all platforms to internal_getpid. 
Before, we had an unused internal_getpid function for Linux, and a
platform-independent GetPid function.  To make the naming conventions
consistent for syscall-like functions, the GetPid syscall wrapper
in sanitizer_posix.cc is moved to sanitizer_mac.cc, and GetPid is
renamed to internal_getpid, bringing the Linux variant into use.

Alexander Potapenko 1f78ad5da4 [ASan] Reduce the local buffer size in Report() not to fail the check enforced when building TSan runtime. 
llvm-svn: 176804
 2013-03-11 13:36:39 +00:00
Alexander Potapenko 18c916c6c5 [ASan] Try to use a small (512 bytes) stack-local buffer in Report() for short messages, fall back to MmapOrDie() in the case of a failure. 
This shall eliminate most of the cryptic "ERROR: failed to mmap" messages caused by recursively calling MmapOrDie() from MmapOrDie().

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).
