Alexey Samsonov 1cb684381a [Sanitizer] Add generic ThreadRegistry class for sanitizer runtimes. This class holds basic thread bookkeeping logic and allows specific sanitizer runtimes to create thread contexts and mark threads as created/running/joined etc. The class is based on the way we currently store thread contexts in TSan.

Kostya Serebryany 67b1478914 [asan] use 4Tb of address space for the asan allocator instead of 1Tb. This increases the memory available for a single size class from 16Gb to 64Gb. The total VM footprint becomes 20Tb

Kostya Serebryany 138b155042 [sanitizer] use fewer size classes in the allocator to reduce the memory footprint. There is no all-size-fits-all constant here, but this change is positive or neutral on several large apps I've tested

Reid Kleckner c9d382b5a4 [msan] intercept dlopen and clear shadow for it
Summary:
The loader does not call mmap() through the PLT because it has to
bootstrap the process before libc is present.  Hooking dlopen() isn't
enough either because the loader runs module initializers before
returning, and they could run arbitrary msan instrumented code.

If msandr is present, then we can intercept the mmaps from dlopen at the
syscall layer and clear the shadow there.  If msandr is missing, we
clear the shadow after dlopen() and hope any initializers are trivial.

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().

Nick Lewycky 593eeb000a Don't emit the extra checksum into the .gcda file if the user hasn't asked for
it. Fortunately, versions of gcov that predate the extra checksum also ignore 
any extra data, so this isn't a problem. This matches the API change made in
r176745.
