Kostya Serebryany d9a451ab0d [sanitizer] Move termination functions in their own file
Summary:
As suggested by kcc@ in http://reviews.llvm.org/D20084#441418, move the CheckFailed and Die functions, and their associated callback functionalities in their own separate file.
I expended the build rules to include a new rule that would not include those termination functions, so that another project can define their own.
The tests check-{a,t,m,ub,l,e,df}san are all passing.

Kostya Serebryany 54b7162692 [sanitizers] trying to fix Windows build
llvm-svn: 271050
2016-05-27 21:35:58 +00:00
Etienne Bergeron 00f3f6e296 This patch is activating the build of Asan on Windows 64-bits.
It's fixing compilation errors. The runtime is not yet working.

Missing features:

OverrideFunction for x64
an equiv function for inline asm (atomic_compare_exchange_strong)
shadow memory offset needs to be adjusted
RoundUpToInstrBoundary for x64
They will be implemented by subsequent patches.

Patch by Wei Wang.

In one of the already existing apps that I'm testing TSan on, I really see a mutex path that is longer than 10 (but not by much, something like 11-13 actually). Let's raise this to 20 and weaken the assertion so we don't crash.
