New Revision: 162809
URL: http://llvm.org/viewvc/llvm-project?rev=162809&view=rev
Log:
Some flag cleanup for the sanitizer runtimes.
This hoists most of the CFLAGS into a common variable. It also adds
detection for -Wno-c99-extensions and uses it to silence a pile of
warnings.
Finally, it switches to the proper flag -rdynamic.
With this, the cmake build is warning free on my bootstrap Linux build.

# Because compiler-rt spends a lot of time setting up custom compile flags,
# define a handy helper function for it. The compile flags setting in CMake
# has serious issues that make its syntax challenging at best.
