[llvm-commits] Please review: adding Function attribute "ThreadSafety"

[Kostya Serebryany]

Hello,

I would like to add one more function attribute: "ThreadSafety".
Functions with this attribute will be instrumented by run-time
thread-safety analysis tools (e.g. with ThreadSanitizer).
This is similar to "AddressSafety" attribute used by AddressSanitizer (and
SAFECode?).

Clang already has the attribute
"__attribute__((no_thread_safety_analysis))" which is used to disable
static thread-safety analysis.
http://clang.llvm.org/docs/LanguageExtensions.html#threadsafety
In a separate change we will teach clang to unset ThreadSafety
when no_thread_safety_analysis is present.
(exactly as we do for no_address_safety_analysis and AddressSafety)

Please review.

Thanks,

--kcc
