* tsan: fix Go ppc64le buildDmitry Vyukov2019-10-151-0/+2
| | | | | | | | | | | This #define is in the non-Go ppc64le build but not in the Go build. Reviewed-in: https://reviews.llvm.org/D68046 Author: randall77 (Keith Randall) git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@374868 91177308-0d34-0410-b5e6-96231b3b80d8
* [tsan, go] fix Go windows buildVitaly Buka2019-10-071-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: Don't use weak exports when building tsan into a shared library for Go. gcc can't handle the pragmas used to make the weak references. Include files that have been added since the last update to build.bat. (We should really find a better way to list all the files needed.) Add windows version defines (WINVER and _WIN32_WINNT) to get AcquireSRWLockExclusive and ReleaseSRWLockExclusive defined. Define GetProcessMemoryInfo to use the kernel32 version. This is kind of a hack, the windows header files should do this translation for us. I think we're not in the right family partition (we're using Desktop, but that translation only happens for App and System partitions???), but hacking the family partition seems equally gross and I have no idea what the consequences of that might be.
