Bug ID: 27715
Summary: Don't build tsan for OSX 10.7 and earlier
Product: compiler-rt
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: compiler-rt
Assignee: unassignedb...@nondot.org
Reporter: jerem...@apple.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
The build system attempts to build tsan on older versions of OSX, but this of
course fails. We should automatically detect that tsan should not be built
based on the deployment target.
