* tsan: ignore interceptors coming from specified librariesDmitry Vyukov2013-10-0320-58/+247
| | | | | | | | | | | | | | | LibIgnore allows to ignore all interceptors called from a particular set of dynamic libraries. LibIgnore remembers all "called_from_lib" suppressions from the provided SuppressionContext; finds code ranges for the libraries; and checks whether the provided PC value belongs to the code ranges. Also make malloc and friends interceptors use SCOPED_INTERCEPTOR_RAW instead of SCOPED_TSAN_INTERCEPTOR, because if they are called from an ignored lib, then must call our internal allocator instead of libc malloc. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@191897 91177308-0d34-0410-b5e6-96231b3b80d8
