Vedant Kumar 10c3102071 [ubsan] Diagnose invalid uses of builtins (clang) ... On some targets, passing zero to the clz() or ctz() builtins has undefined behavior. I ran into this issue while debugging UB in __hash_table from libcxx: the bug I was seeing manifested itself differently under -O0 vs -Os, due to a UB call to clz() (see: libcxx/r304617). This patch introduces a check which can detect UB calls to builtins. llvm.org/PR26979 Differential Revision: https://reviews.llvm.org/D34590 llvm-svn: 309459		2017-07-29 00:19:51 +00:00
