Hi,
The current libsanitizer changes to the trunk breaks nightly PowerPC builds (ppc64 & e600).
Is it a known issue? Should I open a bug for this?

Function: void GetPcSpBp(void *context, uptr *pc, uptr *sp, uptr *bp) {
It seems the check for PowerPC target macro has been removed in the above mentioned function.
