On powerpc64 I hit
/home/polacek/gcc/libsanitizer/asan/asan_linux.cc:209:3: error: #error
"Unsupported arch"
# error "Unsupported arch"
because the merge (aka clang's r196802) removed ppc64 hunk of code:
-# elif defined(__powerpc__) || defined(__powerpc64__)
- ucontext_t *ucontext = (ucontext_t*)context;
- *pc = ucontext->uc_mcontext.regs->nip;
- *sp = ucontext->uc_mcontext.regs->gpr[PT_R1];
- // The powerpc{,64}-linux ABIs do not specify r31 as the frame
- // pointer, but GCC always uses r31 when we need a frame pointer.
- *bp = ucontext->uc_mcontext.regs->gpr[PT_R31];
-# elif defined(__sparc__)
