Simon Wallis c6b11bb4ce Clang crash targeting ARM or Thumb when assembling a prel31 relocation variant ... Summary: In the assembler or inline assembler, attempting to use an invalid fixup type gives a crash with a segmentation fault. __attribute__((naked)) void foo(void) { __asm__("mov r9, :lower16:bar(prel31)"); } This should give a proper error message when building for ARM or Thumb. This brings it in line with AARCH64. This fixes all 8 instances of llvm_unreachable("Unsupported Modifier"); in ARM/MCTargetDesc/ARMELFObjectWriter.cpp. A test is provided for each instance.
