[LLVMdev] Selfhost LLVM and Clang on ARM

[陳韋任]

Hi, all

  I am trying to selfhost LLVM and Clanf on ARM. Hopefully
doing this can reveal what version of GCC is broken. But I
have a concern about the following message while building
LLVM and Clang by using clang (selfhost build).

---
llvm[1]: Compiling DeltaAlgorithm.cpp for Debug build
/tmp/cc-DqWGS1.s: Assembler messages:
/tmp/cc-DqWGS1.s:8963: Rd and Rm should be different in mul
llvm[1]: Compiling PluginLoader.cpp for Debug build
/tmp/cc-wpJpuX.s: Assembler messages:
/tmp/cc-wpJpuX.s:724: rdhi, rdlo and rm must all be different
/tmp/cc-wpJpuX.s:728: Rd and Rm should be different in mla
---

  What does those message mean? Thanks!

Regards,
chenwj
