[LLVMdev] Make PPC JIT support inline assembly?

[陳韋任]

Hi, all

  It seems PPC JIT does not recognize inline assembly.
For example, when I give LLVM IR belows to PPC JIT,

%0 = tail call i32* asm "", "={r10}"() nounwind ; <i32*> [#uses=1]  

  it complaints that inline assembly is not a supported
instruction. x86 JIT works fine, however.

  Is there a reason that makes PPC JIT not support inline
assembly?

  Currently, we modify PPCGenCodeEmitter.inc, then rebuild
LLVM to let ppc recognize inline assembly (see attachment).
Is there a better way to make PPC JIT support inline assembly?

  Any suggestion appreciated.

Regards,
chenwj
