similar to: [LLVMdev] Help with PPC64 JIT

Hi Adhemerval Zanella, the old JIT infrastructure is going away, to be replaced by "MC-JIT" (try passing -use-mcjit to lli). It sounds like you are working on the old JIT, so I suggest you work instead on getting MC-JIT working on powerpc. Ciao, Duncan. > I am currently working with PPC64 JIT support for LLVM.

Hi all, When you genetate code on PowerPC you need to explicitly invalidate the instruction cache to force the processor to reread it. In LLVM there is code to do this for function stubs on Macintosh, but not for other platforms and not for JITted code generally. The attached patch adds support for GNU platforms, but I can't figure out a nice way to call it for all generated code. Can

Meaning one LLVM compiler cannot generate both

Marcus Meissner did the ppc64 port, I did the update for crt0.S.
