I have a question about inserting instructions into the LLVM IR. I can insert instructions, but my operands do not have the right type, so it fails an assertion at runtime. I am trying to insert an immediate load instructions, as a means of claiming a new register. Here is what I do: Builder.SetInsertPoint(LLVMBB, I); // The following line looks to me like it would have a chance of loading

commend "llvm-dis" can print out the LLVM IR but is there any way to printout the SelectionDAG? like: add (x , add (y,z)) Thank you for your assistance, Kao Chang _________________________________________________________________ 用部落格分享照片、影音、趣味小工具和最愛清單，盡情秀出你自己 — Windows Live Spaces http://home.spaces.live.com/?showUnauth=1&lc=1028 -------------- next part -------------- An HTML

I have been doing some playing with the patterns that define complex instructions, and I saw a behavior that doesn't look right. I think its a bug in the PPC backend. The 32-bit PPC .td file defines a pattern for the fnmsubs instruction like this: def : Pat<(fsub F4RC:$B, (fmul F4RC:$A, F4RC:$C)), (FNMSUBS F4RC:$A, F4RC:$C, F4RC:$B)>,
