Hi Gary, You have to write custom encoding logic in C++ for this. This should go in PPCCodeEmitter::emitBasicBlock. I admit this isn't very elegant. A better solution would be to fix the lowering to produce two instructions instead of this pseudo instruction. -Chris

Hi all, I'm trying to figure out how to add the instructions required for llvm.atomic.cmp.swap.i32 on PowerPC. I figured out LWARX (patch attached) but the other two (CMP_UNRESw and STWCX) require multiple instructions: let Defs = [CR0] in { def STWCX : Pseudo<(outs), (ins GPRC:$rS, memrr:$dst, i32imm:$label), "stwcx. $rS, $dst\n\tbne-

I'd be interested to hear how that's being done - if Brian would reply to the list about it, I'd appreciate it. -mike On Aug 19, 2004, at 3:39 PM, Vikram S.

Is it possible to get llvm to generate native machine code without using gcc and friends ? Do I use lli ? I'd like to directly create executable code that i can stick in memory somewhere and jump into (call). (I'm looking to use llvm in a BSD licensed project). Simon. -- Simon Burton, B.Sc.

Qiuyu, The dynamic optimization project (an internal research project in our group) uses some way to map LLVM basic blocks to native code addresses. If this is what you want, perhaps you can ask Brian Gaeke (gaeke at uiuc.edu) to give you some information about how that is done. --Vikram http://www.cs.uiuc.edu/~vadve http://llvm.cs.uiuc.edu/ On Aug 19, 2004, at 5:11 PM, Misha Brukman
