Make sure to use DAG.getTargetNode() with custom opcodes. "target" nodes are encoded with an implicit delta added to their enum value. -Chris -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org...

Hi! I noticed in the LegalizeDAG.cpp (SelectionDAGLegalize::LegalizeOp): case ISD::INIT_TRAMPOLINE: case ISD::FRAMEADDR: case ISD::RETURNADDR: // These operations lie about being legal: when they claim to be legal, // they should actually be custom-lowered. Action = TLI.getOperationAction(Node->getOpcode(), Node->getValueType(0)); if (Action == TargetLowering::Legal) Action = TargetLowe...

Hi, I'm gettign an assertion fail/crash in X86FrameLowering::GetFrameIndexReference when compiling the following bitcode: https://gist.github.com/carlokok/868cddebeb9acc8ccbac6253de0480b0 I tried removing the llvm.frameaddres calls but that's not it, where can I start looking for what my mistake here is? Code seems to verify just fine. ; #0 0x00e1afe8 llvm::X86FrameLowering::getFrameIndexReference(class llvm::MachineFunction const &,int,unsigned int &)const c:\p\llvm\llvm\lib\target\x86\x86frameloweri...

There are LLVM 2.9 RC1 pre-release tarballs source available. You can find them here: http://llvm.org/pre-releases/2.9/ Please download them, build them, and compile things to your heart's content. And most importantly file a bunch of bug reports. :-) Share and enjoy! -bw
