...bb1 ] br label %return This compiles correctly when I use the X86 or PPC backend, but results in the following error with Alpha backend: LLVM ERROR: Cannot select: 0x95a0490: i64 = BlockAddress<@main, %bb1> [ID=3] I also found the following line commented out in the file lib/Target/Alpha/AlphaISelLowering.cpp: // setOperationAction(ISD::BRIND, MVT::Other, Expand); My guess is that indirectbr is not implemented for Alpha. If that's the case, where do I need to make changes to implement this instruction? Thank you, Giang -------------- next part -------------- An HTML attachmen...

The Alpha backend does this for division and remainder of integers. See AlphaISelLowering.cpp:501 for the lowering to a custom call node, then AlphaISelDAGToDAG.cpp:215 for the enforcing of the register constraints (copy into/out of physical registers), then AlphaInsrInfo.td:476 (JSRs) for the call instruction with special register DEF/USE sets to match the calling convention of th...

Hi all, There's been a recent bootstrap failure that might be covered up because of another failure. I just wanted to point this out so that people can take a look: -bw Here's the failure from our buildbot: Assertion failed: (DestReg == VirtReg && "Unknown load situation!"), function RewriteMBB, file /Volumes/Sandbox/Buildbot/llvm/build.llvm-
