Compiler gets stuck in Infinite (so far) loop about zig HOT 4 CLOSED

this isnt reproducing for me locally on 0.13.0-dev.201+86d8688c7. fixed in the llvm 18 upgrade maybe?

from zig.

Indeed, this spits out an LLVM assertion on my pre-LLVM18 build:

LLVM Emit Object... zig: /home/mlugg/llvm17/llvm/lib/CodeGen/SelectionDAG/LegalizeDAG.cpp:982: void {anonymous}::SelectionDAGLegalize::LegalizeOp(llvm::SDNode*): Assertion `(TLI.getTypeAction(*DAG.getContext(), Op.getValueType()) == TargetLowering::TypeLegal || Op.getOpcode() == ISD::TargetConstant || Op.getOpcode() == ISD::Register) && "Unexpected illegal type!"' failed.

I'm willing to bet this was indeed fixed with the LLVM 18 upgrade, but to be sure, I will wait for someone with a debug build of a post-LLVM18 compiler to confirm that no assertion is tripped.

from zig.

that's a dupe: andrew filed llvm/llvm-project#90356 and fixed in 18.1.x

confirmed:

• zig 0.12.0 w/ llvm-17.0.6 release+assert trips assertion
• zig 0.12.0 w/ llvm-17.0.6 release spins infinite
• zig master w/ llvm-18.1.5 release+assert does not trip assertion (builds object)
• zig master w/ llvm-18.1.5 release builds object

from zig.

Cool!
