[armv7l] llc crash in llvm::ARMAsmPrinter::emitXXStructor #170017
Description
I found this crash while cross-compiling ghc for armv7l-linux on an x86_64-linux host. The nixpkgs issue is NixOS/nixpkgs#466116.
Reproduction steps:
- Install Nix
- Check out nixpkgs at latest
master nix build .#pkgsCross.armv7l-hf-multiplatform.buildPackages.ghc
Alternatively, to get a shell in the build environment:
- Install Nix
- Check out nixpkgs at latest
master mkdir build && cd buildnix develop .#pkgsCross.armv7l-hf-multiplatform.buildPackages.ghcgenericBuild
The build will keep going after the failure, so scroll up to find the crash. You can then re-run the failing command with different arguments.
Here is the build log output:
