There was a problem hiding this comment.
You'll want to also add a rerun if env changed directive here.
* Make it influence the behavior of the compiled rustc, rather than just the rustc build system. That is, if verify_llvm_ir=true, even manual invocations of the built rustc will verify LLVM IR. * Enable verification of LLVM IR in CI, for non-deploy and deploy-alt builds. This is similar to how LLVM assertions are handled.

…crum Improve verify_llvm_ir config option LLVM IR verification has been disabled by default in rust-lang#51230. However, the implementation doesn't quite match what was discussed in the discussion. This patch implements two changes: * Make `verify_llvm_ir` influence the behavior of the compiled rustc binary, rather than just the rustc build system. That is, if `verify_llvm_ir=true`, even manual invocations of the built rustc will verify LLVM IR. * Enable verification of LLVM IR in CI, for non-deploy and deploy-alt builds. This is similar to how LLVM assertions are handled.
