[PATCH] D63617: [COFF, ARM64] Fix encoding of __debugbreak

Thu Jun 20 13:18:49 PDT 2019

rnk added a comment.

I think it would be preferable to make `llvm.debugtrap` emit `brk #0xF000` on aarch64-windows-*, so other frontends (Rust etc) get the right behavior by default. Right now, AArch64 doesn't do anything special for DEBUGTRAP, so we get the default behavior of `llvm.trap`.

Is this `BRK #0xF000` convention universal to all OSs, or is it a specific convention for Windows debuggers?
