[llvm-dev] Reviewer, with WebAssembly knowledge, requested for D78778

[Venkata Ramanaiah Nalamothu via llvm-dev]

Hi,

I have put together a patch https://reviews.llvm.org/D78778 for the AsmPrinter.

It aims at being able to emit the CFI unwind information for debugging
purposes as needed when exceptions are not enabled/supported.
Currently no CFI unwind information will be emitted if
`MCAsmInfo::getExceptionHandlingType() == ExceptionHandling::None`,
even if `--force-dwarf-frame-section` is used.

Due to this patch, llvm/test/MC/WebAssembly/{debug-info.ll,
debug-info64.ll} needed updates to accommodate the .debug_frame
section that is being generated now.

While the outcome of the patch is in the right direction, I am
wondering if someone could review if the updates to WebAssembly LIT
tests are expected?

Thanks,
Ram
