Thanks to catch this. Look forward to the patch.
I hope this can be resolved in this stable tag.

The mismatch on ASM_PFX seems a big problem.
If we can extend CI to catch it earlier, that would be great.

Thank you

Hi Rebecca,

That does indeed look like a bug for toolchains that prepend the underscore.
Our GSoC student already caught that bug and he's going to submit a patch as soon as possible to fix it.
Mind waiting a few hours? This is a really nice way for him to learn the ropes WRT edk2 patches :)
