Hmm, that's very unfortunate. I don't really understand why the

Just spit balling, but is there a reason we didn't just put the macros
for inline assembly directly in the header? Something like this:
asm(".macro ANNOTATE_UNREACHABLE counter:req\n\t"
"\\counter:\n\t"
"

I tested it to be sure -- but, no, this does not have any affect on

I'm not sure how much we care about this or what we can do about it, but
adding the macros.s to the command line like this has effe

Using macros for inline assembly improves both readability and
compilation decisions that are distorted by big assembly blocks that use
alternative sections. Compile macros.S and use it to assemble all C
files. Currently, only x86 will use it.
