gcc11-pr99872.patch

So perhaps this patch?
I went through all ASM_OUTPUT_DEF definitions and all of them use assemble_=
name
for each of the last 2 arguments separately, and assemble_name should handle
the
* etc. at the start of the symbols.
Verified with the cross to mingw -m32 that it now emits .set LC5,LC6, and
verified that on x86_64-linux it didn't change anything e.g. on the testcase
mentioned in the commit message.

I have no way to test this on mingw32, neither 32-bit nor 64-bit, but will =
test
it on x86_64-linux and i686-linux tonight.=
