I ran the preprocessed code through cvise[1], bisecting for a reduced
test case that fails on gcc-8 but succeeds on gcc-9. The reduced
case is still fairly complex, and it appears to only happen in the
presence of an inline asm. Narrowing down the compiler versions shows
that anything after gcc-9.2 does not warn, but 9.1 and earlier versions do,
which is further indication that it was probably a false-positive that got
fixed in gcc.
Thanks for investigating! So let's ignore this.
FTR, my gcc-9 is 9.4.0, i.e. >= 9.2.
Ok, if it comes up again, I suppose we can make the warning conditional on
the compiler warning.
