[Bug target/102224] [12 regession] wrong code for `x * copysign(1.0, x)`
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102224 --- Comment #5 from Gabriel Ravier --- Actually it seems to me like this is a GCC 9 regression, ever since this pattern exists: GCC 9, 10 and 11 emit the exact same faulty code.
