Commit Message

Adhemerval Zanella Netto Nov. 7, 2024, 11:22 a.m. UTC 
The commit 9247f53219 triggered some regressions on loongarch and
riscv:

math/test-float-log10
math/test-float32-log10

And it is due a wrong sync with CORE-MATH for special 0.0/-0.0
inputs.

Checked on aarch64-linux-gnu and loongarch64-linux-gnu-lp64d.
