rs6000: Make copysign (x, -1) back to -abs (x) for IEEE128 float [PR112606]
I noticed that commit r14-6192 can't help PR112606 #c3 as
it only takes care of SF/DF but TF/KF can still suffer the
issue. Similar to commit r14-6192, this patch is to take
care of copysign<mode>3 with IEEE128 as well.
PR target/112606
gcc/ChangeLog:
* config/rs6000/rs6000.md (copysign<mode>3 IEEE128): Change predicate
of the last argument from altivec_register_operand to any_operand. If
operands[2] is CONST_DOUBLE, emit abs or neg abs depending on its sign
otherwise if it doesn't satisfy altivec_register_operand, force it to
REG using copy_to_mode_reg.
