gcc : ChangeLog optabs.c
Log message:
PR 19696
* optabs.c (expand_absneg_bit): Split out from expand_unop and
expand_abs_nojump and generalize. Use operand_subword and
emit_no_conflict_block. Support large modes.
(expand_abs_nojump): Use it. Use HONOR_SIGNED_ZEROS to fall
back to maximum.
(expand_unop): Likewise. Use HONOR_SIGNED_ZEROS to fall back
negation to subtraction.
(expand_copysign): Check that the format has signed zeros.
Use operand_subword and emit_no_conflict_block. Support large modes.
