Remove copysign post_reload splitter for scalar modes.
It can generate better code just like avx512dq-abs-copysign-1.c
shows.
gcc/ChangeLog:
* config/i386/i386-expand.c (ix86_expand_copysign): Expand
right into ANDNOT + AND + IOR, using paradoxical subregs.
(ix86_split_copysign_const): Remove.
(ix86_split_copysign_var): Ditto.
* config/i386/i386-protos.h (ix86_split_copysign_const): Dotto.
(ix86_split_copysign_var): Ditto.
* config/i386/i386.md (@copysign<mode>3_const): Ditto.
(@copysign<mode>3_var): Ditto.
gcc/testsuite/ChangeLog:
* gcc.target/i386/avx512dq-abs-copysign-1.c: Adjust testcase.
