i386: Improve vector mode and TFmode ABS and NEG patterns
gcc/ChangeLog:
2020-05-18 Uroš Bizjak <ubizjak@gmail.com>
* config/i386/i386-expand.c (ix86_expand_fp_absneg_operator):
Do not emit FLAGS_REG clobber for TFmode.
* config/i386/i386.md (*<code>tf2_1): Rewrite as
define_insn_and_split. Mark operands 1 and 2 commutative.
(*nabstf2_1): Ditto.
(absneg SSE splitter): Use MODEF mode iterator instead of SSEMODEF.
Do not swap memory operands. Simplify RTX generation.
(neg abs SSE splitter): Ditto.
* config/i386/sse.md (*<code><mode>2): Mark operands 1 and 2
commutative. Do not swap operands. Simplify RTX generation.
(*nabs<mode>2): Ditto.
