[Patch i386] PR78509 - TARGET_C_EXCESS_PRECISION should not return
"unpredictable" for EXCESS_PRECISION_TYPE_STANDARD
gcc/
PR target/78509
* config/i386/i386.c (i386_excess_precision): Do not return
FLT_EVAL_METHOD_UNPREDICTABLE when "type" is
EXCESS_PRECISION_TYPE_STANDARD.
* target.def (excess_precision): Document that targets should
not return FLT_EVAL_METHOD_UNPREDICTABLE when "type" is
EXCESS_PRECISION_TYPE_STANDARD or EXCESS_PRECISION_TYPE_FAST.
Fix typo in first sentence.
* doc/tm.texi: Regenerate.
