SSA MATH: Support COND_LEN_FMA for floating-point math optimization
Hi, Richard and Richi.
Previous patch we support COND_LEN_* binary operations. However, we didn't
support COND_LEN_* ternary.
Now, this patch support COND_LEN_* ternary. Consider this following case:
__attribute__ ((noipa)) void ternop_##TYPE (TYPE *__restrict dst, \
TYPE *__restrict a, \
TYPE *__restrict b,\
TYPE *__restrict c, int n) \
{ \
for (int i = 0; i < n; i++) \
dst[i] += a[i] * b[i]; \
}
TEST_ALL ()
Before this patch:
...
COND_LEN_MUL
COND_LEN_ADD
Afther this patch:
...
COND_LEN_FMA
gcc/ChangeLog:
* genmatch.cc (commutative_op): Add COND_LEN_*
* internal-fn.cc (first_commutative_argument): Ditto.
(CASE): Ditto.
(get_unconditional_internal_fn): Ditto.
(can_interpret_as_conditional_op_p): Ditto.
(internal_fn_len_index): Ditto.
* internal-fn.h (can_interpret_as_conditional_op_p): Ditt.
* tree-ssa-math-opts.cc (convert_mult_to_fma_1): Ditto.
(convert_mult_to_fma): Ditto.
(math_opts_dom_walker::after_dom_children): Ditto.
