Move pass_cse_sincos after vectorizer.
__builtin_cexpi can't be vectorized since there's gap between it and
vectorized sincos version(In libmvec, it passes a double and two
double pointer and returns nothing.) And it will lose some
vectorization opportunity if sin & cos are optimized to cexpi before
vectorizer.
I'm trying to add vect_recog_cexpi_pattern to split cexpi to sin and
cos, but it failed vectorizable_simd_clone_call since NULL is returned
by cgraph_node::get (fndecl). So alternatively, the patch try to move
pass_cse_sincos after vectorizer, just before pas_cse_reciprocals.
Also original pass_cse_sincos additionaly expands pow&cabs, this patch
split that part into a separate pass named pass_expand_powcabs which
remains the old pass position.
gcc/ChangeLog:
* passes.def: (Split pass_cse_sincos to pass_expand_powcabs
and pass_cse_sincos, and move pass_cse_sincos after vectorizer).
* timevar.def (TV_TREE_POWCABS): New timevar.
* tree-pass.h (make_pass_expand_powcabs): Split from pass_cse_sincos.
* tree-ssa-math-opts.cc (gimple_expand_builtin_cabs): Ditto.
(class pass_expand_powcabs): Ditto.
(pass_expand_powcabs::execute): Ditto.
(make_pass_expand_powcabs): Ditto.
(pass_cse_sincos::execute): Remove pow/cabs expand part.
(make_pass_cse_sincos): Ditto.
gcc/testsuite/ChangeLog:
* gcc.dg/pow-sqrt-synth-1.c: Adjust testcase.
