tree-optimization/110451 - hoist invariant compare after interchange
The following adjusts the cost model of invariant motion to consider
[VEC_]COND_EXPRs and comparisons producing a data value as expensive.
For 503.bwaves_r this avoids an unnecessarily high vectorization
factor because of an integer comparison besides data operations on
double.
PR tree-optimization/110451
* tree-ssa-loop-im.cc (stmt_cost): [VEC_]COND_EXPR and
tcc_comparison are expensive.
* gfortran.dg/vect/pr110451.f: New testcase.
