tree-optimization/118529 - ICE with condition vectorization
On sparc we end up choosing vector(8) <signed-boolean:1> for the
condition but vector(2) int for the value of a COND_EXPR but we
fail to verify their shapes match and thus things go downhill.
This is a missed-optimization on the pattern recognition side
as well as unhandled vector decomposition in vectorizable_condition.
The following plugs just the observed ICE for now.
PR tree-optimization/118529
* tree-vect-stmts.cc (vectorizable_condition): Check the
shape of the vector and condition vector type are compatible.
* gcc.target/sparc/pr118529.c: New testcase.
