re PR tree-optimization/87546 (Gcc miscompiles at -O3 on valid code)
PR tree-optimization/87546
* tree-vect-patterns.c (vect_look_through_possible_promotion): Add
min_precision variable, initially set it to orig_precision, only does
something if op_type's precision is <= min_precision and update
min_precision whenever calling set_op.
* gcc.dg/vect/O3-pr87546.c: New test.
From-SVN: r266237
