re PR tree-optimization/54295 (Widening multiply-accumulate operation uses wrong value extension)
PR tree-ssa/54295
* tree-ssa-math-opts.c (widening_mult_conversion_strippable_p):
Sign-extension of a zero-extended value can be simplified to
just zero-extension.
testsuite:
* gcc.target/arm/pr50318-1.c: Scan for smlal.
* gcc.target/arm/smlaltb-1.c: XFAIL test.
* gcc.target/arm/smlaltt-1.c: Likewise.
