Subject: Propagator should call value_of_stmt.
X-Git-Tag: basepoints/gcc-14~6072
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5b1594dc2d053803ae98ae39f76fbd71f35cb657;p=thirdparty%2Fgcc.git

Propagator should call value_of_stmt.

When evaluating the LHS of a stmt, its more efficent/better to call
value_of_stmt directly rather than value_of_expr.

	* tree-ssa-propagate.cc (before_dom_children): Call value_of_stmt.
