Hi Richard,
your patch fails here; I get the build failure:
/projects/tob/gcc-git/gcc/gcc/tree-ssa-math-opts.c: In function ‘bool
is_widening_mult_rhs_p(tree, tree, tree_node**, tree_node**)’:
/projects/tob/gcc-git/gcc/gcc/tree-ssa-math-opts.c:2014:18: error:
variable ‘rhs_code’ set but not used [-Werror=unused-but-set-variable]
enum tree_code rhs_code;
