Subject: tree-ssa-math-opts: Use element_precision.
X-Git-Tag: basepoints/gcc-15~7951
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=16e4f09a594f801f68eb0a3e35d1c6e60d402b64;p=thirdparty%2Fgcc.git

tree-ssa-math-opts: Use element_precision.

The recent TYPE_PRECISION changes to detect improper usage
cause an ICE in divmod_candidate_p for RVV when called with
a vector type.  Therefore, use element_precision instead.

gcc/ChangeLog:

	* tree-ssa-math-opts.cc (divmod_candidate_p): Use
	element_precision.
