Subject: Use a boolean type when folding conditionals in simplify_using_ranges.
X-Git-Tag: basepoints/gcc-16~8980
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f6bed6d3fcc13880ffa786b6c616e2306efe2bf3;p=thirdparty%2Fgcc.git

Use a boolean type when folding conditionals in simplify_using_ranges.

In adding some traps for PR114985 I noticed that the conditional
folding code in simplify_using_ranges was using the wrong type.  This
cleans up the oversight.

gcc/ChangeLog:

	PR tree-optimization/114985
	* vr-values.cc (simplify_using_ranges::fold_cond_with_ops): Use
	boolean type when folding conditionals.
