Subject: Limit ranger query in ipa-prop.cc to integrals.
X-Git-Tag: basepoints/gcc-14~5276
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e9f5b4fa4f2c93ef76e3766b3edabfaebc100741;p=thirdparty%2Fgcc.git

Limit ranger query in ipa-prop.cc to integrals.

ipa-* still works on legacy value_range's which only support
integrals.  This patch limits the query to integrals, as to not get a
floating point range that can't exist in an irange.

gcc/ChangeLog:

	* ipa-prop.cc (ipa_compute_jump_functions_for_edge): Limit ranger
	query to integrals.
