Subject: Avoid shift in get_ref_base_and_extent
X-Git-Tag: basepoints/gcc-14~6408
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=37c988bc1b22d1259a4d8e819fc33c65faa9debb;p=thirdparty%2Fgcc.git

Avoid shift in get_ref_base_and_extent

This avoids one instance of a shift from bytes to bits in
get_ref_base_and_extent by using TYPE_SIZE instead of TYPE_SIZE_UNIT.

	* tree-dfa.cc (get_ref_base_and_extent): Avoid shift.
