- Subject: [4.4] Fix PR rtl-optimization/46337
This fixes an embarrassing bug in dse.c: arguments passed to gen_int_mode are
swapped in a couple of places. This was already fixed on the 4.5 branch
(then mainline) by Ian; the submitter ran into it on the 4.4 branch as well.
Tested on i586-suse-linux, applied on the 4.4 branch.
