From 23756db02e8d8337075b377408af5093c0401de2 Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Fri, 15 Jan 2021 17:08:55 +0100 Subject: fix type of canonicalization of sext + unsigned compare In commit 4a5f616407e2 ("cmp: canonicalize sext(x) cmpu C (with C >= SMAX)"), the operand is replaced to avoid a sign extension but the corresponding type was not updated. Fix this now.
