Michael Munday ddf807fce8 cmd/compile: fix type propagation through s390x SSA rules ... This CL fixes two issues: 1. Load ops were initially always lowered to unsigned loads, even for signed types. This was fine by itself however LoadReg ops (used to re-load spilled values) were lowered to signed loads for signed types. This meant that spills could invalidate optimizations that assumed the original unsigned load. 2. Types were not always being maintained correctly through rules designed to eliminate unnecessary zero and sign extensions. Fixes #18906.
