[PATCH] tree-optimization/101254 - Fix MINUS_EXPR relations.
Tue Jun 29 19:10:18 GMT 2021
We were incorrectly calculating the LHS of a MINUS_EXPR for wrapping
signed values. This patch cleans that up and fully fleshed out the
possible LHS of OP1 - OP2 given a known relation between them.
Bootstraps on x86_64-pc-linux-gnu with no regressions. Pushed.
