+ ; CHECK-DAG: [[SEXT1:%[0-9]+]]:_(s32) = G_SHL [[COPY]], [[I25]]
+ ; This constant is coming from a custom legalization for G_ASHR rather than G_SEXT_INREG lowering
+ ; CHECK-DAG: [[I25_64:%[0-9]+]]:_(s64) = G_CONSTANT i64 25
+ ; CHECK-DAG: [[SEXT2:%[0-9]+]]:_(s32) = G_ASHR [[SEXT1]], [[I25_64]]
----------------
@paquette @aemerson: I ought to draw attention to this. My code appears to be doing the right thing for lower() of G_SEXT_INREG but you appear to have a custom legalization that promotes one of the two constants to s64. Is that intentional? If so, is it also intentional that it only does it for G_ASHR and not G_SHL too?
