Fix too narrow loads while unspilling#66675
Conversation
Unspilling could produce too narrow loads for normalize-on-load variables when encountering a narrowly typed LCL_VAR node. This could result in subsequent uses of the same local using a truncated value. Fix dotnet#66624

FWIW, it seems likely to me that we could always use 'wide' loads here, at least on non-ARM. We already do so for dependently promoted small fields (even unaligned) and when enregistering incoming stack args, so clearly these rely on upstream code to have inserted casts. However I preferred the smaller set of diffs here. |
