Wasmtime GitHub notifications bot (Dec 04 2020 at 17:41):

julian-seward1 opened PR #2478 from fix-collect-address-addends to main:

…TW(negative immediate)`.

The current code doesn't correctly handle the case where ExtendOp::UXTW has
as source, a constant-producing insn that produces a negative (32-bit) value.
Then the value is incorrectly sign-extended to 64 bits (in fact, this has
already been done by ctx.get_constant(insn)), whereas it needs to be zero
extended. The obvious fix, done here, is just to force bits 63:32 of the
extension to zero, hence zero-extending it.
