Wasmtime GitHub notifications bot (Aug 23 2023 at 14:43):saulecabrera opened PR #6891 from saulecabrera:winch-use-type-information-for-sizes to bytecodealliance:main:
This change is a small refactor to how we've been handling the operand size
parameter passed to some of theCodeGenContextoperations, namely,
pop_to_regandmove_val_to_reg.Given the more precise value tagging introduced in:
https://github.com/bytecodealliance/wasmtime/pull/6860,
it's now possible to derive the operand size from the type associated to a value
stack entry, which:
- Makes the usage of the functions mentioned above less error prone.
- Allows a simplification of the two function definitions mentioned above.
- Results in better instruction selection in some cases.

This is a nice simplification, thanks! It's nice to see that some x86 code gets a little more compact too without the REX prefixes (because 32-bit moves can be used).
