Description

Hi,

I'm running Binaryen with -S (because I'm using a combination of proposals not handled by other tools yet) in order to debug some code. I added the --intrinsic-lowering flag, hoping it would remove the tuples and use locals or whatever instead but it seems this is not the case.

Is there a way to get rid of them in the text format generated by Binaryen? Binaryen is able to produce a binary file so what I'd like is to get the equivalent text format.

This is related to #6016 but it's really not helping me.

Thanks!

Research direction

Start by reproducing the issue with Binaryen's -S and --intrinsic-lowering flags, and read the discussion in #6016 for related context. Trace the text-output path and intrinsic-lowering entry point; done means the generated text no longer contains tuple instructions while remaining equivalent to the produced binary.
