Wasmtime GitHub notifications bot (Oct 16 2020 at 00:03):

fitzgen opened PR #2293 from souper-no-assign-constant to main:

It turns out that Souper does not allow a constant to be assigned to a variable,
they may only be used as operands. The 2.0.0 version of the souper-ir crate
correctly reflects this. In the cranelift_codegen::souper_harvest module, we
need to modify our Souper IR harvester so that it delays converting iconst and
bconst into Souper IR until their values are used as operands. Finally, some
unit tests in the peepmatic-souper crate need some small updates as well.

@iximeow could you take a look at this? Thanks!
