Failing IR
I was recently trying to upgrade LLVM in rust-lang/rust but hit some bugs when
testing a community crate on the wasm backend. Specifically if the compiled IR
is attached and validated it fails to validate:
$ llc foo.ll-O2 -filetype=obj -o foo.o
$ wasm2wat foo.o
foo.o:0000086: error: type mismatch in i32.eqz, expected [i32] but got []
foo.o:00000a0: error: type mismatch in function, expected [] but got [i32]
