[Assignment 5] Hazardflow panics if I try to use pe from assignment 4

[JustinKim98]

in implementation of tile_with_reg function in assignment 5, the default implementation given uses tile function defined in tile.rs which uses pe implemented outside.

However, if I try to change pe_ffi to pe which I implemented on assignment 4, hazardflow panics during the build process. (I passed all tests given in assignment 4)

Is this an expected behavior? If it is, should we use pe_ffi instead pe for assignment 5? (My implementation in assignment 5 passes tests if I use pe_ffi)

Oh, yes! It was intended to use pe_ffi, we use the original Gemmini PE implementation in the Assignment 5.

FYI: The reason of the panic is due to the #[synthesize] attribute in the PE function, the hazardflow compiler currently panic if that attribute is in a function which is not a top module.
