Error: Unsupported instruction

[hakukohaku]

I want to simulate the flashattention_2 in pulp_platform/snitch_cluster/sw/dnn by banshee, but the following error was encountered:

ERROR banshee::tran > Unsupported instruction 0x800027b8: <illegal 0xf60b80d3>
ERROR banshee::tran > Unsupported instruction 0x800027c0: <illegal 0xe6010bd3>
ERROR banshee::tran > Unsupported instruction 0x800027e0: <illegal 0xf60c01d3>
......
All these instructions are fmv.b.x or fmv.x.b. Does banshee support them? Or how to resolve this error?

Banshee currently doesn't support those operations. It only supports the word and half-word versions at the moment: https://github.com/pulp-platform/banshee/blob/main/src/tran.rs#L3254
