@vertigo If you need something special, let me know, I am happy to help with pointers for porting Mecrisp-Quintus. Congrats to your own processor design, one of the two FemtoRV32 authors here :-) By the way, which instruction set extensions have you implemented?

@Mecrisp Currently, I'm strictly RV64I - nothing else.
I'm in the process of working on an update of the core as I type this; I'd like to add proper pipelining, plus support for the (ill-specified) M-extension at a later point in time. Support for the C-extension would be nice, but it will need to wait until I finish up with other tasks first.

@vertigo I see, the Forth core itself has support for RV64I, with code for software multiplication and division one can activate using an assembler switch. It passes the test suite, but I have not released a target using that.

@Mecrisp Nice; I'm assuming the code is written to use GNU as syntax?

@vertigo True.
