Incorrect Assembly of certain numbers

[Electronics]

#align 24
JNZ {check_addr}, {branch_addr} -> 6'0x04 @ check_addr[4:0] @ 5'0 @ branch_addr[7:0]

will produce f***** whatever the input when it should be 1*****. By changing the above to

#align 24
JNZ {check_addr}, {branch_addr} -> 6'0x04 @ 18'0x00

it works correctly. Seems to be something to do with the alignment and how it concatenates bits together.

Wow, good catch! I've fixed it, it's in the dev branch.

Did you download from Releases or compile it yourself? Just please be warned that I've been changing some syntax in the dev branch; docs are still incomplete.

Let me know if you need anything! I'd love to know what you're working on.

That was from the releases, I'm working on an assignment at the moment to produce a FPGA-synthesisable picoMIPS processor capable of the affline transformation. I've got it all working now and this assembler has been so useful in programming the thing!

I've added a new release which includes this fix!

If you try it out, could you please let me know if the new way to define a CPU helps? I'm afraid it might be more cumbersome in some cases...

And that is an awesome project you're working on! If possible, keep me updated. We should chat! 😜
