[Tinycc-devel] looking for documentation for porting

[Michael Larson]

Hello,

I have been tinkering around with TCC porting to a RISC cpu of my own
design, I have my own C simulator and verilog targeted for a FPGA.. I
have a lot of tests for functionality, but I need more so TCC looked
like a good option to generate code for.

I have been following some of the code samples given like the C67 and
MIPS source, I have about half of it done but documentation on how
this works seems to be really missing.

I did a normal port, I copied all the functions out of the header
files required and built a C file for them. This worked well... but..
there are a lot of questions.

Like

int gjmp_cond(int op, int t)

I look around the source and see a bunch of different implementations
of this, but there is no documentation on how it's supposed to work? I
am sure I could dig into it a bit more.. but it's time to ask where
the documentation is, maybe I am missing something.. is there
documentation out there?

I only have a few functions left so I am not going to give up at this point.

Thanks ahead of time,

Mike
