Doing 9p over USB is interesting, though I would have considered u

For the most part it's a straightforward RISC.
Might do the disassembler next to help debug the rest, and finally the

Thanks for the diagnosis. I'll dig into the p
I'm using the Inferno Thumb compiler, tc, to compile Inferno (unsurprisingly)
and encountered a problem. Since 9front appears to have the same compiler, I
thought that I should mention it on both 9fans and Inferno mailing lists.
The problem is with the libmath/fdlibm/e_exp.c when compiled using tc

However, it basically boils down to this:
