In addition to Daniel's reply: you wouldn't want to use "r" here.
That's for general registers only.
The MIPS port does in theory support coprocessors, but the functionality
isn't tested much (if at all). The c
Thanks Daniel!
actually my 2 messages were send back-to-back. I have just read both your
responses and I can see that i could use stringify approach to force the
assembly output of GCC to what I want.

I was wondering...
why not support asm templates THAT ARE NOT string constants??? And I
mean for static compilation cases only.
For example:
asm(instrx $%d, $%d\n",src1,src2 : "=r" (var1) : "r" (var2));
I assume printf-like formating.
Or else you may need either write a double-nested switch (a
Hi guys/ladies,
I'm currently designing an ISA add-on to the MIPS architecture. My
intention is to use it (it is an algorithm accelerator actually) as a
COP2 (coprocessor #2). The corresponding microarchitecture is stable
(works at register-transfer level, not subject to change). Plus, I
