parameter passing for functions written in assembly.

[vijay nag]

GCC-Veterans,

I've written hand-written assembly for couple of commonly used
function in my module with an intent of having a very highly optimized
version of the same taking into consideration cache, process
cache-lines et al.  I'm not an ABI expert and I wanted to know the
calling convention usually followed to pass the parameters in register
to the function ? How to let the GCC know what function parameter have
to be passed in a specific register ?


Thanks,
Vijay Nag
