There's also the issue that to fully support inlining, you have to be 
able to store the entire procedure body in the ppu file. And there is no 
support to do this for assembler code at this time (the skeleton exists, 
but that's it).

Regarding the used registers and parameters, I would still forbid 
inlining for pure assembler routines, and only allow it for regular 
procedures with assembler blocks. That way the compiler would have full 
control over where the parameters and return value are stored etc. Doing 
it for pure assembler routines creates a whole lot of extra problems 
with potentially worse code quality in the end, because the compiler has 
much less freedom.
