I'm thinking of virtual registers here... ie
if sizeof(INTVAL) == 4
'L' is a PMC
else if sizeof(INTVAL) == 8
'L' is an INTVAL
So 64 bit opcodes are compiled in differently for each platform ?
ie add a set of virtual 'L' registers which turn into 32 new PMC regs
in 32 bit and 32 new INTVALs in 64 bit systems ?
To take away the choice deep down into the JIT compile time ?
(actually "when the JIT is compiled" time :-)
Since due to an accident , we have conv_i8 as an opcode and not as an
explicit PMC call , we should be able to #ifdef it's internals to match
the hardware ?. This should hard-code it after compilation with none of
the runtime overhead.
After all we saw lots of C compilers do something similar for floats :-)
