Function allocreg
Allocate some registers.
extern(C++) void allocreg
(
ref dmd .backend .code .CodeBuilder cdb,
uint* pretregs,
uint* preg,
uint tym
);
Input
pretregs Pointer to mask of registers to make selection from. tym Mask of type we will store in registers.
Output
*pretregs Mask of allocated registers. *preg Register number of first allocated register. msavereg,mfuncreg retregs bits are cleared. regcon.cse.mval,regcon.cse.mops updated
Returns
pointer to code generated if necessary to save any regcon.cse.mops on the stack.
