dmd.backend.cod3.movregconst - multiple declarations

Function movregconst

Move constant value into reg. Take advantage of existing values in registers. If flags & mPSW set flags based on result Else if flags & 8 do not disturb flags Else don't care about flags If flags & 1 then byte move If flags & 2 then short move (for I32 and I64) If flags & 4 then don't disturb unused portion of register If flags & 16 then reg is a byte register AL..BH If flags & 64 (0x40) then 64 bit move (I64 only)

extern(C++) void movregconst (
  ref dmd.backend.code.CodeBuilder cdb,
  uint reg,
  ulong value,
  uint flags
);

Returns

code (if any) generated
