Hello,
Can anyone translate me this 68k code into C (or ppc asm..)
The first one seems a simply shift? or i ame wrong?
putreg(REG_D1, 0); do { *bw = *(UWORD *)((UBYTE *)*plane-- + offset) >> shift; putreg(REG_A0, (long)bw); __emit(0xE4D0); /* ROXR.W (A0) */ __emit(0xE351); /* ROXL.W #1,D1 */ ++bw; } while (--d > 0);
