Last change on this file since 513 was 445, checked in by krille_n_@…, 12 years ago

Changes:

  • A speed optimization to the eSHL_IM macro for 386 and higher. This change breaks emulation in the sense that the macro will fail when given a memory operand as the first parameter.
  • Memory_SumCXbytesFromESSItoAL now returns with the zero flag set/cleared according to the result.
  • Unrolled all the 8 bit READ transfer loops to do 16 bytes per iteration. Added a new macro (UNROLL_SECTORS_IN_CX_TO_OWORDS) as part of it. Size wise this is expensive but I think it should be worth the ROM space. The WRITE transfer loops were left as is since writes are rare anyway (<10% of all disk I/O IIRC).
  • Minor optimizations and fixes here and there.
