      Resolve floating point exception with frame_init_lowres mmx · 65324952
      Fiona Glaser authored
      In some cases, the mmx version of frame_init_lowres could leave the FPU uninitialized for use in ratecontrol, resulting in floating point exceptions.
      Since frame_init_lowres is such a time-consuming function, an emms was just put at the end, since it costs almost nothing compared to the total time of frame_init_lowres.

      lowres_init asm · 04dc2536
      Loren Merritt authored
      rounding is changed for asm convenience. this makes the c version slower, but there's no way around that if all the implementations are to have the same results.

      Move bitstream end check to macroblock level · e9369576
      Fiona Glaser authored
      Additionally, instead of silently truncating the frame upon reaching the end of the buffer, reallocate a larger buffer instead.

      Convert NNZ to raster order and other optimizations · ec3d0955
      Fiona Glaser authored
      Converting NNZ to raster order simplifies a lot of the load/store code and allows more use of write-combining.
      More use of write-combining throughout load/save code in common/macroblock.c
      GCC has aliasing issues in the case of stores to 8-bit heap-allocated arrays; dereferencing the pointer once avoids this problem and significantly increases performance.
      More manual loop unrolling and such.
      Move all packXtoY functions to macroblock.h so any function can use them.
      Add pack8to32.
      Minor optimizations to encoder/macroblock.c

      Add more inline asm and a runtime check for MMXEXT support · 2a7dd58c
      Fiona Glaser authored
      x264 will now terminate gracefully rather than SIGILL when run on a machine with no MMXEXT support.
      A configure option is now available to build x264 without assembly support for support on such old CPUs as the Pentium 2, K6, etc.

      Cosmetics and loop unrolling · dba0e5a2
      Fiona Glaser authored
      GCC is not very good at loop unrolling in cases where it can perform constant propagation, so the unrolling unfortunately has to be done manually.
