      x86: swscale: fix fragile memory accesses · 90540c2d
      Mans Rullgard authored
      To access data at multiple fixed offsets from a base address, this
      code uses a single "m" operand and code of the form "32%0", relying on
      the memory operand instantiation having no displacement, giving a final
      result of the form "32(%rax)".  If the compiler uses a register and
      displacement, e.g. "64(%rax)", the end result becomes "3264(%rax)",
      which obviously does not work.
      
      Replacing the "m" operands with "r" operands allows safe addition of a
      displacement.  In theory, multiple memory operands could use a shared
      base register with different index registers, "(%rax,%rbx)", potentially
      making more efficient use of registers.  In the cases at hand, no such
      sharing is possible since the addresses involved are entirely unrelated.
      
      After this change, the code somewhat rudely accesses memory without
      using a corresponding memory operand, which in some cases can lead to
      unwanted "optimisations" of surrounding code.  However, the original
      code also accesses memory not covered by a memory operand, so this is
      not adding any defect not already present.  It is also hightly unlikely
      that any such optimisations could be performed here since the memory
      locations in questions are not accessed elsewhere in the same functions.
      
      This fixes crashes with suncc.

      This code has been disabled since 2003.  Nobody will ever look at
      it again.

      x86: build: replace mmx2 by mmxext · 239fdf1b
      Diego Biurrun authored
      Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
      So switching to a consistent naming scheme beforehand is sensible.
      The name "mmxext" is more official and widespread and also the name
      of the CPU flag, as reported e.g. by the Linux kernel.
