ea6529ff63 * manually merged merge request 69 by J. Gareth "Kit" Moreton: 
x86: CMP/MOV refactoring and expansion
      This merge request refactors the SwapMovCmp routine, and calls to it, to be more self-contained,
      having the preliminary checks built-in to ensure that moving the MOV instruction is
      actually a sound idea, while also making it more general-purpose so it can handle instructions
      that are not MOV operations. This feature is primarily for future expansion,
      but also cleans up the code for the x86 peephole optimizer.

4012c3dbd4 * merge request 75 by J. Gareth "Kit" Moreton manually applied: 
This merge request makes a number of improvements to the DeepMOVOpt method and supporting functions:

      * ReplaceRegisterInInstruction now replaces registers in references that are written to
        (since the registers themselves won't change)
      * RegModifiedByInstruction will no longer return True for a register that appears in a reference
        that's written to (for the same reason as above) - special operations like MOVSS
        (the 0-operand version) aren't affected.
      * DeepMOVOpt returning True will now always set the Result of OptPass1MOV to True even though p
        wasn't directly modified, since this often caused missed optimisations.
      * Some of the speed-ups in the patch from #32916 have also been applied in order to make
        the general DeepMOVOpt run faster, notably it tries to avoid calling UpdateUsedRegs where possible.

d55b2c2a35 + extend assembler optimization MovxMov2Mov to MovxOp2Op 2021-10-15 23:12:59 +02:00
Nikolay Nikolov
21d843128d + added a wrapper function around __wasi_path_readlink that calls it iteratively 
with doubling buffer sizes, starting with 64 bytes, until it reaches 16384
  bytes, and reads the link into a rawbytestring. Use that function in all
  places in the WASI rtl that need to read a symlink.
