yet though

84aa52942f * fixed tracking of usage of flags register 
* fixed destroying of "memwrite"'s
  * fixed checking of entire sequences in all cases (previously this was
    only guaranteed if the new sequence was longer than the old one, and
    not if vice versa)
  * fixed wrong removal of sequences if a register load was already
    completely removed in the previous sequence (because in that case,
    that register has to be removed and renamed in the new sequence as
    well before removing the new sequence)

ee3585f56f * spilling code rewritten for x86. It now used the generic 
spilling routines. Special x86 optimization still needs
    to be added.
  * Spilling fixed when both operands needed to be spilled
  * Cleanup of spilling routine, do_spill_readwritten removed

6abc491796 - disable removal of dead loads before a call, because register 
parameters are released before a call
  * fix storeback of registers in case of different sizes (e.g., first
    a "movl %eax,%edx" and later a "movb %dl,%al")

942cfc9aac * isgp32reg was being called with both tsuperregister and tregister 
parameters, so changed type to tsuperregister (fixes bug reported by
    Bas Steendijk)
  * improved regsizesok() checking so it gives no false positives anymore

aad37ce53c * fixed optimiser so it compiles again 
* fixed several bugs which were in there already for a long time, but
    which only popped up now :) -O2/-O3 will now optimise less than in
    the past (and correctly so), but -O2u/-O3u will optimise a bit more
  * some more small improvements for -O3 are still possible
