a854918f9a * the length of a sequence loading a constant in a register is properly set 
* register contents are fully cleared in clearregcontentsfrom()

00f401693c * fixed web bug #5094. Renaming registers is now done sequentially instead 
of all at the same time, because otherwise circular renamings could
    cause errors

a1b2701e5f * if while we are restoring the contents of a register, we encounter an 
operation which changes a register, clear the contents of all registers
    which depend on this register

4b887ef604 * when restoring a register's previous contents after it's been replaced 
completely, there were some missing checks to make certain these
    previous contents didn't conflict with memory operations in the new
    sequence

af36d177d9 * if we find a constant already loaded in a register and we use that 
register, mark the register as read by the current instruction
    (fixes compilation of tcalfun8 with optimizations)

c3a5f88a7b * fixed webtbs/tw4388: properly process regalloc info coming right after 
a tai_marker of type asmblockend, and fixed removal of too many
    tai_regallocs in some cases (daopt386.pas)
  * some preventive fixes to make sure the optimizer doesn't start optimizing
    inside inline assembler blocks (csopt386.pas)

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)

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
