[Qemu-devel] [PATCH 0/4] tcg memory usage improvements

While continuing to work on the sparc64 on i686 problem, I've run into
a few things that could be done better.

I haven't done any proper measurements of memory usage or boot time,
but all together my guess is that this saves 10-20k.  Not much, I grant,
but maintaining more cache locality ought not hurt.


Richard Henderson (4):
  tcg: Compress liveness data to 16 bits
  tcg: Reorg TCGOp chaining
  tcg: Fold life data into TCGOp
  tcg: Compress dead_temps and mem_temps into a single array
