02beda1221 This is the real fix for the previous register allocator problem.
Physical registers should not float around.

0bfd186db0 Add patterns for (mov R, R) (mov R, I) and subtracts. The moves are to enable
testing, the subtracts are because I was in the neighborhood.

a328f887c7 * Don't print out HOW we are running Flex unless in verbose mode. We already
hide the bison command line.
* If running flex or bison gives us the files we already have, don't overwrite
  the ones we have, which cause unnecessary compilation.  I demand the ability
  to make meaningless changes without penalty!

e012132028 * Sort #includes, remove dupliates
* Use .zero to emit padding between struct elements
* Emit .comm symbols when we can, this dramatically reduces the amount of gunk we have to print
* Print global variable identifiers next to initializer more nicely.
