Polina Dudnik 226981b2a6 Reintegrated Derek's functional implementation of atomics with a minor change: don't clear lock on failure 2009-07-13 11:13:29 -05:00
Gabe Black 60577eb4ca ISAs: Get rid of the IControl operand type. 
A separate operand type is not necessary to use two bitfields to generate the
index.

Gabe Black 64fe7af51a SPARC: Set up a lookup table for integer register flattening. 
Using a look up table changed the run time of the SPARC_FS solaris boot
regression from:

real    14m45.951s
user    13m57.528s
sys     0m3.452s

to:

real    12m19.777s
user    12m2.685s
sys     0m2.420s
