* Remove the local register allocator.Jakob Stoklund Olesen2010-06-151-1/+0
| | | | | | Please use the fast allocator instead. llvm-svn: 106051
* Enable a bunch more -regalloc=fast testsJakob Stoklund Olesen2010-05-121-0/+1

* Enable -split-phi-edges by default, except when -regalloc=local.Jakob Stoklund Olesen2009-11-171-0/+1
| | | | | | | The local register allocator doesn't like it when LiveVariables is run. We should also disable edge splitting under -O0, but that has to wait a bit. llvm-svn: 89125
* Revert 89021. It's miscompiling llvm-gcc driver driver at -O0.Evan Cheng2009-11-171-5/+1

* Eliminate more uses of llvm-as and llvm-dis.Dan Gohman2009-09-081-2/+2

* Second attempt:Bill Wendling2009-04-291-1/+1
| | | | | | | | | | | | Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'll change the JIT with a follow-up patch. llvm-svn: 70343

* Rewrite LiveVariable liveness computation. The new implementation is much ↵Evan Cheng2008-04-161-0/+48
simplified. It eliminated the nasty recursive routines and removed the partial def / use bookkeeping. There is also potential for performance improvement by replacing the conservative handling of partial physical register definitions. The code is currently disabled until live interval analysis is taught of the name scheme. This patch also fixed a couple of nasty corner cases. llvm-svn: 49784
