Chandler Carruth	5da53436d5	Convert the uses of '\|&' to use '2>&1 \|' instead, which works on old versions of Bash. In addition, I can back out the change to the lit built-in shell test runner to support this. This should fix the majority of fallout on Darwin, but I suspect there will be a few straggling issues. llvm-svn: 159544	2012-07-02 18:37:59 +00:00
Jakob Stoklund Olesen	fb03a92c33	Be less aggressive about hinting in RAFast. In particular, don't spill dirty registers only to satisfy a hint. It is not worth it. The attached test case provides an example where the fast allocator would spill a register when other registers are available. llvm-svn: 132900	2011-06-13 03:26:46 +00:00

Be less aggressive about hinting in RAFast.

In particular, don't spill dirty registers only to satisfy a hint. It is
not worth it.

The attached test case provides an example where the fast allocator
would spill a register when other registers are available.
