David Greene 7cfd336af6 Add support for spreading register allocation. ... Add a -linearscan-skip-count argument (default to 0) that tells the allocator to remember the last N registers it allocated and skip them when looking for a register candidate. This tends to spread out register usage and free up post-allocation scheduling at the cost of slightly more register pressure. The primary benefit is the ability to backschedule reloads. This is turned off by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89356 91177308-0d34-0410-b5e6-96231b3b80d8		2009-11-19 15:55:49 +00:00
