Jakob Stoklund Olesen 00005782fa Add support for multi-way live range splitting. ... When splitting global live ranges, it is now possible to split for multiple destination intervals at once. Previously, we only had the main and stack intervals. Each edge bundle is assigned to a split candidate, and splitAroundRegion will insert copies between the candidate intervals and the stack interval as needed. The multi-way splitting is used to split around compact regions when enabled with -compact-regions. The best candidate register still gets all the bundles it wants, but everything outside the main interval is first split around compact regions before we create single-block intervals. Compact region splitting still causes some regressions, so it is not enabled by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136186 91177308-0d34-0410-b5e6-96231b3b80d8		2011-07-26 23:41:46 +00:00
