Jakob Stoklund Olesen	2edaa2fb24	Move some of the InlineSpiller rematerialization code into LiveRangeEdit. ... llvm-svn: 116951	2010-10-20 22:00:51 +00:00
Jakob Stoklund Olesen	0f3e98ce2e	Move stack slot assignments into LiveRangeEdit. ... All registers created during splitting or spilling are assigned to the same stack slot as the parent register. When splitting or rematting, we may not spill at all. In that case the stack slot is still assigned, but it will be dead. llvm-svn: 116546	2010-10-15 00:16:55 +00:00
Jakob Stoklund Olesen	72911e49fa	Create a new LiveRangeEdit class to keep track of the new registers created when ... splitting or spillling, and to help with rematerialization. Use LiveRangeEdit in InlineSpiller and SplitKit. This will eventually make it possible to share remat code between InlineSpiller and SplitKit. llvm-svn: 116543	2010-10-14 23:49:52 +00:00
