Jakob Stoklund Olesen c1a6340d54 Also attempt trivial coalescing for live intervals that end in a copy. ... The coalescer is supposed to clean these up, but when setting up parameters for a function call, there may be copies to physregs. If the defining instruction has been LICM'ed far away, the coalescer won't touch it. The register allocation hint does not always work - when the register allocator is backtracking, it clears the hints. This patch is more conservative than r90502, and does not break 483.xalancbmk/i686. It still breaks the PowerPC bootstrap, so it is disabled by default, and can be enabled with the -trivial-coalesce-ends option. llvm-svn: 91049		2009-12-10 17:48:32 +00:00
