Chris Lattner	84cb260633	This is a carefully contrived testcase where the X86 ISel is emitting all loads ... before other ops, causing it to spill like mad. This occurs in 164.gzip:flush_block. llvm-svn: 19648	2005-01-17 23:16:01 +00:00
Chris Lattner	0c47dfe0ce	The pattern isel is aggressively codegen'ing all of the loads in these ... functions together at the start of the basic block, causing massive spillage. The old isel codegened the loads wherever they happened to land, so it generated good code for the first case, but bad code for the second. We really want the pattern isel to generate (the same) good code for both. llvm-svn: 19448	2005-01-11 03:05:03 +00:00
