Devang Patel	b0faf89133	Preserve paramater attributes. llvm-svn: 47847	2008-03-03 18:36:03 +00:00

Devang Patel	4eedfd2421	Add pass to promote sret. This pass transforms %struct._Point = type { i32, i32, i32, i32, i32, i32 } define internal void @foo(%struct._Point* sret %agg.result) into %struct._Point = type { i32, i32, i32, i32, i32, i32 } define internal %struct._Point @foo() This pass updates foo() clients appropriately to use getresult instruction to extract return values. This pass is not yet ready for prime time. llvm-svn: 47776	2008-02-29 23:34:08 +00:00
