Chris Lattner 05f18920e1 Teach inst combine to merge GEPs through PHIs. This is really ... important because it is sinking the loads using the GEPs, but not the GEPs themselves. This triggers 647 times on 403.gcc and makes the .s file much much nicer. For example before: je LBB1_87 ## bb78 LBB1_62: ## bb77 leal 84(%esi), %eax LBB1_63: ## bb79 movl (%eax), %eax ... LBB1_87: ## bb78 movl $0, 4(%esp) movl %esi, (%esp) call L_make_decl_rtl$stub jmp LBB1_62 ## bb77 after: jne LBB1_63 ## bb79 LBB1_62: ## bb78 movl $0, 4(%esp) movl %esi, (%esp) call L_make_decl_rtl$stub LBB1_63: ## bb79 movl 84(%esi), %eax The input code was (and the GEPs are merged and the PHI is now eliminated by instcombine): br i1 %tmp233, label %bb78, label %bb77 bb77: %tmp234 = getelementptr %struct.tree_node* %t_addr.3, i32 0, i32 0, i32 22 br label %bb79 bb78: call void @make_decl_rtl(%struct.tree_node* %t_addr.3, i8* null) nounwind %tmp235 = getelementptr %struct.tree_node* %t_addr.3, i32 0, i32 0, i32 22 br label %bb79 bb79: %iftmp.12.0.in = phi %struct.rtx_def** [ %tmp235, %bb78 ], [ %tmp234, %bb77 ] %iftmp.12.0 = load %struct.rtx_def** %iftmp.12.0.in git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60322 91177308-0d34-0410-b5e6-96231b3b80d8		2008-12-01 02:34:36 +00:00
