Chris Lattner 8e76764de8 add one more bitfield optimization, allowing clang to generate ... good code on PR4216: _test_bitfield: ## @test_bitfield orl $32962, %edi movl $4294941946, %eax andq %rdi, %rax ret instead of: _test_bitfield: movl $4294941696, %ecx movl %edi, %eax orl $194, %edi orl $32768, %eax andq $250, %rdi andq %rax, %rcx movq %rdi, %rax orq %rcx, %rax ret Evan is looking into the remaining andq+imm -> andl optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93147 91177308-0d34-0410-b5e6-96231b3b80d8		2010-01-11 06:55:24 +00:00
