Chris Lattner e80e637793 Improve codegen of long == and != comparisons against constants. Before, ... comparing a long against zero got us this: sub %ESP, 8 mov DWORD PTR [%ESP + 4], %ESI mov DWORD PTR [%ESP], %EDI mov %EAX, DWORD PTR [%ESP + 12] mov %EDX, DWORD PTR [%ESP + 16] mov %ECX, 0 mov %ESI, 0 mov %EDI, %EAX xor %EDI, %ECX mov %ECX, %EDX xor %ECX, %ESI or %EDI, %ECX sete %CL test %CL, %CL je .LBB2 # PC rel: F Now it gets us this: mov %EAX, DWORD PTR [%ESP + 4] mov %EDX, DWORD PTR [%ESP + 8] mov %ECX, %EAX or %ECX, %EDX sete %CL test %CL, %CL je .LBB2 # PC rel: F git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12696 91177308-0d34-0410-b5e6-96231b3b80d8		2004-04-06 16:02:27 +00:00
