Chris Lattner e5eb6f829c Add some simplifications for MULH[SU]. This allows us to compile this: ... long %bar(long %X) { %Y = mul long %X, 4294967297 ret long %Y } to this: l1_bar: mov %EAX, DWORD PTR [%ESP + 4] mov %EDX, %EAX add %EDX, DWORD PTR [%ESP + 8] ret instead of: l1_bar: mov %ECX, DWORD PTR [%ESP + 4] mov %EDX, 1 mov %EAX, %ECX mul %EDX add %EDX, %ECX add %EDX, DWORD PTR [%ESP + 8] mov %EAX, %ECX ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22044 91177308-0d34-0410-b5e6-96231b3b80d8		2005-05-15 05:39:08 +00:00
