Chris Lattner c686a9ab37 Fix a minor code-quality issue. When passing 8 and 16-bit integer constants ... to function calls, we would emit dead code, like this: int Y(int, short, double); int X() { Y(4, 123, 4); } --- Old X: sub %ESP, 20 mov %EAX, 4 mov DWORD PTR [%ESP], %EAX *** mov %AX, 123 mov %AX, 123 movsx %EAX, %AX mov DWORD PTR [%ESP + 4], %EAX fld QWORD PTR [.CPIX_0] fstp QWORD PTR [%ESP + 8] call Y mov %EAX, 0 # IMPLICIT_USE %EAX %ESP add %ESP, 20 ret Now we emit: X: sub %ESP, 20 mov %EAX, 4 mov DWORD PTR [%ESP], %EAX mov %AX, 123 movsx %EAX, %AX mov DWORD PTR [%ESP + 4], %EAX fld QWORD PTR [.CPIX_0] fstp QWORD PTR [%ESP + 8] call Y mov %EAX, 0 # IMPLICIT_USE %EAX %ESP add %ESP, 20 ret Next up, eliminate the mov AX and movsx entirely! llvm-svn: 12026		2004-03-01 02:34:08 +00:00
