2004-04-07This is a start on handling setcc instructions. As the comment notes, weChris Lattner
have no good way of handling this until the code generator is improved. We should probably just emit V9 instructions in the meantime. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12745 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-06Improve codegen of long == and != comparisons against constants. Before,Chris Lattner
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

2004-04-06Handle various other important cases of multiplying a long constant ↵Chris Lattner
immediate. For example, multiplying X*(1 + (1LL << 32)) now produces: test: mov %ECX, DWORD PTR [%ESP + 4] mov %EDX, DWORD PTR [%ESP + 8] mov %EAX, %ECX add %EDX, %ECX ret [[[Note to Alkis: why isn't linear scan generating this code?? This might be a problem with your intervals being too conservative: test: mov %EAX, DWORD PTR [%ESP + 4] mov %EDX, DWORD PTR [%ESP + 8] add %EDX, %EAX ret end note]]] Whereas GCC produces this: T: sub %esp, 12 mov %edx, DWORD PTR [%esp+16] mov DWORD PTR [%esp+8], %edi mov %ecx, DWORD PTR [%esp+20] xor %edi, %edi mov DWORD PTR [%esp], %ebx mov %ebx, %edi mov %eax, %edx mov DWORD PTR [%esp+4], %esi add %ebx, %edx mov %edi, DWORD PTR [%esp+8] lea %edx, [%ecx+%ebx] mov %esi, DWORD PTR [%esp+4] mov %ebx, DWORD PTR [%esp] add %esp, 12 ret I'm not sure example what GCC is smoking here, but it looks like it has just confused itself with a bunch of stack slots or something. The intel compiler is better, but still not good: T: movl 4(%esp), %edx #2.11 movl 8(%esp), %eax #2.11 lea (%eax,%edx), %ecx #3.12 movl $1, %eax #3.12 mull %edx #3.12 addl %ecx, %edx #3.12 ret #3.12 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12693 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-06Efficiently handle a long multiplication by a constant. For this testcase:Chris Lattner
long %test(long %X) { %Y = mul long %X, 123 ret long %Y } we used to generate: test: sub %ESP, 12 mov DWORD PTR [%ESP + 8], %ESI mov DWORD PTR [%ESP + 4], %EDI mov DWORD PTR [%ESP], %EBX mov %ECX, DWORD PTR [%ESP + 16] mov %ESI, DWORD PTR [%ESP + 20] mov %EDI, 123 mov %EBX, 0 mov %EAX, %ECX mul %EDI imul %ESI, %EDI add %ESI, %EDX imul %ECX, %EBX add %ESI, %ECX mov %EDX, %ESI mov %EBX, DWORD PTR [%ESP] mov %EDI, DWORD PTR [%ESP + 4] mov %ESI, DWORD PTR [%ESP + 8] add %ESP, 12 ret Now we emit: test: mov %EAX, DWORD PTR [%ESP + 4] mov %ECX, DWORD PTR [%ESP + 8] mov %EDX, 123 mul %EDX imul %ECX, %ECX, 123 add %ECX, %EDX mov %EDX, %ECX ret Which, incidently, is substantially nicer than what GCC manages: T: sub %esp, 8 mov %eax, 123 mov DWORD PTR [%esp], %ebx mov %ebx, DWORD PTR [%esp+16] mov DWORD PTR [%esp+4], %esi mov %esi, DWORD PTR [%esp+12] imul %ecx, %ebx, 123 mov %ebx, DWORD PTR [%esp] mul %esi mov %esi, DWORD PTR [%esp+4] add %esp, 8 lea %edx, [%ecx+%edx] ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12692 91177308-0d34-0410-b5e6-96231b3b80d8
