2006-05-14This is a proper fix for the compiler warning. A termination condition isChris Lattner
not needed, as it can never be reached: an edge must exist. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28282 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-13Implement simple promotion for cast elimination in instcombine. This isChris Lattner
currently very limited, but can be extended in the future. For example, we now compile: uint %test30(uint %c1) { %c2 = cast uint %c1 to ubyte %c3 = xor ubyte %c2, 1 %c4 = cast ubyte %c3 to uint ret uint %c4 } to: _xor: movzbl 4(%esp), %eax xorl $1, %eax ret instead of: _xor: movb $1, %al xorb 4(%esp), %al movzbl %al, %eax ret More impressively, we now compile: struct B { unsigned bit : 1; }; void xor(struct B *b) { b->bit = b->bit ^ 1; } To (X86/PPC): _xor: movl 4(%esp), %eax xorl $-2147483648, (%eax) ret _xor: lwz r2, 0(r3) xoris r2, r2, 32768 stw r2, 0(r3) blr instead of (X86/PPC): _xor: movl 4(%esp), %eax movl (%eax), %ecx movl %ecx, %edx shrl $31, %edx # TRUNCATE movb %dl, %dl xorb $1, %dl movzbl %dl, %edx andl $2147483647, %ecx shll $31, %edx orl %ecx, %edx movl %edx, (%eax) ret _xor: lwz r2, 0(r3) srwi r4, r2, 31 xori r4, r4, 1 rlwimi r2, r4, 31, 0, 0 stw r2, 0(r3) blr This implements InstCombine/cast.ll:test30. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28273 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-12Don't use old-style casts. This prevents compiler warnings when CommandLine.hReid Spencer
is used in projects that have stricter warning control than LLVM. This also helps us find casts more easily if we ever need to. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28263 91177308-0d34-0410-b5e6-96231b3b80d8
