2010-07-10The accumulator tail recursion transform claims to work for any associativeDuncan Sands
operation, but the way it's implemented requires the operation to also be commutative. So add a check for commutativity (and tweak the corresponding comments). This makes no difference in practice since every associative LLVM instruction is also commutative! Here's an example to show the need for commutativity: the accum_recursion.ll testcase calculates the factorial function. Before the transformation the result of a call is ((((1*1)*2)*3)...)*x while afterwards it is (((1*x)*(x-1))...*2)*1 which clearly requires both associativity and commutativity of * to be equal to the original. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108056 91177308-0d34-0410-b5e6-96231b3b80d8

(X >s -1) ? C1 : C2 and (X <s 0) ? C2 : C1 into ((X >>s 31) & (C2 - C1)) + C1, avoiding the conditional. This optimization could be extended to take non-const C1 and C2 but we better stay conservative to avoid code size bloat for now. for int sel(int n) { return n >= 0 ? 60 : 100; } we now generate sarl $31, %edi andl $40, %edi leal 60(%rdi), %eax instead of testl %edi, %edi movl $60, %ecx movl $100, %eax cmovnsl %ecx, %eax git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107866 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-07Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts"Duncan Sands
builds to "Release". The default build is unchanged (optimization on, assertions on), however it is now called Release+Asserts. The intent is that future LLVM releases released via llvm.org will be Release builds in the new sense, i.e. will have assertions disabled (currently they have assertions enabled, for a more than 20% slowdown). This will bring them in line with MacOS releases, which ship with assertions disabled. It also means that "Release" now means the same things in make and cmake builds: cmake already disables assertions for "Release" builds AFAICS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107758 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-01Implement the "linker_private_weak" linkage type. This will be used forBill Wendling
Objective-C metadata types which should be marked as "weak", but which the linker will remove upon final linkage. However, this linkage isn't specific to Objective-C. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". Currently only supported on Darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107433 91177308-0d34-0410-b5e6-96231b3b80d8
