Hi, I have this piece of code: tm = local ? localtime(&curr) : gmtime(&curr); if (!tm) return NULL; which translates into something like: ---------------------------------------------- entry: %iftmp.0 = alloca %struct.tm*, align 8 %tm = alloca %struct.tm*, align 8 ... // Declares iftmp.0 as iftmp.0 call void @llvm.dbg.declare( { }* %iftmp.0, { }* bitcast (%llvm.dbg.variable.type* @llvm.dbg.variable792014 to { }*) ) // Declares tm as tm call void @llvm.dbg.declare( {...

Hi, I have been trying to move some instructions between basic blocks , After looking at the API , I found llvm::Instruction::clone() but there is no result value for this. For example- source Basic block : continuation: ; preds = %else, %then %iftmp = phi i32 [ 5, %then ], [ 9, %else ] store i32 %iftmp, i32* %datasize ; 3 instructions below being copied store i8000000 0, i8000000* %res %res4 = load i8000000, i8000000* %res ret i8000000 %res4 After copying the 3 instructions above to destination basic block. destination basic block...

Hi, all I'd like to write a code that can build different codes based on LLVM version. Like code snippets in the below. #ifdef __LLVM_29__ PHINode *PN = Builder.CreatePHI (Type::getDoubleTy(getGlobalContext()), 2, "iftmp"); #elif __LLVM_28__ PHINode *PN = Builder.CreatePHI (Type::getDoubleTy(getGlobalContext()), "iftmp"); #else assert ("wrong version"); #endif I've been trying to find something like these (__LLVM_29__, __LLVM_28__), but I couldn't find them yet. Thanks for...

...e Def/Use analysis, and I'm hung up on one tricky spot. The BB in question is attached. Ignore the red. The issue is that '%13 = load...' instruction does not show up as a Use for the '%scevgep25' definition, and I feel like it should. Instead, it shows up as a Use for '%iftmp.55.0 = select...', though Operand(0) for this '%13 = load' instruction [listed as a Use for '%iftmp.55.0 = select...'] is reported as the %scevgep25 instruction, which is correct. Sorry if that was a bit convoluted. Essentially, it seems that 'getelementptr' instructio...

...est/Transforms/InstCombine/2006-05-06-Infloop.ll. The original code truncates two i32 values to i8 and eventually ORs them together.

Hi all, I'm trying to implement a floating-point 'min' and 'max' operation using select. For 'min' I get the expected x86 assembly minss instruction, but for 'max' I get a branch instead of maxss. The corresponding C syntax code looks like this: float z = (x > y) ? x : y; Any clues? Could someone maybe explain to me the basics of

instcombine can handle certain orders of "icmp"s that are "or"ed together: x != 5 OR x > 10 OR x == 8 becomes.. x != 5 OR x == 8 becomes.. x != 5 However, a different ordering prevents the simplification: x == 8 OR x > 10 OR x != 5 becomes.. %or.eq8.gt10 OR x != 5 and that can't be simplified because we now have an "or" OR "icmp". What would I

Dear All, I have, in an LLVM bitcode program, the following phi node: %iftmp.225.0 = phi i8* [ getelementptr ([10 x i8]* @.str12597431, i32 0, i32 0), %bb114 ], [ getelementptr ([10 x i8]* @.str1258, i32 0, i32 0), %bb111 ], [ getelementptr ([10 x i8]* @.str1258, i32 0, i32 0), %bb111 ] This phi instruction has two arguments for the same incoming basic block. The only rea...
