Hi, in lib/Analysis/RegionPass.cpp there are 3 occurrences of: CurrentRegion->getNameStr() These are slowing down compile times with polly. I would suggest to either remove these calls, or only turn on when the programmer asks for -debug. The reason for the slow pretty printing of types is the same as previously discussed in: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-July/063755...

Hi, Suppose I have llvm Instruction as : %9 = load i32* %b, align 4 and I want to extract the name of temporary value used here ie 9. Can any body tell that how can I do that? thanks and regards, Ambika

Thanks, Jay.

Note that not all instructions have names (i.e., getNameStr() might give you an empty string). I think the LLVM disassembler prints a number when the instruction has no name. There's a pass which, I think, gives names to all values, but I don't recall the pass's name. -...

Hi Duncan, Thanks for pointing out my mistake. I will reword my questions. //C code int var1; //global int a, b; foo(a, b); bar(c); generates following //LLVM IR %1 = load a; %2 = load b; call foo(%1, %2) call bar(@var1) CallInst.getOperand(1).getNameStr() on foo, returns null, but on bar returns var1. Similarly, for call void @p_ptr(i64 ptrtoint (%struct.my_struct* @abc to i64)) nounwind, !dbg !31 CallInst.getOperand(1).getNameStr(), return abc and type returns i64, How do I figure the operand is a const expression and a cast operator was used...

...own entry points in an opt pass, but it's currently failing to get the file name and path back, though it is still correctly getting line numbers. If you happen to have a code fragment that is known to work, it would be much appreciated. What it used to work was calling getFileName()->getNameStr() on the DbgStopPointInst, which returned a std::string, but in LLVM 2.5 the code compiles, but that string is empty. Any clues? [s]

Hi, I have Value V of Type i32*. How can I convert/set it's Type to i32? Or How can I create another Value of Type i32 and with same name as V. I have tried Value *NewV = new Value(Type,scid); NewV->setName(V->getNameStr()); It causes stack dump. I am not sure as second argument in the Value constructor as scid (SubClassID). So I have mentioned 0. Any Idea how to do this? Regards, Chayan

Hi all, There are many assertions sprinkled throughout the llvm codebase, which is a GoodThing. Most of the assertions even have informative messages, which is a BetterThing. However, assertion messages are static strings, and don't include any information about the particular object/value which caused the assertion. In a 'data oriented' system like llvm, this makes it really
