Hi all, Right now the Mangler::getValueName() method will produce something like "__unnamed_1_37" for a global value that doesn't have a name. This is wrong for Objective-C where CFStrings will get these labels, thus preventing the linker from coalescing them. [/tmp]> nm -s __DATA __cfstring -m foo.o 00000000000244d0...

Can symbols with external linkage but no name be converted to have internal linkage? Would that solve the problem?

The second one won't work in more complicated situations. Why do you want the names anyway? Ciao, Duncan.

Hi Duncan, >>are you trying to get the name "@_ZTIi" or "@__cxa_throw"? yes! i want get the name @_ZTi or @__cxa_throw, the latter @__cxa_throw i can get it throw value->getName(), but the @_ZTi it did n't has name! zhangzw thanks 2009/3/26 Duncan Sands <baldrick at free.fr>: > Hi zhangzw, > >> invoke void @__cxa_throw(i8* %7, i8*

...at example we use virtual register 0) and my pass cannot do it. I'm using the following piece of code in my pass: for (inst_iterator I = inst_begin(F), E = inst_end(F); I != E; ++I){ if((*I).getOpcode() == Instruction::Load){ errs() << cast<LoadInst>(*I).getValueName() << "\n"; } } The method getValueName() gives nothing as well as getName() or getValueID(). Because of this I'm not able to detect that b is dependent on a. However if I have something like this: store i32 0, i32* %a, align 4 %tmp = load i32* %a, align 4...

Hi, I’m writing a loop-free LLVM pass, my thought is to track if the value inside the loop is changed, so I look up the Instruction StoreInst first and try to get its value in a set. I checked getValueOperand(), getValueName() in the API document but unfortunately they failed the compilation. if (isa<StoreInst>(I)){ Value* v = I.getOperand(0); Instruction* op1 = dyn_cast<Instruction>(v); errs()<< v << "\t" << v1-getName()<<"\t"<<op<<\n&quo...

I have tried the following :- if (!M.empty()) for (Module::iterator I = M.begin(), E = M.end(); I != E; ++I) if ( !I->getIntrinsicID() && I->getEntryBlock().empty()) O << "EXTERN " << Mang->getValueName(I) << " : NEAR" << "\n"; Based upon :- virtual bool Function::isExternal() const { return BasicBlocks.empty(); } But it does not work either. Which means there must be a BasicBlock occuring on undefined/external functions. Anyway no hurry I am off to do othe...

Hi All,   Can we extract name of variable name from "MDNode" ?   1. Neither temp_MDNode->getName() nor temp_MDNode->getValueName() give me "global_int" which is name of a variable.   2. I tried below ways as well. DIVariable DV(mdnode1); Value *v = mdnode1->getOperand(0);//gives add 0x69   3. I have written below code to reach till variable name.        LLVMIname is                 const CallInst *CI = dyn_cas...

The LLVM asm parser doesn't support multiple alternative constraints; you need to have Clang pick one tuple in the front end. See ChooseConstraintTuple in llvm-gcc for prior art.

I'm trying to fix the handling of multiple alternate constraints in Clang (see http://gcc.gnu.org/onlinedocs/gcc/Multi_002dAlternative.html#Multi_002dAlternative ). How should the constraints be represented in the .ll file? Clang currently will assert because the code generator sees a constraints string with the wrong number of comma-separated items. Basically, after some editing, it just

For some reason there is a BasicBlock present on undefined functions ! I am compiling the examples from llvm/test/feature, about 28 out of 34 assemble fine. Just cannot seem to get
