...bb2 also has several successors(before bb_join), which are not pruned together with bb2. Is there any existing API to remove them as well? Also, in Step 4, could I just call bb2->eraseFromParent() without dropping any references? I am a bit confused with the function dropAllReferences.

Thanks for your help, Wei-Ren and Anton. However since I am doing some experiments with klee( http://klee.llvm.org/GetStarted.html) and llvm-gcc seems to have better compatibility with it. So I still hope that I can use llvm-gcc:-) Hongxu Chen On Sat, Mar 16, 2013 at 3:35 PM, 陳韋任 (Wei-Ren Chen) [via LLVM] < ml-node+s1065342n56013h94 at n5.nabble.com> wrote: > Hi Chen, > > llvm-gcc is dead.

That looks like the issue Hongxu mentioned: you're always creating a new Function (at which point LLVM renames it if one already exists) when you should really be calling GetOrInsertFunction to lookup an existing "printf" if it's available. Cheers. Tim.

Hi everyone, I have some trouble in instrumenting load instructions. I want to instrument load instructions as follow: Firstly, I judge whether the loaded pointer(*any type is possible*) is NULL. If so, I want to explicitly allocate the corresponding address space of its type to the pointer. For example, in source code level I want to translate the next statement *p = 1; into the next

Thanks,Cheers! I found the problem is that the "Function *call_print" using the same name as the “class call_print”, which made the compiler wrongly resolved the call_print type! But I got another problems. I successfully compile the pass and I can insert the call printf (C Lib function) instructions in the LLVM IR(eg: call.bc). If the call.bc didn't contain call printf

Hi, this question might be a bit silly: apart from the language reference(http://llvm.org/docs/LangRef.html#switch-instruction) page, are there additional rules for a regular llvm frontend to generate llvm IRs? There are a few cases that I got from clang/llvm-gcc/dragonegg when compiling *C* source code into llvm IR: 1. It seems that there is ONLY ONE ReturnInst(and NO InvokeInst) for such llvm

...better way. Also AFAIK, using cmake is much easier for this case since it only needs to use this configuration in mypass/Makefile: add_llvm_loadable_module( mypass mypass.cpp sub/basic.cpp ) But for some reasons I have to use GNU make to do this. Is there a good way? -- Regards, Hongxu Chen

Hi Chen, llvm-gcc is dead. Try dragonegg [] or clang [2].

hi, with LLVM 3.1, i am trying to compile toy.cpp from http://llvm.org/docs/tutorial/LangImpl7.html#code. i got the following error: $ clang++ -g toy.cpp `llvm-config --cppflags --ldflags --libs core jit native` -O3 -o toy toy.cpp:4:10: fatal error: 'llvm/IRBuilder.h' file not found #include "llvm/IRBuilder.h" i fixed this by modifying the broken line to: #include

Hi all, I need to know the line number range of a function. The start of the function line number can be found by the definition point, which is stored at the subprogram metadata: DISubprogram::getLineNumber(). However, there is no API (or the metadata in the first place) to know the end of the function. I have to visit all the instructions of the function and maintain the *max*line number of

Hi Jin, It's difficult to say just from looking at a pass, but one thing looked odd: > CallInst *call_print = CallInst::Create(call_print,paramArrayRef,"",ins_temp); This looks very dodgy. The "call_print" being used as an argument is the (uninitialised) one that's just been declared. This could be the source of the assertion failure (though a segfault is just as

Hello, everyone! I want to write a pass which can insert a call "printf" instructions before every instruction in the LLVM IR. here is what I wrote: namespace { class call_print : public FunctionPass{ private: DenseMap<const Value*, int> inst_map; public: static char ID; call_print() : FunctionPass(ID){} //define a extern function "printf" static llvm::Function*
