similar to: [LLVMdev] In llvm, how can I delete a whole branch elegantly?

Hi everyone, (Sorry if I'm asking at the wrong mail listing, but compiler-rt page tells I'd better write on llvm-dev rather than cfe-dev/cfe-users.) I've just built LLVM/Clang+Compiler-rt (Compiler-rt is put inside llvm/projects folder) and tried the -fsanitize option. But strangely the link failed since it cannot find *libclang_rt.san-x86_64.a*. The error message is as

While compiling openssl with option `no-des', it caused the openssh build failure ... cipher.c:85:41: error: 'EVP_des_ede3_cbc' undeclared here (not in a function); ...

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, > >

Hi everyone, Recently I tried to compile llvm-gcc-4.2-2.9 on a 64bit ubuntu12.04 machine. And I was using the settings below, export C_INCLUDE_PATH=/usr/include/x86_64-linux-gnu export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu ../llvm-gcc-4.2-2.9.source/configure --enable-optimized --program-prefix=llvm- --enable-checking --enable-llvm=${HOME}/moonbox/llvm-obj/Debug+Asserts

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

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

Hi, Whenever Asterisk restarts, some values such as DEVSTATE ones, should be reset. How would you proceed to have those settings done anytime Asterisk restarts ? I was thinking of using #exec statement in appropriate .conf file. Ant better idea ? Regards -------------- next part -------------- An HTML attachment was scrubbed... URL:

I've found the need to compute a version of order(x,y) where I want the sort order for *increasing* x and *decresing* y ... something we could imagine could be provided in the future as order(x,y, decreasing = c(FALSE, TRUE)) i.e., using a 'vectorized' decreasing argument. {No, I'm not volunteering right now!} I've found the following R-level solution and like to quiz

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*
