similar to: [LLVMdev] internal compiler error when compiling llvm-gcc-4.2-2.9

I checked llvm-gcc 4.0 out from svn yesterday and am compiling it on 3 different machines. I was able to compile it on 2 of the machines, but the compilation failed on the third machine with the errors below. The machine that the compilation failed on is running Fedora Core 4. The processor is a AMD Athlon(tm) 64 Processor 3700+. The version of gcc I have on the machine is 4.0.2. I tried

Chris, I'm a little confused. I am experiencing a crash when compiling the llvm-gcc frontend. According to the bugpoint documentation, bugpoint is used to debug "optimizer crashes, miscompilations by optimizers, or bad native code generation," which seems like it implies that the frontend compiles. Also, the http://llvm.org/docs/HowToSubmitABug.html documentation seems to

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

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 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*

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, > >

Do you reserve some resource without verification? Note that reserveResources() should be

Hi, I'm trying to get the DFAPacketizer to work for my target but with any instruction I get the 'Assertion `CachedTable.count(StateTrans) != 0' failed' error and it crashes out before packeting a single instruction. I have a *GenDFAPacketizer.inc file and my packetizer pass checks that the table is not empty before proceeding. I also have a schedule file with my functional

Hi, When using llvm-ld to link .bc files(compiled with llvm-gcc with option --emit-llvm), I went into error like: file not recognized: File format not recognized. I was confused because llvm-ld is the LLVM linker to link llvm bitcode files together, then why this error occurred? I am using llvm 2.9 and the corresponding binary version of llvm-gcc. It will be appreciated if anyone of you can

Hi Ivan, The assertion was happening because I wasn't checking after the first attempt failed. The first packet was failing and so it was ended, and then the packetizer attempted to add it to the next packet without checking for available resources. However this highlights probably the real problem - my packetizer is unable to find resources for the first instruction, or any of my

I have a loop fully unrolled and got the following store instruction. store i32 %add.3, i32* getelementptr inbounds ([20 x [20 x i32]]* @c, i32 0, i32 0, i32 0), align 4 I want to know exactly which element of the array that is going to be stored, which help me to transform the high level language to hardware.

Hi Eric,  I was considering machine instructions to get scope information. And variable declaration does not correspond to machine instruction, hence the problem i.e. no scope associated with it. If 'i' is initialized in the 'if-scope' then we get 'variable i' mapped to correct scope as corresponding machine instruction is generated for this. This is not a problem as we

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

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
