similar to: [LLVMdev] How to explain this weird phenomenon????????

I figured that my opt command is wrong! How to specify the output file anyway?? if I want hello.bc to be input file and newhello.bc to be output file, is the opt command go like this? opt -load ../../../Debug+Asserts/lib/Hello.so -hello <hello.bc> -o newhello.bc ?? -- 祝好！ 甄凯

Hi, I don't think the code you pasted can be the correct code, where does FibF come from? Anyway, the problem is that you're calling the FibF from Module A, however you defined it for Module B. You need to insert the FibF function into the Module that you're running. To do this override "virtual bool doInitialization(Module &M);" and insert FibF into M. Joey 2012/4/9

Hi all， Im trying to instrument this hello function right before the instruction that call the "puts" function(the source code is as follow). Now I can compile the pass without errors, but when run the pass with opt tool, it broke down. The diagnose is something like Referencing function in another module! %CallCheck = call i32 @fib() Broken module found, compilation aborted! Does

I did it !!!!

Thank you very much! To make it simpler, I may as well just implement the self-written "check function" in C language instead of wrapping it in LLVM module. According to the hint you give me, all I need to do is as follow(?) 1. Implement the "Check function" in the check.c file; 2. Add the check function into the module(the Hello1.bc file which I will run the functionPass on)

That sounds like a good general plan, yes!

Your files do not appear to implement the check() function.

Hi, I got upset.. What does “Broken module found, compilation aborted!” mean really?? what‘s “broken module“?? -- 祝好！ 甄凯 ------------------------------------------------------------------------------------------------------ 2012-04-09 ------------------------------------------------------------------------------------------------------ Name: 甄凯(ZhenKai)

Hi, my friends I finally insert the callInst into the hello.bc file.Then I compile the hello.bc to hello.o file and the check.c to check.o file. And I think by link those to .o file togetherI can get the executable ELF file(clang hello.o check.o -o finalfile). But when I link the two objective file, it said "hello.o: In function `main': hello.bc:(.text+0x69): undefined reference to

Hi all, I wrote a function pass. In the pass, it ran through all the instruction that call to functions. When arriving at the exact function that I m interested in, it would insert a self-made function. Now I've finished the pass, the compilation is successful. The pass can find the function I like and can insert the CallInst to call my check function. BUT, when running the

Yeah, but I tried that command and error message was generated: hellomodule.c:1:10: fatal error: 'linux/init.h' file not found #include <linux/init.h> ^ 1 error generated. how to solve this problem?? Thanks! -- 祝好！ 甄凯 ------------------------------------------------------------------------------------------------------ 2012-04-12

Ok, that makes sense! That is to say, I don't need a makefile (in which to specify the path to kernel) to compile it. Just a clang command with some option will do it, right? -- 祝好！ 甄凯 ------------------------------------------------------------------------------------------------------ 2012-04-12

It's actually is .c file. I just want firstly to compile helloworldmodule.c into helloworldmodule.bc. Then I run a LLVM pass on it to do some optimization, and then I compile the modified .bc file into .ko file. So, could you tell me how to compile helloworldmodule.c into helloworldmodule.bc? I think it's not the same command "clang -O3 -emit-llvm hello.c -c -o hello.bc".

Wow that's to much output information. Maybe I can put it in this way. Could you tell me the clang option that can include the linux kernel headers??? Something like "clang -O3 -isystem /lib/modules/`uname -r`/build/include -emit-llvm hellomodule.c -c -o hellomodule.bc" Thank you! -- 祝好！ 甄凯

Hi, Nick I think that's the question. I just don't know what's the command line that can tell clang to find the linux head file like a makefile will do. Please help me! -- 祝好！ 甄凯 ------------------------------------------------------------------------------------------------------ 2012-04-12

Well, you do have to include all the -I and -D options so that clang can find the Linux kernel header

Hi, my friends I know there is a difference between compiling a linux module and a simple helloworld programme. If I compile a helloworld.c file, the command is "clang -O3 -emit-llvm hello.c -c -o hello.bc" But what the command should be if I want to compile a linux module into a .bc file? (I know it may be an easy question to you guys, but I really don't know where to find the

In the linux kernel, "make V=1" will compile verbosely, printing out each command it runs. Each .o file produced will have its own command-line (many of them will be

Hi all, I want to run a function pass on a certain .bc file. In the process, the pass will insert a check function into the .bc file. I know the .bc file is regarded as a module in LLVM. So, there are two basic steps needed to be done, 1, Use the "getOrInsertFunction"API to add a declaration of the extern "check function". 2, Use the "insertBefore"API to insert the
