...analysis pass. My pass need to use some result from some other tools. I can hard code a file name into my pass, and let my pass read input there, but what if I do not want the file name to be hard coded? Is it possible to do that? If yes, where can I find some documentation about it? Thanks, Guoliang

I did not see the same thing at the documentation for release 2.7. Thanks, Guoliang -------------- next part -------------- An HTML attachment was scrubbed...

You can use llvm::sys::Path::GetTemporaryDirectory() and put the inputs and outputs there.

...ion fails } return I->second-1; } The output show me that the V that it complains is not the ValueMap, but the content of *V is in the ValueMap. This happened when I applied my pass to some modules from .cpp, and my pass worked on some modules from .c files. Any hint on this? Thanks, Guoliang

...na use the gold plugin, but I got the following: libLLVMgold.so: could not load plugin library Do you know why this is happening? Also I noticed the name of the library is changed to LLVMgold.so, and I just renamed it to libLLVMgold.so when I copied it. Is this the right thing to do? Thanks, Guoliang

...bably because of some optimization during the final link stage? If this is the case, can you point me what those optimizations are, so that I could also apply them while compiling per file bytecode to native code. Or am I using the wrong way to compile per file bytecode to native code? Thanks, Guoliang

...d_hook() and compiled one autotooled program (ftp://ftp.gnu.org/gnu/diction/diction-1.11.tar.gz) as described in the gold plugin document, however, I still did not see the output.bc. Can anyone has succeeded in doing this share with me how you archive this or what I may miss? Thanks very much, Guoliang

Hi there, I checked out the poolalloc project from svn repository. I got the error ‘addPeakMemoryMeasurement’ is not a member of ‘llvm::Timer’ while compiling. Does poolalloc only compile under LLVM 2.7 or earlier, but not the LLVM under development? Thanks, Guoliang

Hi, In the objdump for binary, there is always an address associated with an instruction. In the bitcode file, is there a way to address an instruction? It does not have to be a single ID like objdump. Thanks, Guoliang

Hi Guoliang, > I added a function to a module, but failed to write the bitcode to file > because it hit the: > assert(I != ValueMap.end()&& "Value not in slotcalculator!") does the module pass the verifier after you add the function to it? Ciao, Duncan.

Some things to check: Run llvm-gcc a.c -emit-llvm -use-gold-plugin -Wl,debug This will print the link command line. What is it? Do you get the same error messages if you run just that? Are gold and the plugin linked with the same libstdc++?

...ure: error: C compiler cannot create executables ..." when I following those instructions. Any experience on compiling autotooled projects using LLVM is welcome. Some online resource on this topic will be great. I am new to this list, and I guess this topic may be discussed before. Thanks, Guoliang
