similar to: [LLVMdev] passing parameters for a analysis pass

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

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++? Cheers On Jun 5, 2010 11:50 PM, "Guoliang Jin" <jingl1345 at gmail.com> wrote: The errors are /usr/lib/libstdc++.so.6: version

If you think a commandline option is the way to go, LLVM makes it pretty easy to do so, see the documentation here: http://llvm.org/docs/CommandLine.html . Mostly you can just add an appropriate "cl::opt<string>" option (for your filename, for example) and you're on your way. ~Will On Wed, Jul 7, 2010 at 9:55 PM, Reid Kleckner <reid.kleckner at gmail.com> wrote: >

The errors are /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.9' not found /lib/libc.so.6: version `GLIBC_2.7' not found I can not use it in the command line...

Hi, I would like to get the whole program bitcode with debug information in it. I tried to use CFLAGS = "-O4 -g", but it ends with the following error: collect2: ld terminated with signal 6 [Aborted] Unknown constant! UNREACHABLE executed at /local.toadette/aliang/fixing/llvm-2.7/llvm-2.7/lib/Bitcode/Writer/BitcodeWriter.cpp:895! What is the right way to get a whole program bitcode

Hi there, I checked out the latest code from the repository, and wanna 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

Hi, I am using gold plugin with the option "-use-gold-plugin -Wl,-plugin-opt=also-emit-llvm" to compile apache. I objdumped the final executable httpd to httpd.S. I also compiled those per file bytecode into native code using the following: llc filename.o llvm-gcc -c filename.o.s -o filename.o.o Then I objdumped filename.o.o to filename.o.S and compared some functions between

Thanks Rafael. I compiled llvm-gcc by myself, and I can compile mysql now. Right now, when I run llvm-gcc a.c -emit-llvm -use-gold-plugin -Wl,debug I got ld: error: cannot open debug: No such file or directory collect2: ld returned 1 exit status I do not know why this is happening.

Hi, I found some posts on the topic of whole program bitcode and gold plugin. I put lto_codegen_write_merged_modules(cg, "/path/to/output.bc") into gold-plugin.cpp all_symbols_read_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

Hi, I am trying to load another bytecode file in one pass. I checked the opt.cpp, it uses following to load a bytecode file: ... LLVMContext &Context = getGlobalContext(); ... SMDiagnostic Err; // Load the input module... std::auto_ptr<Module> M; M.reset(ParseIRFile(InputFilename, Err, Context)); ... My question is in the runOnModule method where I want to load

Hi there, I compiled clang+gold using a gcc under path /s/gcc-4.3.1/bin/. Later on I do configure and make for flex-2.5.35, and the following command is invoked: "/path/to/my/gold/ld" --hash-style=gnu --no-add-needed --eh-frame-hdr -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 -o flex /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../crt1.o

Hi there, I am doing: opt -print-memdeps ./test.bc -analyze -globalsmodref-aa by adding globalsmodref-aa, I am hoping that globalsmodref alias analysis will be used. However, it does not turn out to be so. I found this out by adding some "errs() << " into the source code for that alias analysis. So my question is what should I do to let memory dependency analysis use

Hi, I found the following at http://llvm.org/docs/SourceLevelDebugging.html#ccxx_frontend: if (MDNode *N = I->getMetadata("dbg")) { // Here I is an LLVM instruction DILocation Loc(N); // DILocation is in DebugInfo.h unsigned Line = Loc.getLineNumber(); StringRef File = Loc.getFilename(); StringRef Dir = Loc.getDirectory(); } Does this also
