similar to: [LLVMdev] Error while compiling .cpp

Hi, Actually I started with hello.cpp povided as an example pass and modified and made my pass which does randomization. I have been working on it and running over programs and it always worked fine but now lately i had checked out a newer version (llvm)which i believed was working fine too but now as i did some modifications and tried to compile my pass i got these errors. My pass simply

Thanks a lot for replying. I would check my system gcc configuration. I got very useful replies from dev list regarding my earlier question but yet not able to determine block size. That I want in total size of a block in a function in bytes and not just the number of instructions.LLVM Tool gives most of the information e.g function bytes etc....but not individual block. Thanks Tanu Chris

Thanks for the reply. I wish to compile without optimizations ( the option being turned off ) but still generate bytecode file. Options -S , -c removes optimizations but I also need .bc file to experiment and use further. How should I do it?

Passing "-Wa,-disable-opt -Wl,-disable-opt" will disable *all* cleanup and optimizations

Thanks !! But if i generate a .bc file like this and then run my pass over it like this : opt -load /home/llvm-cvs/llvm/Debug/lib/LLVMHello.so -hello <helloprog.bc> class_prog.bc Will the new .bc file (class_prog.bc) be also without optimizations ?opt also does some optimizations.Can I control them ?

Hello, I'm trying to create a pure LLVM toolchain (that will not depend on GNU and produce GNU-free code too) on a musl based distribution. For now, I use gcc to bootstrap and build all LLVM components. I do it individually because I was running out of space and memory trying to build all using LLVM_ENABLE_PROJECTS. Also, I don't want to create a all-in-one package. Then, once

Hi, I'm trying to compile some apps with the new llvm-gcc4 on amd64 linux to .bc files, rather than to the native code. The same process I used to build those apps before with llvm-gcc3 doesn't work: 1) export CC=llvm-gcc CXX=llvm-g++ CFLAGS="-g -fno-inline" CXXFLAGS="-g -fno-inline" 2) cd <whatever-app>; ./configure 3) make CFLAGS+=-emit-llvm

What I meant to say was that it worked for me on OS X on a slightly older version of LLVM. Anyway, here's the ld line: "/usr/bin/ld" -export-dynamic -z relro --hash-style=gnu --build-id --eh-frame-hdr -m elf_x86_64 -shared -o /home/kfischer/julia/deps/llvm-svn/build_Release+Asserts+Sanitize/Release+Asserts/lib/

Unless I'm missing something, the problem lies directly with the fact that you are trying to do a link-stage operation with the GCC frontend. GCC, by default, probably runs "ld" or another system linker, which grabs the executable from binutils. This linker hasn't been modified (yet) to include support for .bc files, but you're compiler is emitting byte code to the *.o files.

Yeah, it's not linking the runtime because you're building a shared library. This is totally ok. In this case there are undefined __asan_* symbols that are resolved when an instrumented binary loads your library. What's wrong here is that some flag passed to ld prevents it from creating undefined symbols (--no-undefined?). This flag must be removed when building with ASan. This

Indeed, removing that flag works fine, the only question is why this is added in tools/llvm-shlib/Makefile in the first place then and what to do about it: ifeq ($(HOST_OS), $(filter $(HOST_OS), Linux GNU GNU/kFreeBSD)) # Don't allow unresolved symbols.

The machine is a Dell workstation with xeon processors. The OS is RHEL 4 AS x86_64 gcc version is 3.4.6 I checked out the llvm-gcc from svn, configured with ../llvm-gcc/configure --prefix=$HOME/llvm-gcc-install --enable-llvm=$HOME/llvmobj/ --enable-languages=c,c++ --enable-checking --disable-shared --disable-multilib and get the following error message: make

gcc 3.4.x builds LLVM incorrectly on x86_64. gcc 4.0 will get you much farther, but the llvm-test regression tests still have massive problems.

Hello there, I'm building a Linux distribution based on musl and LLVM as default toolchain (including lld/libc++/libc++abi/libunwind rather than GNU). For most of the time this works pretty well. However I'm having troubles with few packages, webkit for instance fails because of max_align_t being redeclared in musl's stddef.h I see that stddef.h is provided by both musl and in the

Hi everyone, -r136747 of llvm-gcc (and possibly others) is apparently tickling a binutils issue on linux x86-64 Has anyone seen anything like this?

Actually it only link the shlib fine. Linking any executable against it fails: llvm[2]: Linking Release+Asserts executable llvm-lto (without symbols) /home/kfischer/julia/deps/llvm-svn/build_Release+Asserts/Release+Asserts/bin/clang++ -fsanitize=address -O3 -Wl,-R -Wl,'$ORIGIN/../lib' -L/home/kfischer/julia/deps/llvm-svn/build_Release+Asserts+Sanitize/Release+Asserts/lib

Hi? I am a beginer. And I want to try this searcher. When I configure and building Xapian-bingdings, I met this problem. I type "make" then got some error info: That appear like this: jack at jack-desktop:~/SE/xapian-bindings-1.2.5$ make make all-recursive make[1]: ?????? `/home/jack/SE/xapian-bindings-1.2.5' Making all in python make[2]: ??????

Hi all, after reading and learning much more about GNU's configure and compile machine than I ever wanted ;-), I arrived at configuring llvm-2.2 like this: CFLAGS=-m32 CXXFLAGS=-m32 ./configure --prefix=$HOME The assembler errors are finally gone (phew!, and thanks for all the help!), but I get linker errors now: llvm[3]: Linking Release Object Library LLVMX86.o llvm[3]: Compiling
