similar to: [LLVMdev] Automating Analysis Pass at linktime question [liblto] [safecode]

Hello, Is there any CMake variable available to build LLVM libs as static libraries. I found one -DLIBCLANG_BUILD_STATIC=ON but what if I want libLTO.a instead of libLTO.dylib ? *Vivek Pandya* -------------- next part -------------- An HTML attachment was scrubbed...

Dear LLVMers, I'm currently working on creating an alternate libLTO.so that will run some whole-program analysis and transforms of mine during the final linking of an executable. The idea is for it to link all of the bitcode files together, run the regular LTO passes, and then run my passes. For Linux, I should be able to get the Gold linker to load my libLTO.so instead of the standard

Hi all, libLTO is exposing a very “stable” (in the sense of immutable) C API to be used by linkers (and binutils tools) that manipulate bitcode (like when performing LTO). I’m looking into relaxing the stability concern and design a policy for this API that would allow to deprecate and remove some the APIs exposed here. The MacOS linker (ld64) is one the users of libLTO, but there are others

Hi, We have been investigating an issue when running LTO with our proprietary linker, which links against libLTO dynamically. The issue is that when we pass -time-passes via the lto_codegen_debug_options function in the LTO C API, no time information is produced during compilation. The reason for this is that time information is stored in state owned by a ManagedStatic instance, and is only

Hi all, I just svn-updated the 2.5 branch on my machine and I noticed this warning during the build. *** Warning: Linking the shared library /home/maurice/installation/llvm/Debug/lib/libLTO.la against the non-libtool *** objects /home/maurice/installation/llvm/Debug/lib/LLVMCppBackend.o /home/maurice/installation/llvm/Debug/lib/LLVMMSIL.o /home/maurice/installation/llvm/Debug/lib/LLVMCBackend.o

I'm looking into the possibility of building the libLTO plugin on Linux, and got tangled up in the build system. Currently, tools/Makefile only includes 'lto' when the OS equals Darwin, while tools/lto/Makefile has an if-statement that builds libLTO as a static library on non-Darwin systems. If I try to build libLTO as a dynamic library on Linux, it works fine, but I get an

The path to libLTO.so in LLVMgold.so points to the build directory on my machine: % ldd /usr/local/lib/LLVMgold.so linux-vdso.so.1 (0x00007fff3d795000) /var/tmp/build_llvm_clang/Release+Asserts/lib/libLTO.so => not found libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f1703983000) ... I have configured clang with: ../llvm/configure --enable-optimized

Hi, Is there a way to avoid linking with the dynamic LTO library. I’m using llvm 5.0.0 on various platforms (linux, windows, macOS), this library is not required by my application and I keep having trouble with it. My project is cmake based and makes use of LLVMConfig.cmake or llvm-config output (depending on the platform - there is no LLVMConfig.cmake with the windows package). On windows the

Hi, I need advice in instrumenting programs using liblto and gold plugin. Specifically, I added my pass in tools/lto/LTOCodeGenerator.cpp. My pass inserts functions (myLoad and myStore) for some load and store instructions. The functions exist in a library file. I found that the approach works for the example in the link: http://llvm.org/docs/GoldPlugin.html $ llvm-gcc -flto a.c -c -o a.o $ ar q

Hi John, Thank you for your advice. LIBS and LDFLAGS work for the configure script, but they gave errors in the make stage for apache and mysql. I used either of the following ones with other flags: - export LIBS="-L/home/sangmin/Dropbox/Falcon/bin/ -ldummy" - export LDFLAGS="-L/home/sangmin/Dropbox/Falcon/bin/ -ldummy" Here are the error messages: Compile error (apache):

Dear John, Thanks for your reply. I want to do whole program analysis, all what I need are just the separate .bc files. What instructions should I follow? I run the configure on apache in this way: CC=clang CFLAGS=-emit-llvm ./configure while I get the error message like: checking for gcc... clang checking for C compiler default output file name... configure: error: C compiler cannot

Whole-program analysis requires that you link all of the individual bitcode files from different compilation unit (i.e., individual .c files) together into a single

Hi, How to compile a large project (such as Apache) by using llvm-gcc? I tried to replace CC with llvm-gcc and CFLAGS with -emit-llvm while running configure, but it didn't work. Thank you for your help. -Wink

Thanks John. Your approach worked fine for my small toy program. Now, I would like to run my module pass on a huge project (still a single executable) consisting of a few thousand bit code files scattered in many different directories. And some of them are static libraries. Do you still think it's a good idea to manually gather and link them with llvm-ld? I've seen other module pass

Hi, I want to compile apache httpd using LLVM compiler. However, I am interested in generating llvm bytecode files [.s or .ll] files along with its executables. I followed steps mentioned in link : http://stackoverflow.com/questions/13851661/compiling-apache-httpd-into-llvm-bytecode-using-clang However after following all instructions when I compile httpd with following options I get directly
