Hi, I'm using compiler-rt to build the library to replace libgcc. How can I disable -lgcc being added and passed to the linker? When I use: "clang -ccc-gcc-name arm-cross-g++ hello.c -Lmypath -lmylib -v" -lgcc is always added: "...gcc/arm-none-linux-gnueabi/4.6.1/collect2 ... /tmp/hello-Pj9QxO.o -lgcc ..." How can I disable or override libgcc from the command line?

Nick, How exactly do you envision this being done? Looking at the contents of config/darwin.h, I see... /* Support -mmacosx-version-min by supplying different (stub) libgcc_s.dylib libraries to link against, and by not linking against libgcc_s on earlier-than-10.3.9. Note that by default, -lgcc_eh is not linked against! This is because in a future version of Darwin the EH frame

Hi, I am trying to compile R-2.2.1 on Solaris 2.9 with a 64-bit build. Following the instructions in "R Installation and Adminstration", I changed the following settings in "config.site": CC="gcc -m64" F77="g77 -64" CXX="g++ -m64" LDFLAGS="-L/usr/local/lib/sparcv9 -L/usr/local/lib" But I got the following error messages:

1 hour ago I downloaded llvm-3.6.0-rc4-win32.exe from http://llvm.org/pre-releases/3.6.0/ . I tried to compile simple C code that just print "hello" , but it didn't compile , because clang.exe can't find . when I use clang-cl.exe with the same code , it worked . I also have the same problem with clang++ even with , I add -I flag to GCC (4.9.1) C++ headers , the result:

We develop software and are beginning a slow transition from 32 bit applications to their 64 bit equivalents. During this period it will be necessary to build programs targeted for both environments using the x86-64 machines for development. here is a simple/small "application", sizes.c: #include <stdio.h> #include <stdlib.h> int main(int argc, char **argv) {

Hi, I'm trying to link my objs with compiler-rt built runtime lib for arm. According to the compiler-rt doc, it should be able to replace libgcc. However, if I replace "-lgcc" with "compiler-rt.a" for a static linking, gcc linker complains about undefined functions. Using "nm -g", I compared the functions in libgcc and compiler-rt.full-arm.a and found there are

Sorry for not explaining well.

Initially, tt was not a problem with the verifier, we were just inserting a wrong instruction in our pass. Also we were able to figure out the error you pointed out and our pass is running as intended!!! Thanks a lot.

I was able to solve that but still crashing with the same error saying "Unreachable executed". I have attached the output with this mail. Thanks in advance.

I have attached the output with this mail. This time you've got: %1 = load i32** getelementptr inbounds ({ i32* }* @structobj, i64 0, i32

Yes. Intially the pass was crashing when the module when the module verifier was running. I was able to solve that and now it is crashing when the bit writer pass is running.

Hi, I'm currently working on one of my team's project to build LLVM full clang toolchain (Clang, libcxx, libcxxabi) on a CentOS machine. Previously we compiled our codebase with llvm-toolset-7/clang++, which by default takes stdlibc++ to compile and link. And now we'd like to switch to use LLVM clang with libc++. I have built libc++ and libc++abi from source (5.0.1 release) and set

Is the new EH scheme completely compatible with the existing linker in Xcode 4.1? I am finding that today's changes break the ability to link xplor-nih with dragonegg under FSF gcc 4.6.2... de-g++46 -c thread.cc -O3 -ffast-math -funroll-loops -g -DX_MMAP_FLAGS=0 -DFORTRAN_INIT -fno-common -DDARWIN -D_REENTRANT -DNDEBUG -I/Users/howarth/xplor-nih-2.27/vmd/

Hi everyone, I am trying to add some optimizations to LLVM's PTX backend. But i am unaware of the existing optimizations. Can you please guide me about the same? Thank You:) -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20110903/bc038a07/attachment.html>

Hi, I've written a pass that basically does some code transformations to enable parallel execution of loops. After the transformation llvm runs BitCode Writer pass , which is aborting with Unreachable Executed error. I have attached the input llvm code and the output llvm code for reference. I am stuck at this problem for a few days now. Please let me know if you are able to find anything
