I checked that it still builds correctly on linux.

With this patch, it seems that it produces a file named LLVMgold.so instead of libLLVMgold.so.

The problem is that we build

Hi all, I got an error from the gold plugin example in the following link: http://llvm.org/docs/GoldPlugin.html#example1 Here is the error message: sangmin at sangmin-desktop:/tmp$ llvm-gcc -use-gold-plugin a.a b.o -o main /usr/bin/ld: error: a.a: no archive symbol table (run ranlib) /usr/bin/ld: /usr/lib/crt1.o:(.text+0x18): error: undefined reference to 'main' /usr/bin/ld: b.o: in

Hi, I fixed error by using different version of ld with LLVM 2.7. I used ld.gold that comes with Ubuntu 10.04. Here is the version info: sangmin at sangmin-desktop:/tmp$ ld -v GNU gold (GNU Binutils for Ubuntu 2.20.1-system.20100303) 1.9 My experience of gold plugin is as follows: LLVM 2.7 (with libLLVMgold.so) + ld 2.20.1 (from Ubuntu 10.04) : O LLVM 2.7 (with libLLVMgold.so) + ld 2.21.51

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, 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 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):

Hi, all. I want to get the single bitcode file after link-time optimizations. After doing some searching, I get commands as follows: *llvm-gcc -O4 -c xxx.c -o xxx.o llvm-gcc xxx.o -use-gold-plugin -Wl,-debug -Wl,-plugin-opt=also-emit-llvm -lm -o xxx* But these command don't give me the wanted bitcode file. The used version of llvm is 2.7. Do you have any idea of this problem or any other
