Hi Rafael, I've tried the LTO options with dragonegg, but I haven't had any luck getting it to work, I'm not sure if it is related to my installation of gold or my gcc configuration. I'm really interested in getting the resulting program as bitcode though. Will LTO do that for me? What I'm trying to do is build a bitcode version of libc that I can combine with a program and

Hello, Well, I recompiled the LLVM-gcc .../llvm-gcc4.2-2.6.source/configure --prefix=`pwd`/../install --program-prefix=llvm- --enable-llvm=/home/LLVM/llvm-2.6/ --enable-languages=c  --disable-libssp  --with-gnu-ld=/home/LLVM/llvm-gcc4.2-2.6.source/arm-elf-ld --with-gnu-as=/home/LLVM/llvm-gcc4.2-2.6.source/arm-elf-as  --with-cpu=cortex-a8  --target=arm-elf Everything is OK, but when trying

OK, thank you. Are there some pre-built X86 binaries for LLVM-gcc for ARM? It yes, where can I download from?

Eli, Hm. There's a test in (CodeGen/X86/call-imm.ll) which uses darwin with relocation model static. It expects to use call-to-immediate. Is this in error?

Do you have an ARM libc? You should configure llvm-gcc with --with-sysroot pointing to the libc install directory. If you are building from scratch, you have to *) Build binutils *)

For some time now I was curious on what the size impact of LTO was. I decided to test this with a large C++ app, clang was a natural choice. With PR8313 fixed with the proposed patch and PR8300 avoided by disabling constructor aliasing I was able to hack clang to bootstrap with LTO enabled using the gold plugin. I did the testing on linux x86-64. Gcc is the 4.4.4 included with Fedora 13. The

So, if I understand you correctly the summary is that doing * Build llvm and install it in /foo/bar * Build llvm-gcc and install it in /foo/bar * export PATH=/foo/bar/bin:$PATH * Build llvm again in a unrelated build directory and then running "make check-lit" in the second directory causes /foo/bar/bin/llc and similar tools to be used instead of the recently build tools? If that is

They do work if you have GraphViz binaries in your path when you configure LLVM.
