Some tests with valgrind also work. My next try is to add some debug code to do bounds checking in SmallVector.

For some time now the gold linker has support for plugins and llvm has a plugin for it. Unfortunately, it was still not possible to do fully transparent LTO on linux because ar had no support for plugins and a library created with llvm files in it would have no symbol table and would be rejected by gold. Today support for plugins has been committed to BFD. That is the file format abstraction

Hello, I am trying to bootstrap on ARM linux EABI using a qemu chroot to better test my changes on at least one more architecture. I am using the following configure line: ../gcc/configure --prefix=/home/espindola/install/ --program-prefix=llvm- --enable-languages=c --disable-shared --disable-multilib --enable-llvm=/home/espindola/build --enable-checking arm-linux-gnueabi The bootstrap fails

Yes,it's indeedly the correct one,and new ld can also support -plugin option,I don't know the reason of the trouble, 2009/9/17 Rafael Espindola <espindola at google.com> > > llvm-gcc -use-gold-plugin a.a b.o -o hello > > > > which is similar with the example in the document,it tells me that > > libLLVMgold.so can not be found ,but I truly put it in the

I was trying to reduce a test case, but it is a bit hard. I have a cpp that crashes cc1plus,

Hi,all I'm using ubuntu8.04 and I'm installing gold-plugin along with the document of that, After I built the binutils and LLVM with plugin enabling,and I also replace ld with ld-new which supports plugin,I tried to compile a hello world program by this: llvm-gcc -use-gold-plugin a.a b.o -o hello which is similar with the example in the document,it tells me that libLLVMgold.so can not

Thanks! I tried the same with the llvm-gcc-4.2 mirror, but "git svn rebase --local"

In order to the code generators to lower functions arguments that have the "byval" attribute, they would have to access the original argument Type. For example, on linux x86_64 {i64, i64} should be passed on registers and {i64, i64, i64} goes on the stack. The problem is that when looking at (for example) FORMAL_ARGUMENTS, the only thing that is present is the type of the pointer itself

Hi, I am new to LLVM and have been trying to get it working on scratchbox (ARM target). When I try to build llvm-2.1, the build freezes with the following output.. /scratchbox/compilers/arm-softfloat-linux-gcc-3.4.4-cs-2005q3-2-glibc-2.3.6/bin/sbox-arm-softfloat-linux-gnu-nm: 'libgcc/./_dvmd_lnx_s.o': No such file mv -f libgcc/./_dvmd_lnx.visT libgcc/./_dvmd_lnx.vis

I get the error below (and have for a couple weeks now) when trying to build llvm-gcc on Ubuntu Feisty. In the meantime, on Ubuntu Gutsy, everything has been building fine. Both are release builds for x86. John cc1: StringMap.cpp:177: void llvm::StringMapImpl::RemoveKey(llvm::StringMapEntryBase*): Assertion `V == V2 && "Didn't find key?"' failed.

Dear All, Currently the load of llvm.org is too high. This influences the whole project services like buildbots, bugzilla, etc. It was found that this workload is possible caused by massive mirroring of LLVM SVN repository into git/hg/whatever. Please don't do that :) 1. Usually one don't need full history, this makes the mirroring much easier and faster (do you *really* need r5000? I

Hi Duncan, 53950 bootstraps for me on x86_64-unknown-linux-gnu. Are you able to isolate this at all?

Rafael, Remember that the qemu <= 0.9.0 can misexecute code compiled by LLVM. I think you should test using qemu CVS.

I have been playing a bit with LLVM again and it looks like the current major missing feature on Linux x86-64 is PIC. Is anyone working on it? If not, I would like to do so. I have the ABI documentation (http://www.x86-64.org/documentation/abi.pdf), but would be glad if someone had some LLVM specific pointers. For example, from the targets that do have support for PIC, which one is the one to be
