Build llvm-gcc exactly the same way you're building the cross gcc for your target. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State

Sorry for not explaining well. After compiling with g++-cross g++-cross -c a.c I do link using this command /gold_binutils/build/gold/ld-new -plugin ~/Desktop/Sanjeev/LLVM/llvm-2.7/Release/lib/libLLVMgold.so --eh-frame-hdr -melf_i386 -dynamic-linker /lib/ld-linux.so.2 /usr/lib/crt1.o /usr/lib/crti.o /usr/local/lib/gcc/i686-pc-linux-gnu/4.2.0/crtbegin.o

I suspect that my llvm-gcc cross compiler is using the wrong assembler because it does not recognize "-mcpu=cortex-a8". I was trying to build a cross compiler for a Mac host. Now I am trying to build on x86_64 Linux. I am targeting a Beagle board with an ARM Cortex-A8 and Angstrom Linux. TRIED: to use the script in llvm/utils/crosstool/ARM/build-install-linux.sh I used the recommended

Hello Evan and Robert I have been investigating the unexpected test failures from the ARM nightly builders in order to get a better picture why the ARM backend don't pass the whole testsuite: I have run the failing tests manually on my arm board and can now categorize most of the thirteen unexpected CodeGen failures in four categories: 1. llvm don't lower MVT::i64 properly on arm

Questions about the port of Xen to ARM with virt extensions are best posted to xen-devel, the xen-arm list focuses on the PV port. Adding xen-devel since it seems you are mainly asking about the w/-virt-extensions port.

hi all I saw that llvm-2.7 support arm cortex-a8 now, but I didn't find how to cross build it. thank you all -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20100505/976c140e/attachment.html>

hi all I use --enable-targets=arm configure LLVM, build it with Clang, but when I using Clang, it say: #clang -triple /root/a.c error: unable to create target: 'No available targets are compatible with this triple, see -version for the available targets.' 1 diagnostic generated. How can I use Clang generate code for ARM Cortex-A8? thank you -------------- next part

Hi, Just to clear things up... So 1.1 has some new analysis code that increases the amount of CPU. When building as floating point (which you appear to be doing, right?), the new code is enabled at complexity 7 and up (opusenc defaults to complexity 10 IIRC). This is why you've been seeing an increase in the CPU time. In version 1.0.x, complexity 5-10 are the exactly the same for music.

I wrote: > In a floating point build > it's enabled only at complexity setting 10 Sorry. I meant that in a _fixed_point_ build the new analysis code is enabled only at complexity setting 10. It's currently enabled for floating point builds at complexity 7 or higher. Both fixed and float builds default to complexity 9 in 1.1. -r

LLVM ARM v6 backend is in fairly good shape. Even the JIT passes nearly the entire llvm test suite. There are some known missing bits: 1. Exception handling 2. Atomic Not sure: 3. Debugging support (should be trivial to hook up if it's not done) Also the thumb backend is not awesome. Its performance is not great.

I am trying to compile llvm-gcc for an ARm target. I usine the following configure options: /home/tony/llvm/llvm-gcc/configure --prefix=/home/tony/llvm/llvm-gcc-install/ --program-prefix=llvm-arm- --enable-llvm=/home/tony/llvm/llvm-install/ --enable-pic --disable-bootstrap --target=arm-none-linux-gnueabi --enable-languages=c,c++ Then I try to make: make ENABLE_PROFILING=1 ENABLE_OPTIMIZED=1

Thanks for everyone giving their feedback! I saw pretty unanimous support for making -mcpu=generic the default and making -mcpu=generic schedule for an in-order CPU (Cortex-A8 in this case). I'll be making those changes shortly. I think the comments also make clear that it's less obvious whether we'd want -mcpu=native to become a default. It's probably good for some use cases, but

Hello, I am trying to cross compile LLVM. Build and compile on Mac OS X 10.5.7 Target is an Angstrom Linux Cortex-A8 Beagle board. I would like to avoid GPLv3. I can compile. But when I run my executable on Beagle crt0.S is calling an AngelSWI to setup the heap and stack. But the AngelSWI seems to just be a stub because it returns zeros for the pointers. That leads to a segfault. If I hack in
