Hi, I cross-compile llvm/clang. The build platform is x86_64-linux-gnu. The host platform is mips-linux-gnu. Llvm and clang built successfully but "make install" shows the following error: % make install llvm[0]: Installing Release+Asserts /home/simon/work/install/clang/bin/llvm-tblgen strip: Unable to recognise the format of the input file

As you might see - these are at least 3 years old and are known to be heavily buggy on ARM.

The necessary fixes were *not* pushed into the binutils 2.20.1 release. You should grab so-called development snapshot (aka 2.20.51). Make sure it's recent (say, after January 2010). PS: Note that gold is

Hello, Thanks for the reply. We have an product whose one part has lot of algorithms doing some graphics work. Our intention was to figure out if there can be any performance gain if we use llvm instead of native ARM. This is for ARM target. Earlier, I have built this component using llvm and tested it on x86. Performance was 4x as compared to native gcc. Then I built llvm for ARM and tested

Sorry I used --enable-pic, not --enable-pics. It was a typo.

> But I wanted to say is using these binutils I have built a llvm compiler for > our ARM target. That's correct. Mostly because gcc is using pre-UAL ARM assembler syntax and LLVM switched fully to UAL one. Also, UAL is needed for correct Thumb-2 support, etc. So, in short: gcc is generating some subset of ARM assembler and thus gas is bug-free. LLVM generates somehow different subset and

Sorry again, my bad. I actually was using --enable-pics instead of --enable-pic. Now LLVM is being compiled. Hope the last phase llvm-gcc compilation would be a success. Thanks a lot.

Sorry about that. As you can see, I'm using binutils (ld & as ) from arm toolchain we use to build things for our target. arm_a_b_c_ld -v gives 2.17.50.20070611 arm_a_b_c_as -v gives 2.17.50.20070611 Do you belive that older binaries of (linker & assembler) can cause performance drop ? Unfortunately I'm not in a position to update the arm compiler for my company :) On Mon, Jun

Hello > exec: 2: -meabi=4: not found > make[4]: *** [crtbegin.o] Error 1 It seems you don't have cross-binutils for arm-eabi installed. Note that ARM binutils are known to be buggy - you should use the fresh CVS snapshot.
