My host is Linux on x86. I configure LLVM with Clang using “–enable-targets=arm”, build it, install.
I use it as “clang -ccc-host-triple armv7-unknown-linux-gnueabi /root/tes.c”. Clang can’t find as and ld.
When I use it as “clang -ccc-host-triple armv7-unknown-linux-gnueabi -S /root/test.c”
clang: warning: unknown platform, assuming -mfloat-abi=soft
How can I use Clang to compile for the target ARM-Cortex-A8 on my host.
thank you all
Try to generate IR (-emit-llvm) and then compile with llc:
$ clang -ccc-host-triple armv7-unknown-linux-gnueabi -emit-llvm
/root/tes.c (-I gcc arm includes -L gcc arm libs) -o tes.bc
$ llc tes.bc -o tes.s (some more options)
And continue with codesourcery gcc from then on.
Or maybe you can find your way around all the options that will make
clang drive the compilation process through the correct path...
Maybe someone else knows a better way of doing this...

Thank you very much. I’ll try llvm in another part of our system. If I get time, I’ll patch clang/llvm. Thank you, whatever.
