[cfe-dev] clang cannot compile ARM assembly in libcxxabi/src/Unwind ?

[İsmail Dönmez]

Hi,

Trying to compile libcxxabi on ARM/Linux with clang ToT, I get:

cd /home/ismail/libcxxabi/build/src/Unwind && /havana/dist/llvm/bin/clang
 -D_DEBUG -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS

-fdata-sections -I/home/ismail/libcxxabi/include
-I/home/ismail/libcxx/include    -UNDEBUG -fPIC -o
CMakeFiles/unwind.dir/UnwindRegistersRestore.S.o   -c
/home/ismail/libcxxabi/src/Unwind/UnwindRegistersRestore.S

This works with the gnu as (tested using -no-integrated-as). Is this a
known problem?

Thanks!
