[cfe-dev] [release_34] [compiler_rt] dataflow tests using -m64 on i586

[İsmail Dönmez]

Hi,

Following DataFlowSanitizer tests are using -m64 on i586 and causing header
problems:

     DataFlowSanitizer :: basic.c
     DataFlowSanitizer :: custom.c
     DataFlowSanitizer :: flags.c
     DataFlowSanitizer :: fncall.c
     DataFlowSanitizer :: propagate.c

And the error is:

 In file included from
/home/abuild/rpmbuild/BUILD/llvm/projects/compiler-rt/lib/dfsan/lit_tests/propagate.c:7:
 In file included from
/home/abuild/rpmbuild/BUILD/llvm/stage2/bin/../lib/clang/3.4/include/sanitizer/dfsan_interface.h:18:

 /usr/include/gnu/stubs.h:10:11: fatal error: 'gnu/stubs-64.h' file not
found
 # include <gnu/stubs-64.h>

Of course 64bit headers are non-existent on 32bit. If possible I suggest
using -ffreestanding option for these tests.
