        <pre>Created <span class=""><a href="attachment.cgi?id=13288" name="attach_13288" title="the patch file for compiler-rt/lib/sanitizer_common/santizer_platform_limits_posix.h">attachment 13288</a> <a href="attachment.cgi?id=13288&action=edit" title="the patch file for compiler-rt/lib/sanitizer_common/santizer_platform_limits_posix.h">[details]</a></span>
the patch file for
compiler-rt/lib/sanitizer_common/santizer_platform_limits_posix.h

I got this problem during the build of llvm git source tree. Just during the
build of sanitizer_platform_limits_posix.cc.o in compiler-rt, the error rise
for wrong CHECK_TYPE_SIZE(__kernel_old_gid_t).

  after dig into the source code, I find in the line #472 in
sanitizer_platform_limits_posix.h has been changed since the end of September.
The aarch64 don't use "unsigned int" for __sanitizer__kernel_old_git_t, but
change to "unsigned shot".

  I just put this line back to the same as 3.5.0. The problem solved.
