Package: clang-3.3
Severity: important
Tags: patch upstream
Hi,
clang-3.3 does not currently define the GNU/kFreeBSD pre-processor
macros (such as __FreeBSD_kernel__) because it is missing the TargetInfo
object class for this platform. This breaks software
that attempts to use these macros to identify it.
See upstream bug http://llvm.org/bugs/show_bug.cgi?id=17104
The patch for clang-3.3 is slightly different than the one submitted
upstream for trunk. See attachment.
