            Bug ID: 30467
           Summary: Remote old LLVM_GNUC_PREREQ checks now that GC 4.7 is
                    the minimum
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: pete.cooper at gmail.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

Looking in the LLVM codebase, specifically Support/Compiler.h, there are checks
such as:

#if __has_attribute(sentinel) || LLVM_GNUC_PREREQ(3, 0, 0)
#define LLVM_END_WITH_NULL __attribute__((sentinel))
#else
#define LLVM_END_WITH_NULL
#endif

As we require GCC 4.7 as a minimum
(http://llvm.org/docs/GettingStarted.html#software), we should remove any
checks which are no longer required.
