            Bug ID: 24214
           Summary: Clang crashes with the regparam function attribute
                    when targeting AArch64
           Product: clang
           Version: trunk
          Hardware: PC
                OS: FreeBSD

Example showing the assert

The AArch64TargetInfo class sets RegParmMax to 8, however in
include/clang/Basic/TargetInfo.h there is an assert that RegParmMax < 7.

The attached file shows the issue when built with:
clang -cc1 -triple aarch64-unknown-freebsd11.0 regparam_test.c

Building this with clang 3.6 from FreeBSD and clang 3.8 I get the following:

Assertion failed: (RegParmMax < 7 && "RegParmMax value is larger than AST can
handle"), function getRegParmMax, file
/home/andrew/freebsd/repo/llvm/tools/clang/include/clang/Basic/TargetInfo.h,
line 824.
