+- clang only supports global register variables when the register specified
+ is non-allocatable (e.g. the stack pointer). Support for general global
+ register variables is unlikely to be implemented soon because it requires
+ additional LLVM backend support.
- clang does not support static initialization of flexible array
members. This appears to be a rarely used extension, but could be
implemented pending user demand.
