Critical Issue
Description
The Nios II GCC 4 tool chain does not support the C compiler
pragma and flag for reverse bit fields. If you try to use the compiler
pragma reverse_bitfields
, you see the following warning:
'pragma_reverse_bitfields' attribute directive ignored
Similarly, the C compiler flag -mreverse-bitfields
is
unsupported.
Resolution
Use the GCC 3 tool chain.
