OpenRISC 1000
Or1ksim should support the SR LEE bit #42

Originally noted by Shinji Wakatsuki swaka@hdlab.com
Or1ksim ignores the Supervision Register Little Endian Enable (LEE) bit. The model will always be big-endian in its standard build. Currently the only way to get round this is to build a big-endian model by setting the flag OR32_BIG_ENDIAN.
This is a feature request to add support for the SR LEE bit.
This is a non-trivial piece of work, and there are concerns about the performance impact of dynamically checking the endianism.

<p>
Although the bit is recorded as being writeable in the architecture manual, I do not anticipate any implementation that could dynamically switch from big-endian to little-endian.

So I shall close this request. It can be reopened if such an architecture becomes feasible in the future.
