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. </p> <p> So I shall close this request. It can be reopened if such an architecture becomes feasible in the future. </p> <p> Jeremy </p> <p> -- <br /> Tel: +44 (1590) 610184<br /> Cell: +44 (7970) 676050<br /> SkypeID: jeremybennett<br /> Email: <a href="mailto:jeremy.bennett@embecosm.com">jeremy.bennett@embecosm.com</a><br /> Web: <a href="http://www.embecosm.com">www.embecosm.com</a> </p>
