Or1ksim should support the SR LEE bit

Information:
Type :: REQUEST
Status :: CLOSED
Assigned to :: Jeremy, Bennett

Description:
Originally noted by Shinji Wakatsuki 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.

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.
