Subject: Endianness: Make it easier to check the compiled in guest endianness.
X-Git-Tag: stable_2012_02_02~74
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3eca0a2bc9d8679a05dd92b5aec6e6358aab3681;p=gem5.git

Endianness: Make it easier to check the compiled in guest endianness.

It was technically possible but clumsy to determine what endianness a guest
was configured with using the state in byteswap.hh. This change makes that
information available more directly.

Also get rid of unused (and mildly redundant) ByteOrderDiffers constant.
