[cross-debug or cross-endianess or byte-swapping]
I suppose you could encode a whole bunch of stuff into the current
readmem()'s "error_handle" flag. It only uses 3 bits now, and it seems
that there would only be a need for one readmem(), which could do all manner
of different things based upon the byte-swapping or whatever flags,
all of which could be conditionally no-op flags for non-cross-compiled
versions.
There's patch from Corey Minyard that changes the ULONG etc. macros to
handle endianess. It's for ppc-on-x86 cross-debug and against an old
version of crash, you can get it from the wayback machine:

Using readmem you need to read long/short values one-by-one anyway
unless you have a list of data with the same type. IMHO the ULONG
approach is simpler and clearer (makes code more readable). It's some
work to have all memory accesses use ULONG etc. but you might have to do
the same with the readmem approach.
