Subject: sim: accept -EB/-EL short options
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=21b9b99cd797fd2581ed559b89ec0c2cc6e87edf;p=binutils-gdb.git

sim: accept -EB/-EL short options

Many GNU tools accept -EB/-EL as short options for selecting big &
little endian modes.  While the sim has an -E option, it requires
spelling out "big" and "little".  Adding support for -EB & -EL is
thus quite trivial, so lets round it out to be less annoying.
