Subject: sim: ppc: drop natural types
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=03b46de59084f558140b632f0868a7e37b7749d3;p=binutils-gdb.git

sim: ppc: drop natural types

These are almost entirely unused.  For the very few places using them,
replace with explicit signed types.  This matches what was done in the
common sim code.
