- Subject: [patch] Add fido support (Part 6/n)
Hi,
Attached is the sixth in a series of patches to add fido support to
binutils.
This patch adds two new movec registers. movec registers are control
registers that are accessible only through the movec instruction.
Tested by building binutils and newlib, which already uses these
registers. OK to apply?
