Subject: [Gc-linux-devel] Gekko binutils patch
Date: Sun, 2 May 2004 19:11:02 +0300 (EET DST)
Hi, this is a in-progress patch for adding support for the Gekko
instructions to binutils (as and objdump). It's not well-tested at all,
and it's incomplete because the load and store instructions are still
missing because I don't really understand their encoding (eg. what do the
W and I fields represent?)
The patch is against current CVS, and any help testing/fixing/whatever is
appreciated.
To assemble Gekko instructions, pass "-mgekko" to as, and to disassemble
them pass "-Mgekko" to objdump.
-Anders
