Subject: PATCH: minor hppa disasm cleanup
Date: Thu, 01 Jul 1999 00:00:00 -0000 [thread overview]
Message-ID: <199906011505.LAA08672@wmtl249c.us.nortel.com> (raw)
In the pa disassembler, the 'E' code is always used for 0x0C opcodes
where only left register halves occur. So the L/R selection bit at 25
is always 0 and the test isn't required.
This is patched against 990413, since I can't use cvs to update my
snapshot (restrictive firewall) and this is the last one I have.
Changelog entry:
Tue Jun 1 11:03:02 EDT 1999 Jerry Quinn <jquinn@nortelnetworks.com>
* hppa-dis.c (print_insn_hppa): Remove unnecessary test in 'E'
code.
