[GXemul-devel] MIPS TGEIU etc., NetBSD/evbmips 8.0 (Malta)

[Anders G. <ga...@gm...>]

The patch which was applied from
http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/emulators/gxemul/patches/patch-src_cpus_cpu_mips.cc?rev=1.1&content-type=text/x-cvsweb-markup&only_with_tag=MAIN
("implement trap with immediate instructions present in MIPS32.") for the
MIPS TGEIU instruction recently is wrong; it decodes the trap instructions
similar to BGEZALL etc. which are branches, not traps.

The disassembly has now been fixed, and the instructions have been actually
implemented too (but not that well tested in the Trapping case).

This finally allows the NetBSD/evbmips installation instructions to be
updated from 7.1.2 to 8.0, since 8.0 used one of those instructions during
bootup.
