MIPS 64 emulator

[Carter]

I am experimenting with a project which requires I map things directly
into MIPS machine code. Are there good emulators available which might
be good to test with before I try the system on the gdium?

Thanks,

Carter.

Hi,
I think qemu can meet your requirement for its malta emulation is very mature.

Thanks for the reply. I have been thinking a bit more about my goals
w.r.t. this and perhaps since I will be testing my compiler on a more
powerul desktop Intel machine (I suspect repeatedly compiling the
software on the gdium would be quite time consuming). In this
situation I probably just need some sort of tool or disassembler which
produces MIPS 64 assembly. I do however have a few more questions
which I would be grateful if I could get some answers to-

1) is the MIPS 64 supported by the Loongson 2/F essentially release 2
or are there some differences?
2) is n64 the correct ABI to use?

Thanks in advance(any help is appreciated),

Carter.

The Loongson implements the MIPS3 instruction set, which is a subset
of the MIPS64 instruction set published by MIPS. It also has some
extensions. See the Loongson manual for details.

I would recommend the N32 ABI.

Is there an English manual somewhere? My chinese is not that good. The
link from linux-mips to the english manual seems to be broken.

Hi Carter,

You can find all the Loongson 2F manuals on the Wiki, but I've archived
most of the manuals in a tarball at:

http://lebesgue.cowpig.ca/~philippe/gdium/gdium-manuals.tar.bz2

Cheers,
Phil

PS: the wiki, in case you haven't seen it, can be found at

Sorry for the late reply. Thanks for the help. Hopefully I can put the
information to good use.
