MIPS Rx000

My MIPS collection includes:

MIPS OS/Software :

Linux

http://www.linux-mips.org
http://www.debian.org/ports/mips/

The www.linux-mips.org CVS version is very different from the "vanilla" kernel.org . The Linux kernel 2.4 is in deep freeze now (linux_2_4 CVS branch).

OpenBSD

http://www.openbsd.org/arc.html

The OpenBSD/arc port has been discontinued after the 2.3 release.

NetBSD

http://www.netbsd.org/Ports/
http://www.netbsd.org/Ports/arc/

FreeBSD

http://www.freebsd.org/platforms/mips.html
Dead ?

IRIX

SGI IRIX. Latest version: IRIX v6.5

MIPS CPU Emulators

mips64emul: works under with CygWin
SPIM a MIPS32 Emulator. Educational tool.
VMIPS - MIPS R3000 Emulator.
MPS - another R3000 emulator
YAMS - Yet another MIPS32 Simulator
MISSE - MIPS Instruction Set Simulator Environment

MIPS Disassembler

IDA PRO

Toolchain

I'm using Linux H.J.Lu and NIISI's toolchain with minimal modification (ver-3):

Tested on the RedHat Linux 7.3 .

[alec@on ~]$ /export/tools/bin/mips-linux-gcc -v
Reading specs from /export/tools/lib/gcc-lib/mips-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113.2)

ToDo: Toolchain for the Cygwin.

HOWTO compile a standalone

Tips&hints:

This toolchain is based on the Linux kernel headers. To compile a standalone assembler application you should define: -D__ASSEMBLY__ -D__KERNEL__

To use another #include set (i.e. NetBSD's #includes) use: gcc -nostdinc -I. -I/NetBSD/src/include

For the NetBSD's #include you should define: -Dlint -D_STANDALONE -DNO_ABICALLS -D_LOCORE -D__NO_LEADING_UNDERSCORES__

There are two common extensions for the assembler sources: *.s and*.S . The difference is in the preprocessor only -- the .S extension will be preprocessed by the cpp, so you can use #define , #include e.t.c. in the .S file.

There is no MIPS assembler directive to define an absolute code addresses (like .org). You should use ld options to define starting point and absolute address: ld -T 0x80010000 --entry=start . The "start" symbol must be defined as .globl start in the .text segment.

To define an absolute constant use:

    	.globl symbol
symbol  = 0x80000180

By default, the ld produces MIPS ELF object format. To make an ECOFF file from the ELF you should use: objcopy -O ecoff-littlemips prog.elf prog.ecoff

To compile a standalone c sources, use: gcc -mno-abicalls

You should provide a minimal "POSIX environment" for the C if you have a main () {}; function in the program to emulate a crt1.o
