---++ Summary
Nolimips is a MIPS-based simulator with "infinitely many registers". It consists of an assembler which reads MIPS assembly code, and of a virtual machine which executes the instructions processed by the assembler. For the moment Nolimips does not produce nor execute binary code, but ELF writer and loader are planned.
The main purpose of Nolimips is to help students of compilers courses to evaluate the output from their "high-level language into MIPS assembler code" compilers, before and after register allocation.
Its main features are:
- minimal support of MIPS instruction set,
- built-in system calls (string printing and reading, etc.),
- unlimited registers ($x0, $x1, etc.),
- gdb-like interactive shell.

Nolimips has been initially written by Benoît Perrot <benoit (AT) lrde.epita.fr> and maintained by the Tiger Project team since.
