@mipsy{} is a MIPS simulator designed to execute simple register based
MIPS assembly code. It is a minimalist MIPS virtual machine, which
allows unlimited registers.
@mipsy{} is a basic MIPS architecture simulator. 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 @mipsy does not produce nor execute binary code, but ELF writer
and loader are planned.
The main purpose of @mipsy 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 features are:
@itemize @minus
@item
sufficient support of MIPS instruction set
minimal support of MIPS instruction set
@item
illimited registers
built-in system calls (string printing and reading, etc.)
@item
unlimited registers ($x0, $x1, etc.).

@chapter Invoking @mipsy{}
To invoke @command{mipsy} run:
@example
mipsy @var{options} @var{file}
@end example
@noindent
where @file{file.s} is a simple text file, and @var{options} is any
combination of the following options:
@table @code
@item -?
@itemx --help
Display a help message and exit successfully.
@item -V
@itemx --version
Display the version number and exit successfully.
@item --usage
Give a short usage message
@item --tasks-selection
Each task of @mipsy{} (parsing, execution, etc.) comes with a set of
prerequisites: for example the pretty printing of an input program
implies the parsing of its source file. This option asks @mipsy{} to
display the tasks that must be run before to run the ones explicitly
specified on command line.
@item --parse
Parse a file.
@item --trace-scan
Trace the scanning.
@item --trace-parse
Trace the parse.
@item --fill-delay-slot
To avoid a bubble in their pipeline, MIPS processors execute the
instruction immediately following a branch; this instruction is said
to be in the delay slot (FIXME: see further). This option fills the
delay slot of branch instructions with a NOP, disabling the delay
slot, simplifying the task of assembly programmers how do not care
about writing optimized code.
@item --unlimited-regs
During last stages of a compiler, the intermediate representation of a
source file (which mainly consists in a generic, architecture
independent assembly code) is progressively translated into an
architecture dependent assembly code. Low level (but still intermediate)
representations are designed to be as near as possible of target
assembly code, but generaly consider an extended target machine with an
unlimited amount of registers. This option gives @mipsy{} the ability
to handle an arbitrary number of registers, allowing compiler
developpers to test their low level output before implementing
register allocation. These new registers may be used as any other MIPS
registers through the symbols @code{$x0}, @code{$x1}, and so on. They
have a general purpose and are not considered as caller save nor
callee save registers.
@item --prg-display
Display the read program.
@item --prg-solve
Resolve jump offsets and check bounds of immediates.
@item --check-callee-save
Warn if a callee save register is not preserved across a call.
@item --execute
Execute the program on virtual machine.
@item --trace-exec
Trace the execution.
