MIPS Pascal Compiler

A Pascal Compiler for the MIPS Architecture. Written for Unix in C++, using lex/yacc for parsing and Perl for unit tests.

Requirements

• Unix Environment
• GCC/G++
• SPIM sudo apt-get install spim

Usage

// COMMAND LINE OPTIONS
warnings: -w
optimization:	-O0 / -O1

// COMPILING
make first                                            (prepare folder structure)
make -B                                               (force compiles linker)
make                                                  (compile the program)

// PROGRAM USAGE					
perl ./tests/dotests_spim                             (run full mips test stack)
./comp -w -O1 <./examples/fib.p0 && spim load out.s   (generate and run fibonacci)
./comp -w -O1 <./examples/fact.p0 && spim load out.s  (generate and run factorial)
./comp -w -O1 <./examples/exp.p0 && spim load out.s   (generate and run exponent)

Output MIPS assembly file is written to out.s

// EXAMPLES
The examples allow user input during run time:
fib.p0: one integer               -> output fib(n)
fact.p0: one integer              -> output fact(n)
exp.p0: one float, one integer    -> output x^n
