MiniCompiler

Compiler for the Mini Language

Build Instructions

The program comes packaged with a Makefile. To build the compiler just run make. This will compile all of the java classes into the bin folder.

Running the Compiler

There is an included file run.sh which will properly call the java program with the correct classpath. You pass it the path to the .mini source file. Assembly files are saved to the asm folder. ILOC files are saved to the iloc folder. Control Flow Graphs for each compiled functions are saved as a .dot file in the dot folder.

Usage: ./run.sh [-no_out] [option...] sourceFile [option...]

• -no_out : Hides debug developer messages during the compile process
• dumpIL : Saves the ILOC instructions to a file
• -keepDead : Doesn't remove "dead" instructions
• -noCopyProp : Doesn't perform copy propogation
• -preserveConst : Loads all constants into registers, rather than performing constant folding and constant propogation
• -spillAll : Spills all values to memory

This will produce a .s file in the asm folder that you can then use gcc to compile into an executable.

Currently the only tested options for the benchmarks are to keep all of the optimizations enabled.

Testing Benchmarks

There is an included file that will test the benchmarks.

Usage: ./testBenchmarks.sh [option]

• -q : Run all the benchmarks with the -no_out options
• -s : Run with no_out option and also hide all compiler warnings
• -t : Time the run time of the compiler generate code, as well as the run time for gcc optimizations levels -O0 through -O3

All benchmarks are currently passing.
