A MIPS compiler for the Tiger language created by Andrew Appel.
This compiler is written in SML (Standard ML of New Jersey) v110.99. Get the latest version here: https://www.smlnj.org/.
SPIM can be used to test the generated MIPS assembly, which can be downloaded here: http://spimsimulator.sourceforge.net/.
The target language of this compiler, Tiger, is a small language with nested functions, record values with implicit pointers, arrays, integer and string variables, and a few simple structured control constructs. A detailed manual can be found in the PDF file tiger.pdf in this repo.
To use the compiler, first type sml in terminal window to start the repl.
Then, type CM.make "sources.cm" to compiler the modules.
Now, assembly for the Tiger language can be generated using the function Main.compile. For example, to compiler the program queens.tig which solves the 8 Queens Problem, simply type Main.compile queens.tig, and an MIPS assembly file queens.s will be generated in the same directory.
- Tiger is a typed language and our compiler does type checking. If there is a typing error, an error message will be generated.
- Our compiler also does bounds checking for array subscriptions. If the index is larger than the size of the array or smaller than 0, the program will instantly exit.
