MyCompiler

It compiles a source file written with the rules stated in the file Informal Reference Manual for X.pdf to produce MIPS assembly.

How To Run

By running script.sh, it will use myLexer.l and myParser.y to generate the executable generatorTC (target code generator) and compile all the testcases (files named sample*.in) in the directory TestCases.

To compile your own input source file (suppose it is filename.in), type

./generatorTC filename.in

then it will produce the output file (named filename.out.s) containing MIPS assembly. Run the file with spim simulator to check the output. For this do the following:

1. Run spim
2. In spim console, type load "filename.out.s"
3. Type run

Note

• All the source files like sample*.in in the directory TestCases are written according to the manual Informal Reference Manual for X.pdf.

• Subprogram (function) can take multiple values as arguments but return two values at most

• Pointers or Arrays are NOT implemented

• :=print:=arg1,arg2,arg3,... will show output as stdout. Besides the keyword newline given as an argument will yield a newline in stdout.

• arg:=Input_Integer:= will take integer from stdin.
