work for benifit of university students who are interested in working of

benifit form it.



==== Description: ====
jlang Complier

jlang is a small and easy to learn language designed by Jatin Bhateja.
It chiefly does mathematical operations on data variables.Languge is easy
to unterstand and is basically develoved for educational purpose.

jlang complier is small and tidy complier written by the language designer
translate the source language to machine language. Compiler has a LR(1)
parser constructed using bison. 

Compiler Working

Complier initialy creates an AST for jlang source program.
Once complete AST is constructed then semantic checks are performed
on the tree.Along with semantic checking constant folding optimization is
performed on the AST. Before semantic checking symbol resolving is done so
symbols in AST point to their symbol table entry.

After doing semantic checking AST is translated to intermediate code
this stage CSE , constant/copy propogation optimization ,dead code
elemination  and 
some algebraic optimization is performed on the iCode.

Finally optimized iCode is converted to MACHINE language by backend.

About the Assembly

Machine language constitutes of simple and self explanatory instruction set.
Assembly is generated in AT&T Format.

==== Other Software Required: ====

==== Other Comments: ====
Project is basically meant for people who want to have a look at the internal
working of compiler quickly.Beneficial for university students.
