Detailed Description

Piece of intermediate representation resource.

A Tiger program may include strings. These strings are not left as is in the body of the IR, rather we associate a label to them, and use that label instead.

We store the string elsewhere, to be output in a format which is assembly language dependent. DataFrag are used for this. It is under the responsibility of translate:: to keep all the fragments.

The same thing happens with function declarations: they will be output elsewhere. This is what ProcFrag is used for.
