Tree Parsing

Type-`.tp'-files specify tree parsers. Tree parsers can be used to transform, interpret and print tree-structured data. They are particularly useful for problems in which the action at a node depends strongly on the context in which that node appears. Code selection is a common example of this kind of problem: The code selected for an operation is largely determined by that operation's context.

Specifications written in the TP language are analyzed for consistency and then compiled into specifications for the BURG processor (Fraser, C. W., R. R. Henry and T. A. Proebsting, "BURG -- Fast Optimal Instruction Selection and Tree Parsing", SIGPLAN Notices 27, 4 (April, 1992) 68-76). Eli will now also accept raw BURG specifications (file type `.burg'), but we recommend that TP specifications be used instead because they are easier to write and understand.

For a detailed treatment of tree parsers, see Top of Tree Parsing.
