Free Pascal Compiler The page contains parts of the Free Pascal compiler source code.

Units

compiler - This unit is the interface of the compiler which can be used by external programs to link in the compiler

symconst - Symbol table constants

symbase - This unit handles the symbol tables

symtype - This unit handles the symbol tables

symsym - Implementation for the symbols types of the symtable

symdef - Symbol table implementation for the definitions

defcmp - Compare definitions and parameter lists

defutils - This unit provides some help routines for type handling

scanner - This unit implements the scanner part and handling of the switches

scandir - This unit implements directive parsing for the scanner

parser - This unit does the parsing process

pbase - Contains some helper routines for the parser

pdecl - Does declaration (but not type) parsing for Free Pascal

pdecobj - Does object types for Free Pascal

pdecsub - Does the parsing of the procedures/functions

pdecvar - Parses variable declarations. Used for var statement and record definitions

pexports - This unit handles the exports parsing

pexpr - Does parsing of expression for Free Pascal

pinline - Generates nodes for routines that need compiler support

pmodules - Handles the parsing and loading of the modules (ppufiles)

pstatmnt - Does the parsing of the statements

psub - Does the parsing and codegeneration at subroutine level

ptconst - Reads typed constants

ptype - Does parsing types for Free Pascal

constexp - This unit implements a Tconstexprint type. This type simulates an integer type that can handle numbers from low(int64) to high(qword) calculations.
