Use the resulting pcom executable to compile your own Pascal program, which produces a P-Code file (often named prr ).
Written in Pascal, this program translates Pascal source code into P-Code. PASCAL Implementation: P4 Compiler Compiler and...
The compiler is the fourth iteration of the Pascal-P system developed at ETH Zurich. It is a portable "compiler-compiler" implementation kit designed to aid in the bootstrapping of Pascal compilers on new machine architectures by producing an intermediate code known as P-Code . Core Components of the P4 System The system typically consists of two main programs: Use the resulting pcom executable to compile your
By targeting an abstract "P-Machine," the compiler remains machine-independent. To port Pascal to a new system, one only needs to write a P-Code interpreter or a P-Code-to-native-code translator for that specific hardware. Also written in Pascal, it acts as a
Also written in Pascal, it acts as a virtual machine that assembles and executes the P-Code output. Implementation and Bootstrapping Process
The definitive guide to this system is Pascal Implementation: The P4 Compiler and Interpreter by Steven Pemberton and Martin Daniels. It provides the complete, documented source code for both the compiler and interpreter.
Compile pcom.p and pint.p using an existing Pascal compiler.
