Use the resulting pcom executable to compile your own Pascal program, which produces a P-Code file (often named prr ).
To use the P4 system for compiler implementation, you follow these steps:
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. PASCAL Implementation: P4 Compiler Compiler and...
Modern versions and fixes (such as ISO 7185 compliance) are available on platforms like GitHub and Hans Otten's Pascal site . Technical Characteristics
Also written in Pascal, it acts as a virtual machine that assembles and executes the P-Code output. Implementation and Bootstrapping Process Use the resulting pcom executable to compile your
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.
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: Modern versions and fixes (such as ISO 7185
Compile pcom.p and pint.p using an existing Pascal compiler.
