Description:

ppci 0.5.8

The PPCI (Pure Python Compiler Infrastructure) project is a compiler
written entirely in the Python programming
language. It contains front-ends for various programming languages as
well as machine code generation functionality. With this library you can
generate (working!) machine code using Python (and thus very easy to
explore, extend, etc.)!
The project contains:

Language frontends for C, Python, Pascal, Basic and Brainfuck
Code generation for several architectures: 6500, arm, avr, m68k, microblaze, msp430, openrisc, risc-v, stm8, x86_64, xtensa
Command line utilities, such as ppci-cc, ppci-ld and ppci-opt
WebAssembly, JVM, OCaml support
Support for ELF, EXE, S-record and hexfile formats
An intermediate representation (IR) which can be serialized in json
The project can be used as a library so you can script the compilation process

Installation
Since the compiler is a python package, you can install it with pip:
$ pip install ppci

Usage
An example of commandline usage:
$ cd examples/linux64/hello-make
$ ppci-cc -c -O1 -o hello.o hello.c
...
$ ppci-ld --entry main --layout linux64.ld hello.o -o hello
...
$ ./hello
Hello, World!
API example to compile C code:
>>> import io
>>> from ppci.api import cc, link
>>> source_file = io.StringIO("""
... int printf(char* fmt) { }
...
... void main() {
... printf("Hello world!\n");
... }
... """)
>>> obj = cc(source_file, 'arm')
>>> obj = link([obj])
Example how to assemble some assembly code:
>>> import io
>>> from ppci.api import asm
>>> source_file = io.StringIO("""section code
... pop rbx
... push r10
... mov rdi, 42""")
>>> obj = asm(source_file, 'x86_64')
>>> obj.get_section('code').data
bytearray(b'[ARH\xbf*\x00\x00\x00\x00\x00\x00\x00')
Example of the low level api usage:
>>> from ppci.arch.x86_64 import instructions, registers
>>> i = instructions.Pop(registers.rbx)
>>> i.encode()
b'['

Functionality

Command line utilities:

ppci-cc
ppci-ld
and many more.

Can be used with tools like make or other build tools.

Language support:

C
Pascal
Python
Basic
Brainfuck
C3
(PPCI’s own systems language, intended to address some pitfalls of C)

CPU support:

6500, arm, avr, m68k, microblaze, msp430, openrisc, risc-v, stm8, x86_64, xtensa

Support for:

WebAssembly
JVM
OCaml bytecode
LLVM IR
DWARF debugging format

File formats:

ELF files
COFF PE (EXE) files
hex files
S-record files

Uses well known human-readable and machine-processable formats like JSON and XML as
its tools’ formats.
