# README for the BLISS-M Compiler

This is the source package for the BLISS-M compiler, a portable

cross-compiler for the BLISS programming language.

## What is BLISS?

The BLISS language was developed at Carnegie-Mellon University in the 1970's for systems programming.

It was adopted and used extensively by Digital Equipment Corporation for development of systems

software across their 16-bit, 32-bit, 36-bit, and 64-bit systems.  It is a typeless, block-structured,

language with an extensive lexical processing (macro) facility.  See the

[Wikipedia article on BLISS](http://en.wikipedia.org/wiki/BLISS) for more information about the language.

## Current Status

Work in progress.   The front-end is mostly complete, with a fully

functioning parser and macro facility.  Back-end support is currently

limited to LLVM and x86 CPUs (32- or 64-bit), with a limited amount

of machine-specific support.

## Prerequisites

* Recent-vintage C compiler

* Recent version of LLVM (one that has support for opaque pointers)

* CMake 3.13 or later, or a recent version of autotools

Recent development and testing has been on Ubuntu 24.04 with

gcc 13 and LLVM 14, 17, and 18.

## Building the compiler

First, clone [the repository](https://github.com/madisongh/blissc.git).

### Using Autotools

1. cd to the top-level source directory and run `autoreconf -i`.

2. If you want to build outside the source tree, cd to your

   build directory.

3. Run the `configure` script that was generated in step 2.  If

   `llvm-config` is not in your PATH, use the `--with-llvm-config`

   option on `configure` to specify its location.

4. Run `make` to build the compiler.

5. Run `make check` to test the built compiler.

### Using CMake

1. Create a directory for the build.

2. Run `cmake ` to generate the build files.

   CMake will attempt to locate a usable copy of LLVM automatically,

   but you can specify -DLLVM_CONFIG= to force

   it to use a particular installation of LLVM.

3. Run `make` to build the compiler.

Running the compiler

--------------------

The build will produce a program called **blissc** in your build

directory.  Run `./blissc --help` for a description of the arguments

and options.
