388779 - rewrite config.guess / config.sub in Python

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[(not currently active) Ted Mielczarek]

As part of our configure system rewrite, we're going to rewrite portions of the configure system in Python.  config.guess and config.sub are nice, standalone scripts.  We don't intend to produce a complete port, these scripts support a huge amount of legacy architectures that we've never supported.  We'll support a basic subset, and port maintainers can add support for others.

Attachment: Replace config.guess

This config.guess replacement handles Windows (MSYS/Cygwin), Linux, OS X, and Solaris x86.  I've verified that it produces identical output on all the platforms I have access to.  (Basically everything but Mac PPC, but I poked at the Python library, and I think I got it right there.)

I didn't add a license header to guess.py, I still need to do that.

Attachment: replace config.guess and config.sub

Ok, this replaces both config.guess and config.sub.  The shell scripts are reduced to one-liners calling the python script.  The python script behaves like config.guess if no arguments are given, and config.sub if one argument is given.

replace config.guess and config.sub

The dictionary-keyed-with-strings-or-regexes looks a little odd to me, and I expect that we'll have to abstract that away in the future, but I guess it's ok for now.

We should switch to calling guess.py directly from the configure script ASAP.
