How is the fork of gcc modified here?

[IoIxD]

I'm wondering what steps it would take to update the gcc in the repo or even swap it out for a different compiler that already supports m68k/ppc32. It seems like most of the work is done by Elf2Mac, and then the standard library port is seperate... which makes me wonder if a fork of gcc even needs to be in the repo in the first place.

The gcc fork contains some patches that are necessary to build classic mac software (see the README). Most of these are more relevant for 68K, but some apply to PPC.

When I update to a new gcc version, my process is as follows:

• I import the upstream versions of gcc, binutils & newlib into the upstream brach
• I create a new branch from master and merge upstream into it
• I spend a day or two resolving conflicts
• I look at diffs between old upstream & master to double-check whether everything important made it to the new version
• Some testing and some fixing of regressions
• merge to master

I don't have the capacity to do that for every gcc release, but so far I've managed to do it 'occasionally, before the included gcc gets too old'.
