Yeah it was surprisingly involved! and not at all straightforward as many of the bits and information had bitrotted out of existance.

Good luck with your ST compiling adventure!

The ST only had 4 MB max. RAM, and, as no PMMU was in there, no (UNIX-like) paging.

You can have 10 MB binaries with GEMDOS on the ST, I’m quite sure, although I never tried. Newer releases of RAM extensions can give you 14.5 MB of usable RAM in the ST, of which 10.5 MB are contiguous (“ALT-RAM”).

As the ST predates GCC by 2-3 years, I’m sure that wasn’t on their priority list. It wasn’t designed as a workstation killer.

0.9MB is absolutely tiny. Even back then if you’d ever used GCC or Emacs.

For a 24bit address space having less than 12MB available is a damned shame.

What do you mean with “Atari […] only have tiny areas for programs”? I know of 0.9 MB binaries for the ST …

It was some shell incompatibility from what I recall.

The Atari and x68000 despite having a 24bit address bus only have tiny areas for programs… As much shit as the pc gets for the 640k thing, at least the 286 maps 15 megabytes of linear memory (and its mmu can map 1GB!!!) just as the 386 boards of the era comfortably do 64MB/4 Gb.

Even the SUN-2 only maps 4MB of RAM, in the same 24bjt address space

I touched on gcc 0.9 a while ago. Although you are right in that it supports VAX and 68020. I’m not sure if it’ll force down to 68000 only, and I suspect it may work fine with the assembler from the later versions.

I guess for me it was running down the ancient original stuff I could fine, not so much trying to redo/retrofit it myself from the older stuff.

But Im sure it’s entirely possible.

Sorry if I’m being a bit dense, but: I found what appears to be the source code to gcc 0.9 from 1987. I have no idea if this is helpful 6 months after the fact:

I just discovered your blog and have been enjoying reading stuff!

It’d been ‘opened’ last year but no source. So it’s finally happened. In that time WineVDM has made incredible strides, and at this point I can’t see anything else even coming close to it.
