With the new COBOL support merged into the source of the upcoming GCC 15
release, I have a question around GCC's policy for supporting different
architectures. In short, is the COBOL support initally only targeting
x86 and ARM, or by the time GCC 15 releases should it support all
architectures that it builds for?
I built from the current git master branch on a ppc64le Linux box, with
--enable-languages=c,c++,cobol, and everything built successfully and
produced a gcobol binary. But when using gcobol, it fails with an ICE:
[bug details elided]
I saw somewhere when I was looking at the commits that merged the COBOL
work in that it was only tested on x86 and ARM so far.
See https://gcc.gnu.org/PR119308
Ah, yes, thank you, that's the same behavior.
I searched for bugs when I first hit this earlier this month, but
haven't gotten around to following up until today. Good to see folks are
already jumping on it!
The original stance of the COBOL maintainers was that they're only
really interested in arm64 + x86_64, at least at first(?).
I think we've succeeded in somewhat changing their mind, or at least in
convincing them to accept changes that make porting to other targets
easier (some of this is free while porting to GCC conventions and so on).
That's good -- given the broad set of platforms GCC is used on, adding a
language such as COBOL for only x86_64 and arm64 seems like it wouldn't
be quite ready for merging into a release yet. (I know...I need to be
dragged kicking and screaming into the Real World where x86_64 and arm64
covers the vast majority of what people care about these days.)
Thank you,
Matthew
