Hi!
Enabling cobol explicitly (at least unconditionally) in gcc_release has the
disadvantage that the script no longer works for GCC <= 14, I think it would
be better to keep it working for all still supported release branches.
And as mentioned in the PR, we still don't generate the
--enable-generated-files-in-srcdir extras/infos/man pages for languages
not actually enabled.
Using --enable-languages=all would mean gcc_release takes far longer and
more importantly, various FEs have extra dependencies, Ada requires a
working Ada compiler (furthermore not newer than the gcc release, so if
I run this on a system with say GCC 15 installed, even when I have Ada
installed, I won't be able to gcc_release GCC 14 or 13 etc.), D working D
compiler, Go takes a long time to build libgo.
So, the following patch instead takes similar approach to what
make regenerate-opt-urls
takes, it generates stuff even for non-enabled languages.
For most languages it works just fine and is a matter of say for cobol
make cobol.srcextra cobol.srcinfo cobol.srcman
The only problem is Modula 2, which has some messed up dependencies and
when the FE is not enabled, this will try to build the whole FE as well and
fail. I think it would be useful to fix that but at least before that is
fixed on the trunk and all release branches, the following patch just
conditionally (so that it works even for GCC 12 which doesn't have Modula 2)
enables also m2.
And lastly, libffi seems to be only enabled for Go (and maybe D), I'd prefer
not to enable those languages for the reasons stated above, so if we really
need libffi.info in release tarballs (despite libffi being used only as
implementation detail and not installed), the patch just generates it by
hand.
Tested on x86_64-linux, ok for trunk?

* gcc_release: Use --enable-languages=c,c++,lto and if m2 is available,
with,m2 appended to that. Check for all possible languages and run
make $lang.srcextra $lang.srcinfo $lang.srcman for those. Add
libffi/doc/libffi.info.
