Hi,

I'm happy to announce that I've just released OSELAS.Toolchain-2024.11.1.

This is a bugfix only release. There are no major update. The relevant
changes are:

 - gcc was updated to the 14-20250308 snapshot release.
 - glibc was updated to 2.40-105-gd8e834236983 in the stable branch.
 - All patches from the binutils stable branches that seemed relevant
   have been cherry-picked.
 - llvm, clang and lld were updated to 19.1.7, the latest 19.1 stable
   release.
 - rustc now actually uses the shared llvm. It accidentally built its own
   llvm before. As a result there where some build failures, because
   rust-lld did not support zstd compression in object files. The shared
   llvm is built with zstd support, so using that fixes this problem.

Download the release here:
https://public.pengutronix.de/oselas/toolchain/

Debian / Ubuntu Packages will be available at
http://debian.pengutronix.de/

For the binary packages, the plan is the same as for the corresponding
major release. They should show up over the next few days.

Enjoy,
Michael Olbrich

I'm guessing that this won't have the 64-bit time_t support in 32-bit 
libstdc++ since it's a bugfix only release. Is that correct?

Thanks.

Correct. And to be honest, I'm not sure how I should handle this. I've been
digging some more and there is a lot of code like this:

#ifdef _GLIBCXX_USE_CLOCK_GETTIME_SYSCALL
      syscall(SYS_clock_gettime, CLOCK_REALTIME, &tp);
#else
      clock_gettime(CLOCK_REALTIME, &tp);
#endif

And the problem with that is, that -D_TIME_BITS=64 only works correctly if
clock_gettime() is used and not the syscall directly. And I'm not sure how
to guarantee that.
And so far, I've not really found any indication that gcc upstream is
actually working on that in any way.

So I don't know what I will do for the next major release. Just building
with -D_TIME_BITS=64 for the official toolchains is not something that I'm
comfortable with right now.
Maybe an option to enable it and keep it disabled by default? That way, you
could at least build the toolchain with it in a defined way.

Michael
