A new newlib version has been realized yesterday: newlib-4.3.0 (yearly snapshot)
https://sourceware.org/pipermail/newlib/2023/020141.html
https://sourceware.org/ftp/newlib/index.html → 2023-01-20: newlib-4.3.0.20230120.tar.gz (8.8 MB)

For both nvptx and GCN, the new version is recommended - mostly because of upcoming changes
and not because GCC mainline already needs them currently. But soon it will, hence:

The attached patch bumps the minimal version instead of keeping the old version and only
recommending the newer one.

Comments? Suggestions? – If there are none, I intent to commit the patch as obvious.

PS: For AMDGCN, the newlib uses (if available) some new builtins: one provided by GCC 13
but having the currently same value as the hard coded registers that get used if the builtin
s not available - to permit a change to non-private stack variables (required for reverse offload;
will require recompilation of newlib).
And to support vectorized math functions. (The gcn builtins still have to be added to GCC 13;
if the builtins aren't available, newlib won't use them - hence, also will later require a
rebuild with the newer newlib).

For nvptx, newlib added some features to permit building a non-minimal version of libgfortran,
which also permits I/O. The libgfortran changes have been approved but the GCC nvptx patches
still have to be reviewed (and would also require a pending nvptx-tools pull request).

BTW: The gcn vect math and the nvptx changes went into newlib in the last few days. Thus, if
you have use the 'git' version it won't have the changes, unless you updated at least yesterday.
