Now recommended is 4.3.0 which was just released on 2023-01-20. While currently the old versions would work fine, upcoming GCC changes depend on a newer newlib. Thus, the minimal version is bumped instead of just recommending the new version. For GCN, the bump is in preparation for permitting non-threadlocal stack variables and vectorized math functions - both scheduled for GCC 13 and added to newlib in 4.3.0. For nvptx, this includes an emulated clock (commit 6bb96d13a), a calloc fix (5fca4e0f1) and changes to permit libgfortran to be compiled with I/O support instead of only in minimal mode. (Patch approved for GCC 13 but pending on a nvtpx patch, which for which review is pending.) gcc/ChangeLog: * doc/install.texi (amdgcn, nvptx): Require newlib 4.3.0.
