From: Tobias Burnus <burnus@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r13-5286] install.texi: Bump newlib version for nvptx + gcn Date: Mon, 23 Jan 2023 08:33:03 +0000 (GMT) [thread overview] Message-ID: <20230123083303.02C353858D32@sourceware.org> (raw) https://gcc.gnu.org/g:e94e9944f59b00de455bb719fd0c5281c5509be6 commit r13-5286-ge94e9944f59b00de455bb719fd0c5281c5509be6 Author: Tobias Burnus <tobias@codesourcery.com> Date: Mon Jan 23 09:31:11 2023 +0100 install.texi: Bump newlib version for nvptx + gcn Before, newlib 3.2 was required for amdgcn and 3.1 for nvptx. 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.
