This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "gcc-wwwdocs".
The branch, master has been updated via 794555052d5c1d9a92298aba1fc4b645042946dd (commit) from c5e08294215518f00e9762cebe3d6f46f1f00526 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit 794555052d5c1d9a92298aba1fc4b645042946dd Author: Tobias Burnus <tbur...@baylibre.com> Date: Tue Apr 16 09:57:57 2024 +0200 gcc-14/changes.html + projects/gomp/: Fix OpenMP/OpenACC changes section/anchor In earlier release notes, OpenMP and OpenACC changes were under "New Languages and Language specific improvements", either directly under that section as in 4.2, 4.4, 4.7, 4.9, 5, 6 (+ c-family + Fortran), 10, 11, and 12 or under a subsection in 4.5 (Fortran), 4.8 (C++), 7 (Fortran), 9 (c-family). In gcc-13, the OpenMP and OpenACC ended up by chance under "General Improvements", which gcc-14 replicated. This commit does not touch gcc-13 to avoid breaking links, but it corrects the anchor used in the links to GCC 13 in projects/gomp/. However, for GCC 14, it moves the OpenMP/OpenACC changes to the language section. diff --git a/htdocs/gcc-14/changes.html b/htdocs/gcc-14/changes.html index b4c602a5..6035ae37 100644 --- a/htdocs/gcc-14/changes.html +++ b/htdocs/gcc-14/changes.html @@ -59,6 +59,75 @@ a work-in-progress.</p> <!-- .................................................................. --> <h2 id="general">General Improvements</h2> +<ul> + <li>For offload-device code generated via OpenMP and OpenACC, the math + and the Fortran runtime libraries will now automatically be linked, + when the user or compiler links them on the host side.
