-Subject: [PATCH] Preserve structured CUDA output arrays
-
-The multiple-outputs hook now accepts arrays. The old compatibility export
-collapses include and lib into one array element, breaking indirect expansion.
-Keep the array and iterate over each output when propagating to out.

-Subject: [PATCH] lib/x86/cpu_features.h: drop evex512 on gcc-16
-
-gcc-16 `master` branch dropped support for `evex512` as:
-    https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=c052a6f4a1c803cb92147ff98fb91cf3511e0856
-
-As a result libdeflate build started failing as:
-
-    In file included from /build/source/lib/adler32.c:28:
-    /build/source/lib/x86/adler32_template.h:135:12: error: attribute 'target' argument 'no-evex512' is unknown
-      135 | ADD_SUFFIX(reduce_to_32bits)(vec_t v_s1, vec_t v_s2, u32 *s1_p, u32 *s2_p)
-          |            ^~~~~~~~~~~~~~~~
-
-The change adds upper build to `evex512` for `gcc`.
