[-- Attachment #1: Type: text/plain, Size: 531 bytes --]

There is a new pull request by leahneukirchen against master on the void-packages repository

https://github.com/leahneukirchen/void-packages gcc-atomics
https://github.com/void-linux/void-packages/pull/36001

gcc: add --enable-autolink-libatomic.
First stab at #35992.

The hack with the empty libatomics.a is pretty ugly, but required for a cross-build, as we cannot build libatomic in the bootstrap gcc due to autoconf limitations. :(

A patch file from https://github.com/void-linux/void-packages/pull/36001.patch is attached

Subject: [PATCH 1/4] gcc: depend on libatomic-devel.

As explained in #35992, gcc generates code that needs libatomic
in some cases, so include it by default.

Subject: [PATCH 2/4] gcc: use --enable-autolink-libatomic for platforms that
 often need atomics.

As explained in #35992, gcc often generates code that needs libatomic
on these platforms, so link to libatomic by default (as-needed).

+Subject: [PATCH] configure: fix detection of atomic builtins in libatomic
+ configure script
+
+Alpine's --enable-autolink-libatomic (which is enabled for riscv64 by
+default) causes the libatomic configure script to incorrectly detect
+which builtins are available on riscv64. This then causes incorrect code
+generation for libatomic since it assumes compiler builtins to be
+available which are not actually available on riscv64.
+
+This commit fixes this issue by disabling linking of libatomic configure
+test code entirely, thereby preventing linking against libatomic.
+

Comment:
Smoke tested for armv6hf on a package that now doesn't require explicit `-latomic` anymore, but still links it.

There's a closed pull request on the void-packages repository

gcc: add --enable-autolink-libatomic.
https://github.com/void-linux/void-packages/pull/36001

Description:
First stab at #35992.

The hack with the empty libatomics.a is pretty ugly, but required for a cross-build, as we cannot build libatomic in the bootstrap gcc due to autoconf limitations. :(
