[PATCH 0/7] gcc: Upgrade GCC to 16.1 release

[Hemanth.KumarMD]

From: Hemanth Kumar M D <Hemanth.KumarMD@windriver.com>

This patch series upgrades GCC to 16.1 and includes the required
runtime and compatibility fixes identified during testing in OE-Core.

The series also includes fixes for packages failing to build with
GCC 16, updates for libatomic runtime handling, and packaging
changes for newly generated libatomic_asneeded files.

Summary of patches:

- Patch 01: Backport piglit fix for building with GCC 16.
- Patch 02: Backport rxvt-unicode fix for building with GCC 16.
- Patch 03: Disable automatic libatomic linking in glibc.
- Patch 04: Upgrade GCC to 16.1 release.
- Patch 05: Disable automatic libatomic linking during gcc-runtime build.
- Patch 06: Package new libatomic_asneeded runtime files.
- Patch 07: Avoid passing MULTIBUILDTOP to libatomic in OE builds.

[PATCH 1/7] piglit:backport a fix for building with gcc-16

[Hemanth.KumarMD]

From: Hemanth Kumar M D <Hemanth.KumarMD@windriver.com>

Avoid conflict with C++20 std::lerp from <cmath>, which
causes redefinition and ambiguous call errors with newer
toolchains.

Upstream-Status: Backport [https://gitlab.freedesktop.org/mesa/piglit/-/commit/ec0fc2fef0755b1595c3799ab25129174a4b2007]

[PATCH 3/7] glibc: disable automatic libatomic linking

[Hemanth.KumarMD]

From: Hemanth Kumar M D <Hemanth.KumarMD@windriver.com>

GCC 16 introduced -flink-libatomic which automatically injects
-latomic_asneeded into link commands via LINK_LIBATOMIC_SPEC. When glibc
is built with a GCC 16 cross-compiler, the compiler would attempt
to link against libatomic which does not exist yet at this stage.
(libatomic is built later as part of gcc-runtime)

Link: https://github.com/gcc-mirror/gcc/commit/e63cf4b130b86dd7dde1bf499d3d40faca10ea2e

[PATCH 4/7] gcc: Upgrade GCC to 16.1 release

[Hemanth.KumarMD]

From: Hemanth Kumar M D <Hemanth.KumarMD@windriver.com>

Notable changes in GCC 16 include:
- Improved C23/C++23 support and initial C++26 features
- Enhanced diagnostics and static analyzer improvements
- Optimizer and code generation enhancements
- Target-specific updates for AArch64, RISC-V, x86, and others
- Runtime library updates (libstdc++, libatomic, libgomp, libsanitizer)
- Multiple bug fixes and performance improvements

* Rebased existing OE-Core patches for GCC 16.1 and dropped
patches merged upstream.

[PATCH 5/7] gcc-runtime: disable automatic libatomic linking during build

[Hemanth.KumarMD]

From: Hemanth Kumar M D <Hemanth.KumarMD@windriver.com>

GCC 16 introduced -flink-libatomic which automatically injects
-latomic_asneeded into link commands via LINK_LIBATOMIC_SPEC.
During gcc-runtime do_compile, OE uses a pre-built GCC 16
cross-compiler to build target runtime libraries before libatomic
itself is ready.

[PATCH 6/7] gcc-runtime: package new libatomic_asneeded files

[Hemanth.KumarMD]

From: Hemanth Kumar M D <Hemanth.KumarMD@windriver.com>

GCC 16 generates libatomic_asneeded.so and libatomic_asneeded.a
during the build as part of the fix for unnecessary DT_NEEDED
entries on libatomic in GCC runtime libraries (PR libstdc++/123396).
Add them to avoid unpackaged files QA errors.

[PATCH 7/7] gcc-runtime: avoid passing MULTIBUILDTOP to libatomic

[Hemanth.KumarMD]

From: Hemanth Kumar M D <Hemanth.KumarMD@windriver.com>

libatomic constructs gcc_objdir using `pwd` and assumes
MULTIBUILDTOP is relative. Passing an absolute MULTIBUILDTOP
from OE results in malformed paths during libtool install
operations in both compile and install stages.

Avoid passing MULTIBUILDTOP for libatomic and use the upstream
default handling instead.

Hi Hemanth,

Thanks for the upgrade.

We can see various failures on the autobuilder:

gn build failure with musl:

Hi Mathieu,

Thanks for the review and testing.
Here is the current status:
- gn build failure with musl: fixed.
- libgfortran QA failure (libcaf_shmem.a): fixed.
- elfutils ptest failures (run-strip-nothing.sh, run-strip-g.sh): fixed.
- libc-test static test failures (musl only): fixed.

We also ran into a GCC 16 ICE during testing (extract_insn during IRA
pass with UNSPEC_IEEE_MAX on i386 with -ffloat-store) and have reported
it upstream:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=125308

Still looking into the remaining failures. Will keep this thread
updated and send v2 once everything is sorted.

Thanks,
Hemanth Kumar M D
