GCC 10.4
60 bug reports were fixed.
Target Specific Changes
x86-64
* The x86-64 ABI of passing and returning structures with a 64-bit
integer vector changed in GCC 10.1 when MMX is disabled. Disabling
MMX no longer changes how they are passed nor returned. This ABI
change is now diagnosed with -Wpsabi.
This relates to the case when GCC is built using clang host CC. In that
case the runtime libraries are not built with RELRO for some reason.
for the gcc*-libs/ packages, mark them as RELRO_SUPPORTED=no unconditionally.
RELRO status depends on how the parent gcc package was built so we don't
need nor care about the RELRO status here.

Target Specific Changes
AArch64
A bug with the Random Number intrinsics in the arm_acle.h header
that resulted in an incorrect status result being returned has
been fixed.
GCC now supports the Fujitsu A64FX. The associated -mcpu and
-mtune options are -mcpu=a64fx and -mtune=a64fx respectively.
In particular, -mcpu=a64fx generates code for Armv8.2-A with
SVE and tunes the code for the A64FX. This includes tuning the
SVE code, although by default the code is still length-agnostic
and so works for all SVE implementations. Adding -msve-vector-bits=512
makes the code specific to 512-bit SVE.
While here point out that the aarch64 equivalent patch was sent upstream.
Bump PKGREVISION. fix gcc*-libs PKGREVISION accordingly.

The GNU Compiler Collection (GCC) includes front ends for C, C++, Objective-C,
Fortran, and Go, as well as libraries for these languages (libstdc++,
libgfortran, ...).
This packages provides GCC support libraries in a specific location and allows
packages to depend on just the libraries rather than having to pull in the full
GCC package.
