+Set the default behavior on alpha to use -mieee since the large majority of

+To satisfy those people who may not want -mieee forced on them all the time,

+
+Patch by Mike Frysinger <vapier@gentoo.org>
+
+Note: upstream doesn't want to take this due to long standing behavior, and

+
+This makes sense for upstream, but Gentoo is more concerned about packages

+Subject: [PATCH] gcc/config.gcc: sh-*: Disable sysroot-suffix (PR42947)
+
+sh-* is a multilib target. It is also one of 2 sysroot-prefix targets.
+Unfortunately two options do not mix well. Attempt to use default
+multilib flavour always prepends sysroot-prefix.

+
+Before the change systemtap probes were enabled

+Subject: [PATCH] gcc/expmed.h: increase cache size from 10^3 to 10^6
+
+Without this patch is takes dev-libs/xxhash 1-2 hours
+to compile. With this patch - TODO measurements.
+
+It workarounds deficiency of synth_mult() which evics
+cache entries as it calculates optimal multiplication
+algorithm. xxhash is especially hevyweight as it's a
+64-bit multiplication of large prime constants.

11.0.0: Disable -fdelayed-branch by default.

From https://gcc.gnu.org/PR96015 / https://bugs.gentoo.org/729570.
delayed branches are known to generate invalid code around
__builtin_unreachable(); and mis-compiles python.

Use blunt hammer and disable delayed slots until we have better fix.

11.0.0: drop 16_all_libgfortran-Werror.patch patch

Gentoo does not ship patch with poison system directories anymore.
Upstream did not accept -Werror removal. Let's drop downstream patch.

We can always reintroduce it back if needed.
