+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
+because it'd make behavior across OS's inconsistent:
+ https://gcc.gnu.org/ml/gcc-patches/2003-07/msg02144.html

+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
+if target headers had sys/sdt.h at ./configure time.
+
+After the change explicitly ask to enable or disable

+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.

+Subject: [PATCH] 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.

+In --enable-default-pie mode compiler should switch from
+using crtend.o to crtendS.o. On sparc it is especially visible
+because crtend.o contains PIC-unfriendly code.
