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

+it).
+
+To satisfy those people who may not want -mieee forced on them all the time,
+we also provide -mno-ieee.
+
+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
+behaving the same across arches under Linux.

+Subject: [PATCH] driver: Also prune joined switches with negation
+
+When -march=native is passed to host_detect_local_cpu to the backend,
+it overrides all command lines after it. That means
+
+$ gcc -march=native -march=skylake-avx512
+
+is the treated as
+
+$ gcc -march=skylake-avx512 -march=native
+
+Prune joined switches with Negative and RejectNegative to allow
+-march=skylake-avx512 to override previous -march=native on command-line.
+

+
+ PR driver/69471
+ * opts-common.c (prune_options): Also prune joined switches
+ with Negative and RejectNegative.
+ * config/i386/i386.opt (march=): Add Negative(march=).

+Subject: [PATCH] libsanitizer: Remove cyclades inclusion in sanitizer
+
+The Linux kernel has removed the interface to cyclades from
+the latest kernel headers[1] due to them being orphaned for the
+past 13 years.
+
+libsanitizer uses this header when compiling against glibc, but
+glibcs itself doesn't seem to have any references to cyclades.
+
+Further more it seems that the driver is broken in the kernel and
+the firmware doesn't seem to be available anymore.
+
+As such since this is breaking the build of libsanitizer (and so the
+GCC bootstrap[2]) I propose to remove this.

+Ensure that msgfmt doesn't encounter problems during gcc bootstrapping.
+
+Solves error messages like the following:
+
+msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
+
+The libgcc_s.so used during build doesn't satisfy the needs of the
+libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
+is used as a stand-alone application here, and what library it uses
+behind the scenes is of no concern to the gcc build process.
+Therefore, simply invoking it "as usual", i.e. without any special
+library path, will make it work as expected here.
