+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
+behaving the same across arches under Linux.

+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.

+Subject: [PATCH] gcc/configure.ac: add --disable-systemtap switch
+
+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
+for probe support and not rely on automagic dependency
+discovery.

+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] libstdc++-v3: Update VTV vars for libtool link commands
+ [PR99172]
+
+This fixes PR 99172
+
+Currently when GCC is configured with --enable-vtable-verify, the
+libstdc++-v3 Makefiles add "-fvtable-verify=std
+-Wl,-u_vtable_map_vars_start,-u_vtable_map_vars_end" to libtool link
+commands. The "-fvtable-verify=std" piece causes alternate versions of
+libtool (such as slibtool) to fail, unable to find "-lvtv" (GNU
+libtool just removes that piece).
+
+This patch updates the libstdc++-v3 Makefiles to not pass
+"-fvtable-verify=std" to the libtool link commands.

+
+My patch for PR98463 added an assert that tripped on this testcase, because
+we ended up with a U CONSTRUCTOR with an initializer for a, which is not a
+member of U. We need to wrap the a initializer in another CONSTRUCTOR for
+the anonymous union.
+
+For the GCC 10 branch, just remove the assert.

+Subject: [PATCH] c++: tsubst_function_decl and excess arg levels [PR100102]
+
+Here, when instantiating the dependent alias template
+duration::__is_harmonic with args={{T,U},{int}}, we find ourselves
+substituting the function decl _S_gcd. Since we have more arg levels
+than _S_gcd has parm levels, an old special case in tsubst_function_decl
+causes us to unwantedly reduce args to its innermost level, yielding
+args={int}, which leads to a nonsensical substitution into the decl
+context and eventually a crash.
+
+The comment for this special case refers to three examples for which we
+ought to see more arg levels than parm levels here, but none of the
+examples actually demonstrate this. In the first example, when
+defining S<int>::f(U) parms_depth is 2 and args_depth is 1, and
+later when instantiating say S<int>::f<char> both depths are 2. In the
+second example, when substituting the template friend declaration
+parms_depth is 2 and args_depth is 1, and later when instantiating f
+both depths are 1. Finally, the third example is invalid since we can't
+specialize a member template of an unspecialized class template like
+that.
+
+Given that this reduction code seems no longer relevant for its
+documented purpose and that it causes problems as in the PR, this patch
+just removes it. Note that as far as bootstrap/regtest is concerned,
+this code is dead; the below two tests would be the first to reach it.
+

+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.
