+
+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.

+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.

+Subject: [PATCH] Fix calling libarchive's tar
+
+https://bugs.gentoo.org/886447
+
+Very similar to 33_all_msgfmt-libstdc++-link.patch, whose description is:
+"""
+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.

+Subject: [PATCH] rtl-optimization/109585 - alias analysis typo
+
+When r10-514-gc6b84edb6110dd2b4fb improved access path analysis
+it introduced a typo that triggers when there's an access to a
+trailing array in the first access path leading to false
+disambiguation.
+
+ PR rtl-optimization/109585
+ * tree-ssa-alias.c (aliasing_component_refs_p): Fix typo.
+
+ * gcc.dg/torture/pr109585.c: New testcase.
+
+(cherry picked from commit 6d4bd27a60447c7505cb4783e675e98a191a8904)
