+Ensure that msgfmt doesn't encounter problems during gcc bootstrapping.

+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] libgo: use POSIX shell arithmetic expansion
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+Avoid bash-specific ((expression)) syntax. As the bash syntax
+converts a non-zero value to a zero status (and a zero value to a 1
+status), and POSIX arithmetic expansion does not, we have to negate
+the result.
+
+Based on patch by Sören Tempel.

+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] c++: equivalence of non-dependent calls [PR107461]
+
+After r13-5684-g59e0376f607805 the (pruned) callee of a non-dependent
+CALL_EXPR is a bare FUNCTION_DECL rather than ADDR_EXPR of FUNCTION_DECL.
+This innocent change revealed that cp_tree_equal doesn't first check
+dependence of a CALL_EXPR before treating a FUNCTION_DECL callee as a
+dependent name, which leads to us incorrectly accepting the first two
+testcases below and rejecting the third:
+
+ * In the first testcase, cp_tree_equal incorrectly returns true for
+ the two non-dependent CALL_EXPRs f(0) and f(0) (whose CALL_EXPR_FN
+ are different FUNCTION_DECLs) which causes us to treat #2 as a
+ redeclaration of #1.
+
+ * Same issue in the second testcase, for f<int*>() and f<char>().
+
+ * In the third testcase, cp_tree_equal incorrectly returns true for
+ f<int>() and f<void(*)(int)>() which causes us to conflate the two
+ dependent specializations A<decltype(f<int>()(U()))> and
+ A<decltype(f<void(*)(int)>()(U()))>.
+
+This patch fixes this by making called_fns_equal treat two callees as
+dependent names only if the overall CALL_EXPRs are dependent, via a new
+convenience function call_expr_dependent_name that is like dependent_name
+but also checks dependence of the overall CALL_EXPR.
+
+ PR c++/107461
+
+gcc/cp/ChangeLog:
+
+ * cp-tree.h (call_expr_dependent_name): Declare.
+ * pt.cc (iterative_hash_template_arg) <case CALL_EXPR>: Use
+ call_expr_dependent_name instead of dependent_name.
+ * tree.cc (call_expr_dependent_name): Define.
+ (called_fns_equal): Adjust to take two CALL_EXPRs instead of
+ CALL_EXPR_FNs thereof. Use call_expr_dependent_name instead
+ of dependent_name.
+ (cp_tree_equal) <case CALL_EXPR>: Adjust call to called_fns_equal.

12.2.0: drop 76_all_all_PR107461_cxx_equivalence_non_dependent_calls.patch (upstream)
Drop now that we created 12.x and 13.x patchsets with this in, as it's
in the git repo now and keeping it in gcc-patches.git will break live
ebuilds.
Will be in next snapshot too as a result.

-Subject: [PATCH] c++: equivalence of non-dependent calls [PR107461]
-
-After r13-5684-g59e0376f607805 the (pruned) callee of a non-dependent
-CALL_EXPR is a bare FUNCTION_DECL rather than ADDR_EXPR of FUNCTION_DECL.
-This innocent change revealed that cp_tree_equal doesn't first check
-dependence of a CALL_EXPR before treating a FUNCTION_DECL callee as a
-dependent name, which leads to us incorrectly accepting the first two
-testcases below and rejecting the third:
-
- * In the first testcase, cp_tree_equal incorrectly returns true for
- the two non-dependent CALL_EXPRs f(0) and f(0) (whose CALL_EXPR_FN
- are different FUNCTION_DECLs) which causes us to treat #2 as a
- redeclaration of #1.
-
- * Same issue in the second testcase, for f<int*>() and f<char>().
-
- * In the third testcase, cp_tree_equal incorrectly returns true for
- f<int>() and f<void(*)(int)>() which causes us to conflate the two
- dependent specializations A<decltype(f<int>()(U()))> and
- A<decltype(f<void(*)(int)>()(U()))>.
-
-This patch fixes this by making called_fns_equal treat two callees as
-dependent names only if the overall CALL_EXPRs are dependent, via a new
-convenience function call_expr_dependent_name that is like dependent_name
-but also checks dependence of the overall CALL_EXPR.
-
- PR c++/107461
-
-gcc/cp/ChangeLog:
-
- * cp-tree.h (call_expr_dependent_name): Declare.
- * pt.cc (iterative_hash_template_arg) <case CALL_EXPR>: Use
- call_expr_dependent_name instead of dependent_name.
- * tree.cc (call_expr_dependent_name): Define.
- (called_fns_equal): Adjust to take two CALL_EXPRs instead of
- CALL_EXPR_FNs thereof. Use call_expr_dependent_name instead
- of dependent_name.
- (cp_tree_equal) <case CALL_EXPR>: Adjust call to called_fns_equal.
-
-gcc/testsuite/ChangeLog:
-
- * g++.dg/cpp0x/overload5.C: New test.
- * g++.dg/cpp0x/overload5a.C: New test.
- * g++.dg/cpp0x/overload6.C: New test.

negatives where the sanitizer misses something.
