+# DP: libgcc backports from the trunk:
+# DP: - Always define USE_PT_GNU_EH_FRAME in crtstuff.c for glibc.
+# DP: - Build static libgcc with hidden visibility even with --disable-shared.

+libgcc/
+2012-08-19  Joseph Myers  <joseph@codesourcery.com>
+
+	* crtstuff.c (USE_PT_GNU_EH_FRAME): Define for systems using glibc
+	even if inhibit_libc.
+
+2012-08-22  Joseph Myers  <joseph@codesourcery.com>
+
+	* Makefile.in (vis_hide, gen-hide-list): Do not make definitions
+	depend on --enable-shared.
+	($(lib1asmfuncs-o)): Use %.vis files independent of
+	--enable-shared.
+	* static-object.mk ($(base)$(objext), $(base).vis)
+	($(base)_s$(objext)): Use same rules for visibility handling as in
+	shared-object.mk.
