+Subject: [PATCH 16/58] [Patch, microblaze]: Add INIT_PRIORITY support
+
+Added TARGET_ASM_CONSTRUCTOR and TARGET_ASM_DESTRUCTOR macros.
+
+These macros allows users to control the order of initialization
+of objects defined at namespace scope with the init_priority
+attribute by specifying a relative priority, a constant integral
+expression currently bounded between 101 and 65535 inclusive.
+
+Lower numbers indicate a higher priority.
+
+Changelog
+
+2013-11-26  Nagaraju Mekala <nagaraju.mekala@xilinx.com>
+
+ * gcc/config/microblaze/microblaze.c: Add microblaze_asm_constructor,
+   microblaze_asm_destructor. Define TARGET_ASM_CONSTRUCTOR and
+   TARGET_ASM_DESTRUCTOR.
