From 02d8afd50a868e827ac8b6b6243c69922cd694ed Mon Sep 17 00:00:00 2001
From: Mahesh Bodapati <mbodapat@xilinx.com>

Subject: [PATCH] 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.
