From 57fb889f4199e7ffedc756e9d729d62171fb91f9 Mon Sep 17 00:00:00 2001 From: Ajit Agarwal Date: Mon, 18 Aug 2014 17:04:41 +0000 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. ChangeLog: 2014-07-28 Ajit Agarwal * config/microblaze/microblaze.c (microblaze_elf_asm_cdtor): New. (microblaze_elf_asm_constructor,microblaze_elf_asm_destructor): New. * config/microblaze/microblaze.h (TARGET_ASM_CONSTRUCTOR,TARGET_ASM_DESTRUCTOR): New Macros.
