From 204772eb9cf51b539eb07fc4aa8beba0a971e6a4 Mon Sep 17 00:00:00 2001 From: Chris Demetriou Date: Fri, 11 Aug 2000 03:18:05 +0000 Subject: [PATCH] elf.h (CTOR_SECTION_NAME, [...]): New macros define the name of CTOR and DTOR sections. * mips/elf.h (CTOR_SECTION_NAME, DTOR_SECTION_NAME): New macros define the name of CTOR and DTOR sections. (CTOR_LIST_BEGIN, CTOR_LIST_END, DTOR_LIST_BEGIN, DTOR_LIST_END): Change to use attributes to specify sections. * mips/elf64.h (CTOR_SECTION_NAME, DTOR_SECTION_NAME, (CTOR_LIST_BEGIN, CTOR_LIST_END, DTOR_LIST_BEGIN, DTOR_LIST_END): Same as in mips/elf.h.
