# $NetBSD: crtbegin.S,v 1.2 1998/05/06 05:32:08 ross Exp $
|
|
#
|
|
# Warning --
|
|
#
|
|
# This module has been modified by hand from a prototype crtbegin.c
|
|
# for the purpose of the following low-level mechanisms:
|
|
#
|
|
# [1] Fall through the .init section from _init() to a return block
|
|
# in crtend(). This allows compilers for object-oriented languages
|
|
# to generate inline initialization code. The mechanism is an
|
|
# alternative to the one presently used by g++ for file level
|
|
# constructors and destructors. It is apparently the original
|
|
# intention of the ELF .init and .fini segments that this option
|
|
# be open to compilers. Work based on a suggestion by jtc@netbsd.org.
|
|
#
|
|
# [2] The incorrect cross-elf-section bsr was fixed, this had
|
|
# the side-effect of limiting program text size to 4 MB.
