thorpej 5b81869561 Don't use multi-line string literals; they're not supported by ANSI C. 2001-12-30 23:23:38 +00:00
thorpej 4abcdae85e Enable the new (working) .init/.fini magic. 2001-07-17 03:56:48 +00:00
ross 2d62241cb9 Reorganization of crtbegin/crtend.
o  Primary mod: alpha and i386 code for .init and .fini section fallthroughs
o  Actual fallthru is not yet enabled, see csu/{alpha,i386_elf}/Makefile
o  When enabled, should fix bin/12865 & should fix at least one WINE bug,
   see http://www.winehq.com/hypermail/wine-devel/2001/05/0021.html
o  Also, removed the function pointer hack put in to prevent gcc from
   incorrectly attempting to do short calls over section boundaries,
   on some architectures, rather, simply simply move ctors() and dtors()
   into .init and .fini.
Other notes.
o  Our crtbegin.c and crtend.c were completely in C, despite
   the fact that .init and .fini section fallthroughs require machine code.
   These modules implement the gnu ctors/dtors mechanism directly, eliminating
   in part the need for the elf .init/.fini section fallthrough. However,
   if we ever want to use the gnu-provided constructor support, we need to
   do the fallthrough, at least one program (WINE) apparently uses the
   feature independently, and other compilers may depend on the mechanism.
o  It is amusing that the previous NetBSD _init() and _fini() were put
   into the .init and .fini sections, because nothing is gained over
   plain .text if they don't fall through. Cargo cult!
o  Other elf ports will need to copy the alpha and i386 example mods.

cgd c85d2eb42b sweep of my licenses for consistency. (no functional changes) These
files have copyright held by people in addition to myself.  (I did the
original work, they copied it, enhanced it, and added their copyright
to the derivative work.)  Their approval has been given re: the license
change.

cgd d220ca5ba3 fix up NetBSD RCS Ids to match the standard, and the leading comment as
to match as well.  No functional changes.

lukem fe5a2bf74b remove the ``static'' from `static void __start()' and `static void ___start()'
because an overly aggressive gcc -O3 "cleverly" optimizes the functions out.
noted in [port-i386/8493], but seen in other ports as well.

kleink fc5695807b Bump _start() alignment to 4 bytes. 1999-08-23 09:10:23 +00:00
fvdl 3cf76a4d16 Add _start (as well as __start). It's the default start symbol expected
by ld for the i386 ELF case.

thorpej cb3c96c11e Pull together common Makefile fragments for ELF crt0 files, and use it
across the board.

thorpej 0d19945594 Collect the top parts of the ELF crt0.c files into a common header, and
use it across the board.

crt0.c now contains stuff that REALLY IS machine-dependent, or stuff that
is completely intermingled in machdep code (and thus can't be separated
easily).

thorpej 3f196ccbc8 Put a good chunk of code common to all ELF crt0.c files into a common
location, and use it.

thorpej 4216363b47 Move crtbegin.c and crtend.c from alpha subdir to common_elf subdir via
repository copy, remove all redundant copies of these files, and make all
ELF platforms use the common versions.
