matt eef4b63246 Make __start global. 2001-09-08 18:59:20 +00:00
bjh21 751e6fa590 Ensure that the stack is aligned to an 8-byte boundary before calling C code.
(ATPCS B-01)
2001-08-17 00:14:38 +00:00
simonb 9a68629ca6 Enlarge the stack frame to 16 bytes, and store the return address 8
bytes in instead of at the start, to leave room for a .cpload to store
the gp at offset 0 in the frame.  Allow 8 bytes for each (for mips64
one day...).

.cpload overwrite problems noted by Michael Hitch.
2001-08-16 03:44:46 +00:00
matt ee6a16ad18 Add a secondary label called __start (makes gcc 2.95.3 happier) and rename
the internal __start to ___start.   (Since -e is not supplied by default,
this has no effect on a native build.)

thorpej 102df4197d Enable DWARF2 EH support. Confirmed working w/ GCC 2.95.3 on sparc
and i386.
2001-08-03 14:26:13 +00:00
thorpej a6855eea24 Add support for DWARF2 frame unwinding/exception handling. This
should be sufficient for GCC 2.95.3, and probably GCC 3.0 as well.

Not yet enabled by default; further testing required.

kleink 7bd28edec7 Add, but do not yet enable, m68k code for .init and .fini section fallthroughs. 2001-05-12 00:17:55 +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.

mycroft 8f3189af13 Trivial change. 1998-05-06 09:30:26 +00:00
ross ab2c05e5a3 Eliminate incorrect gcc-generated cross-section bsr's by calling the static
constructor/destructor dispatcher via a function pointer protected from
constant propagation. Also, create (presently unused) .S files that solve
the same problem and in addition allow in-line .init section and .fini
section code. This is too big a mod for a 3.2 pullup, however.

ross bb44cd0d28 Put the vanilla versions of these into CVS so that Those Who Come Later
can see the hand assembly mods in a cvs diff rather than having to start over
from the prototype .c files. (Although these will also be available.)

mrg 2e9c82f79d build standard NetBSD/ELF crt{begin,end}.o files, clean up some egcs warnings. 1998-05-02 21:26:54 +00:00
matthias 10f833afad Move rcsid so that executables start with code again (that's just
tradition, not really necessary).

cgd c0ac8bae67 GC alpha's ECOFF_TOOLCHAIN make variable, and related bits. Nobody
should be using an ECOFF toolchain on NetBSD/alpha any more.

jtc 6351dbac24 Rename initialization and termination functions from __init() and
__fini() to _init() and _fini().  The linker sets the DT_INIT and
DT_FINI .dynamic section entries based on the latter names.
1998-03-27 09:11:33 +00:00
matthias 77aae84af4 Undo last change. Global register variables really have to be declared
as register variables...

pk 49c810b2c8 Avoid spurious calls to foreign constructors/destructors in case the
shared library we link with does not have any of its own.
Note: this only works for a.out(5).

lukem cc8d1d3968 use a common Makefile.csu.aout for the a.out ports 1997-10-27 01:03:39 +00:00
thorpej 07de56201a Fix think'o in previous. 1997-10-24 21:18:25 +00:00
lukem fa2de9fb4c use ${.CURDIR}/${SRCS} instead of ${.ALLSRC} (from i386/Makefile) 1997-10-24 00:35:22 +00:00
christos 88d2078c4f Revert previous change ${.ALLSRC} will contain .h files etc. 1997-10-23 21:42:54 +00:00
lukem 6bf85c9ba3 * use CPPFLAGS instead of CFLAGS for -D and -I options
* use COPTS instead of CFLAGS for -fPIC et al
* use ${COMPILE.c} instead of ${CC} ${CFLAGS} -c
* use FILES and FILESDIR to install pc532 objects (instead of install: rule) -
  this makes it consistent with the other a.out ports (arm32, i386, m68k, sparc)
1997-10-22 16:00:39 +00:00
