mrg c0ea06b21f remove MD asm as(1) comments from sysident.h, placing them in a comment
above the asm() block.  now we can share sysident.h across all ports..
change ld.elf_so to be for $MACHINE == sparc64 not sparc (yet!).

mark 719323a7d4 Rewritten the entry code. Use r10 to determine is r0 contains a valid
ps_strings pointer. Use assembly to get argc, argv and argp and then
call __start().

ross 03363828ac No longer needed, calls begin crtbegin & crtend were just removed. 1998-05-06 20:46:56 +00:00
ross cbd1bb578a Sigh, don't make global calls in repeated sharedlib components. It blows
away the dynamic loader.

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.
1998-05-06 05:32:08 +00:00
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

jtc 6351dbac24 Rename initialization and termination functions from __init() and
__fini() to _init() and _fini().  The linker sets the DT_INIT and

lukem 6bf85c9ba3 * use CPPFLAGS instead of CFLAGS for -D and -I options
* use COPTS instead of CFLAGS for -fPIC et al

DESTDIR or programs that assume '_start'.

christos 0e6b23ccbf Put the align directive after .text... 1997-10-15 01:56:55 +00:00
christos 773ab1dd74 Put back __RCSID(): The problem was that if RCSID ended up in the text segment,
it was placed before `start', and start ended up misaligned. Add an alignment
directive for the start symbol. Of course ld(1) should not core-dump relocating
misaligned symbols, but this will be fixed shortly.

jonathan 9b5e38ce15 Un-comment-out "CFLAGS+= -I/usr/src/libexec/ld.elf_so" for new crt0.c 1997-06-24 20:00:45 +00:00
jonathan f4aee0fcbb New, Alpha-derived crt0.c with ld.elf_so support.
Expects additional register-passed arguments from the kernel on
exec().  If no such args ($a0 is zero), fall back to the old hack of
adjusting the current $sp with a hard-coded frame offset for __start's
local frame(!).

Suggested by Jason Thorpe (thorpej@nas.nasa.gov), debugged and
stackframe offsets updated by Jonathan Stone.

cjs 5fd7ce7066 These updates to the build allow building against include files
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.
