kleink fc5695807b Bump _start() alignment to 4 bytes. 1999-08-23 09:10:23 +00:00
matt 741f18b695 Initial VAX ELF32 support (mostly untested). It's checked primarily for
testing and archival for now.  I don't expect anyone to work with it
since the binutils and gas changes are still pending.  But you got to
crawl before you walk.
1999-08-21 19:26:18 +00:00
kleink b9f86eb3a1 Namespace cleanup: move runtime linker interface into implementation namespace
and provide weak aliases.
1999-08-19 20:52:36 +00:00
fvdl 3cf76a4d16 Add _start (as well as __start). It's the default start symbol expected
by ld for the i386 ELF case.

kleink 196becef81 Declare dlerror()'s return value __aconst. 1999-05-19 14:50:49 +00:00
kleink 28d76befd4 When calling dlerror() in a non-dynamically linked executable, return a pointer
to an error string rather than NULL (`no errors occured) to indicate the cause
of failure return values of other dl*() interfaces.

kleink faa2202a49 Use __weak_extern() instead of an asm statement. 1999-05-02 18:26:43 +00:00
simonb 45c86b888b Instead of rolling our own "install" target, use FILES/FILESDIR and
LINKS to that things like "make install UPDATE=" work properly.

thorpej cb3c96c11e Pull together common Makefile fragments for ELF crt0 files, and use it
across the board.
1999-03-20 00:32:40 +00:00
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).

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.

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 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.

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.

cgd 6da04f404e expect a 'struct ps_strings *' as the fourth argument to __start.
If it's there, i.e. doesn't have a value known to be emitted by kernels
which didn't include support for passing it (0 or 0xbabefacedeadbeef),
set __ps_strings to it.  Otherwise, use the old 'normal' PS_STRINGS value
for __ps_strings.
