e8e41d4cf8 Bring ia64 back from the dead. After a call one needs to restore the
GP register, because it's clobbered for calls across load modules. The
previous commit inserted the call to _init_tls() between the call to
atexit() and the restoration of the GP register clobbered by it. Fix:
restore GP before we call _init_tls().

68d0d87b81 _start() needed to be written in assembly. See crt1.S. 2003-07-14 03:05:42 +00:00

db7ffe67c6 Rewite _start(). We cannot use a C function due to the fact that we
don't call it according to the runtime specification and especially
WRT to gp this can cause trouble. The gcc 3.3.1 import broke the
ia64 runtime because the compiler saved gp prior to us being able
to set it properly. Restoring gp after the calls would then invalidate
gp and cause segmentation faults later on.
By rewriting _start() as an assembly function, we also avoided even
more gcc dependences, by trying to use gcc specific features to work
around the problem.
This version of _start() does not reference _DYNAMIC. We register the
cleanup function when it's a non-NULL pointer. The kernel will always
pass a NULL pointer and dynamic linkers may pass a non-NULL pointer.

The machine independent code to set __progname now unfortunately is
written in assembly. So be it.

818c8b696b make these more useful for lint(1). Minor diff-reductions while I'm
about it.

828191256b The main reason for this is to reduce diffs between all the crt1.c's.
Assembler macros are tidied up and made as similar as sanely possible.
The macros are translated into C (__inline static) functions for lint.

Declaration orders are made the same.
Declarations are all ISOfied and tidied up.

Comment contents have gratuitous diffs removed.

The net result is a bunch of crt1.c's that are 90% the same.
It may be possible to now encapsulate the differences in one
MD header, and have only one MI crt1.c file (although the macros
to do this may be ugly).

2a53f3fb35 Major cleanup of bsd.lib.mk.
Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything.  Added a NOINSTALLLIB knob for libpam/modules.  To not
build any library at all, just do not set LIB.

4cd0119367 Do not use __progname directly (except in [gs]etprogname(3)).
Also, make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.

b3cd898e58 Mostly cosmetic. Use indentation that is reasonably close to other
ia64 *.S files in our tree (eg: locore.s).  Put the rest of the args
in the .section lines.

16ef3f735a Update for the new toolchain. ld doesn't provide _GLOBAL_OFFSET_TABLE_
in 2.11.2, so use a relocatable method of calculating gp.

c91cd68318 Add missing crti.S and crtn.S files. I have tested these with -static
linking only.  They may require some gp relative tweaks for dynamic use.

ae7c8a2bb8 * Bring back the guts of crt{i,n}.S. This allows C++ exceptions to work
when using the egcs and gcc-devel ports, along with GCC built from stock
public FSF sources.  With out this change, FreeBSD will be removed from
the list of systems GCC 3.0 must be evaluated on before release.  With
the effort some of us put into getting FreeBSD on this list, we should
not turn this effort into a waste, else we might not be worth fighting
for in the future.  (note that Alpha and IA-64 versions of crt{i,n}.S
are needed)

* Switch from our own crt{begin,in} to those created from GCC's crtstuff.c.
This will allow us to switch to DWARF2 exceptions in the future, along with
staying in sync with any future GCC requirements.

* Break out our ELF branding bits into a seperate file.  Currently this
is now included by our crt1.c files (since this functionality was part of
our native crtbegin.c).  Later crtbrand.o will be merged in the creation
of crti.o.
