jonathan 338a11a3e7 RCSid police. Add __RCSID while we're here.
Add alternate label '_start' in front of __start() for installs with
DESTDIR or programs that assume '_start'.
1997-10-20 03:24:49 +00:00
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.

set __ps_strings to it.  Otherwise, use the old 'normal' PS_STRINGS value
for __ps_strings.

cgd 53ded8ebcb add a hack so that old- and new-toolchain alphas do the right thing:
include bsd.own.mk early on, and if !alpha or if !ELF_TOOLCHAIN,
build c++rt0.o.  ELF alphas don't use the 'normal' C++ runtime startup
routines.  Eventually, there should be better ways to distinguish what
toolchain and object format is in use, and the Alpha C++ startup code
changes should be merged with that used by the other ports.
1996-10-08 00:36:28 +00:00
cgd c7a4944620 update so this compiles with the latest ELF ld.so. Include bsd.own.mk
at the top, for ELF_TOOLCHAIN definition, so this can be better
conditionalized for new/old toolchains.

constructors & destructors).  If compiled without -DECOFF_COMPAT, it
supports statically- or dynamically-linked ELF binaries (and shared
libraries).
