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.

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

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.

c7a4944620 update so this compiles with the latest ELF ld.so. Include bsd.own.mk

cccb7a88b4 Reimplement in C, adding ELF support. if compiled with -DECOFF_COMPAT 
(currently the default), then it compiles on both an ECOFF toolchain
and on an ELF toolchain (but w/o support for dynamic linking or C++
constructors & destructors).  If compiled without -DECOFF_COMPAT, it
supports statically- or dynamically-linked ELF binaries (and shared
libraries).
