Use `install -C' instead of lots of shell commands to install ld.so as atomically as possible. (Immutable targets can't be renamed without opening a window when neither the source nor the target is immutable. Perhaps there should be a rename_immutable syscall to do this if unsetting the immutable flags would work.) 1996-09-12 03:42:54 +00:00			`# $Id: Makefile,v 1.19 1996/05/07 23:15:58 wosch Exp $`
Imported NetBSD's ld for shared libs. 1993-11-03 23:41:59 +00:00
			`PROG= ld.so`
This is Paul K's latest set of ld changes. A commit was necessary at this late stage due to the fact that link.h was copyright Sun Microsystems. This version of ld sync's us up with NetBSD's ld and supports compatablily with NetBSD's -[zZ] flags (which we had reversed). Compiling with this new ld will give you RRS warnings for libraries which do not contain .type infomation - these wsarnings are harmless and will go away as soon as you recompile your libraries (cd /usr/src; make libraries). 1994-02-13 20:43:13 +00:00			`SRCS= mdprologue.S rtld.c malloc.c shlib.c etc.c md.c`
Import Paul Kranenburg's man page for ld.so (aka. rtld). Obtained from: NetBSD 1995-08-26 13:17:39 +00:00			`MAN1= rtld.1`

Add dependencies on libraries to DPADD. Someday this should be done automagically. -lfoo has to be right to work, but ${LIBFO0} is too easy to forget or misspell; nothing checks it and it should be different for shared libraries. 1994-08-28 18:49:06 +00:00			`DPADD+= ${LIBC:S/c.a/c_pic.a/} ${LIBC:S/c.a/gcc_pic.a/}`
Due to the deletion of the gcc support from libc we need again the -lgcc_pic library. rtld uses the udivd3 routine from it. Repeat the bug by simply compiling ld on current. 1994-03-10 23:19:54 +00:00			`LDADD+= -lc_pic -lgcc_pic`

Weak symbol support from NetBSD. This should bring us in sync with the NetBSD ld code except for local changes for dlopen() and friends and the hashing on the minor value of the shlibs. We should be binary compatible now with all their libraries. Obtained from: NetBSD 1995-03-04 17:49:20 +00:00			`$(LD) -o $(PROG) $(LDFLAGS) $(OBJS) $(LDADD)`
