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).
On any other system -z means "standard" ZMAGIC format and is the
default. Therefore I've made -z be standard ZMAGIC and -Z be ZMAGIC
stored in the new a_midmag format.
The "standard" ZMAGIC format is now the default as well.
lib.c:
Pull in archives containing definitions needed by shared objects.
warnings.c:
Less spurious "undefined symbol" msgs for shared library defined
symbols.
ld.c:
Do a better job of recognising data in text segments, eg. `const char []'.
shlib.c,ld/rtld/{Makefile rtld.c}
Use strsep() in stead of strtok() and restore colons in eg. env. vars.
to output the same QMAGIC format as BSDI does. This is triggered by
a new '-q' flag ('-Xlinker -q' in gcc). The default can be changed from
ZMAGIC to QMAGIC by defining DEFAULT_MAGIC=QMAGIC when building ld.
ld won't generate output if there are two .o files with the same
name. It thinks they are multiply defined external references. This
patch explictly allows multiple /file names/ with the same value.
This can happen if you do a two stage link or if you link in file
names that are identical to files in libc.
Otherwise ld.c exits with a status=1 and non error message. Rich
