130ab7336b Rework how MAKEVERBOSE operates: 
*	Don't bother prefixing commands with a line of  ${_MKCMD}\
	and instead rely upon "make -s".  This is less intrusive on
	all the Makefiles than the former.  Idea from David Laight.

    *	Rename the variables use to print messages.  The scheme now is:
	    _MKMSG_FOO		Run  _MKMSG 'foo'
	    _MKTARGET_FOO	Run  _MKMSG_FOO ${.TARGET}
	From discussion with Alistair Crooks.

323a574dc3 dlsym() should not leave an error set. It confuses programs that check 
dlerror() (such as pkgsrc/graphics/transcode).

d900731978 Resolve dlsym(3) and friends directly so that dlsym(RTLD_NEXT,...) works. 
Previously dlsym resolved to the version in crt0.o or libc which would
mean that the caller's shared object couldn't be determined correctly
using __builtin_return_address(0).

Mainly from FreeBSD, but adapted by me. Benefits of this solutions are:

	- backward comptibility maintained
	- existing broken binaries are fixed with a new ld.elf_so
	- __mainprog_obj can be removed from crt0.o
	- we do the same thing as FreeBSD

Fixes PR 22067.

OKed by Jason and Christos.

619dee76f6 Correct the in_plt parameter of a couple of _rtld_find_symdef calls. 
The mips_reloc.c case is a no-op as _rtld_symlook_obj ignores in_plt for
MIPS.

entries.

d2fd5f837d Shorten rtld_start() slightly -- there's a base-relative _DYNAMIC pointer at 
the beginning of the GOT, so we don't need an extra one here.  Also, remove a
bogus comment -- we do in fact have to do fixups, because there are pointers in
ld.elf_so's data segment that need to be relocated.

527c1efca7 Use the "__NetBSD_Version__" constant rather than the "NetBSD" constant 
in the NetBSD version note.  The old "NetBSD" constant was stuck in stone,
and thus didn't really convey any useful information.

9cb7d16b11 Similar to other rela platforms, do not use any GOT entries (other than the 
first entry, which is a special case) in rtld_start, because they could be
all 0s.  Instead we use the difference between the real _DYNAMIC address
(which we can determine on 68k with a "lea (%pc,_DYNAMIC),..." and the
base-relative one (at the beginning of the GOT) to figure out the relocation
offset.

Not needed for binutils-current, but I might as well fix it now.
 2003-02-28 07:06:16 +00:00
mycroft
eea1001a73 Adjust for the fact that the GOT is all 0s in new binutils -- do the trick of 
disassembling a call to _DYNAMIC to determine its real address, and using the
first entry of the GOT as its base-relative address.

It's evil, but it works.
