b2695e5a1f arm and sh5 also have bogus DT_TEXTRELs. sh5 was already covered so just 
update the comment.

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.

OK'ed by Charles.

d174ad2eab Add support for shared libraries/dynamically linked binaries on sh5.

run with a fully dynamic userland (modulo a few remaining

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.

0655a07988 Fix bug where only 2/3 of the PLT was being synched with the icache. 
PLT entries are 12 bytes.  Add a #define for that and replace the
explicit values with the PLT_ENTRY_SIZE.  This bug can cause random
SIGILL signals to happen.

fd1f5e8f1b A bit speedup: in _rtld_load_object(), save the number of calls to 
strcmp() by performing path name length comparison first. In the test
with Mozilla, the number was reduced to 1068 from 7182 (yes, we saved
6114 strcmp()!).

044aeabaad Bintuils-current initializes the GOT entries to 0 (instead of the 
base-relative offsets that were placed there previously), so we
must use a different mechanism to compute our reloc base.
