matt fd1caff7c2 Update to new reality. XXX _rtld_bind still needs to be written. 2003-10-06 16:08:35 +00:00
mycroft 65ed3bdcdd Make the effect of the hack clearer. 2003-09-24 10:25:26 +00:00
mycroft 7242c1114c One more tweak... 2003-09-24 10:18:52 +00:00
mycroft 7b234fd232 Make the comment a little more accurate. 2003-09-24 09:59:45 +00:00
mycroft 89ea37c60a Temporary workaround for some binutils/ld lossage. See the comment for more
information.

mrg 88bb1d9b3b include <string.h> or <stdlib.h> for all prototypes 2003-07-26 15:04:38 +00:00
skrll 5f573ab68d ANSIfy and de-__P(). 2003-07-24 10:12:25 +00:00
skrll ddc9322f3b Support immediate binding on arm. 2003-07-21 15:34:35 +00:00
skrll 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.

marcus fae2567c9b Removed unused function. 2003-07-05 20:48:39 +00:00
tsutsui 0e65101f60 Add function prototype declarations. 2003-07-05 18:18:51 +00:00
marcus a4878b4349 Bugfix: Don't pick addend both from reloc and contents at the same time. 2003-07-02 15:29:34 +00:00
marcus 6aeeb40d4a Updated to work with current rtld code. 2003-06-30 00:50:46 +00:00
petrov 458dbd70ac Fix alignment problem in debug output.
Happens only under RTLD_DEBUG_RELOC.
2003-05-23 20:13:50 +00:00
scw 0b8f02edad Handle unaligned relocations, and RELATIVE relocs with non-zero addends.
This gets binaries linked against libstdc++ working (FSVO "working").
2003-04-21 11:54:46 +00:00
scw e6b13790fa SH5 needs __HAVE_FUNCTION_DESCRIPTORS defined in order for ld.elf_so
to resolve SHmedia function pointers correctly.
2003-03-26 14:46:32 +00:00
scw d174ad2eab Add support for shared libraries/dynamically linked binaries on sh5.
With the latest SuperH toolchain, NetBSD/evbsh5 can now
run with a fully dynamic userland (modulo a few remaining
gremlins affecting a couple of binaries).

mycroft 7cbba1750d Shorten rtld_start() by 2 instructions or 8 bytes, and make it not use GOT
entries.
2003-03-02 22:56:14 +00:00
mycroft 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.

mycroft 33131cb294 Update copyright. 2003-03-01 15:14:59 +00:00
mycroft 9939b38056 Eliminate GOT usage in rtld_start() on this platform, too. 2003-02-28 22:37:35 +00:00
mycroft 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.

mycroft c42fd7b479 Revert previous change. 2003-02-21 01:12:56 +00:00
matt 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.
2003-01-11 01:33:56 +00:00
thorpej 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.

Patch from Charles Hannum.

fvdl 100e201ec6 Replace return -1 in rtld_bind with _rtld_die() call. 2002-11-24 18:19:23 +00:00
fvdl d93db1cfce Implement self-relocation as is required now. 2002-11-24 18:16:45 +00:00
matt 01ba93bc3c Convert to register prefixes. 2002-10-31 20:23:25 +00:00
thorpej b777dba640 _rtld_bind(): Don't use "rela" until after we've (potentially) adjusted
it.
2002-10-18 20:35:25 +00:00
mycroft ad8ccd6290 Minor cleanup. 2002-10-05 11:59:03 +00:00
mycroft 4172074119 Skip the lazy PLT relocation if relocbase==0 (useful if libraries are loaded
at their VMA address).
2002-10-03 20:39:22 +00:00
mycroft 0a20e1e977 We don't need to save r7, either... 2002-09-27 03:46:12 +00:00
mycroft b95736d94a Put back the short-circuiting code -- Matt claims there are functions that rely
on it.
OTOH, don't bother saving r6 a second time.
2002-09-27 03:34:22 +00:00
mycroft 6d8d08304c 1) There is no reason to flush the I$ here, given that we do not modify any
instructions.  Function calls use GOT indirection, and we only patch the
   GOT.
2) The mask-comparison optimization always fails, because the saved mask
   always has 0x2000 set, and the PLT stub mask never does.  So, remove it.
2002-09-27 02:46:05 +00:00
mycroft 42fb5b53c2 Save one more instruction. 2002-09-27 02:14:38 +00:00
mycroft 06f9fa98b0 Save relocbase in %r10, not %r1.
Also, save one instruction.
2002-09-26 23:28:52 +00:00
mycroft d437f6520b Implement a self-relocate function for the VAX. 2002-09-26 22:26:26 +00:00
mycroft 1c495430dd Remove the `self' args to _rtld_relocate_objects() and
_rtld_relocate_nonplt_objects().
2002-09-26 20:42:10 +00:00
mycroft 7d4bbc7f4e Add an iffy heuristic that allows us to do lazy binding with new objects, but
detect old objects and deal with them.
2002-09-26 20:41:34 +00:00
mycroft 15025431b4 Update a comment. 2002-09-26 03:25:29 +00:00
mycroft fd7e0d92f3 Add a rdbg() in _rtld_bind(). 2002-09-26 02:52:05 +00:00
mycroft 723a5f8a50 Remove a meaningless bit from a rdbg(). 2002-09-26 02:51:27 +00:00
mycroft ee398b4d07 Remove vestigal comments about _rtld_bind_start_0() -- it works now. 2002-09-26 02:25:57 +00:00
mycroft 26043b23b0 Make room for the argument save area in _rtld_start(). The PLT stub already
made room from _rtld_bind_start(), but add a comment explaining the instruction
it uses.
2002-09-26 02:14:10 +00:00
mycroft f1c792d648 Make the stack frame 96 bytes, like GCC does. 2002-09-26 02:05:41 +00:00
mycroft bde7a965da Tweak the save instruction in the PLT stub rather than adding an instruction
to the binder entry stub...
2002-09-26 01:59:16 +00:00
mycroft d314d82b47 Allocate space for the argument space area in both _rtld_start() and
_rtld_bind_start().  Not needed normally, but if we compile ld.elf_so with
-g, it blows up without this.
2002-09-26 01:54:52 +00:00
mycroft 6bff9ffc3d For consistency, use Elf_Word* to point to code, not Elf_Addr*. 2002-09-25 22:33:54 +00:00
mycroft 0079455251 Add a comment explaining some of the magick. 2002-09-25 22:29:12 +00:00
