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.

Shorten rtld_start() by 2 instructions or 8 bytes, and make it not use GOT

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.

Eliminate GOT usage in rtld_start() on this platform, too.
2003-02-28 22:37:35 +00:00
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
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.

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
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.

Put back the short-circuiting code -- Matt claims there are functions that rely

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.

Allocate space for the argument space area in both _rtld_start() and
