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.

PLT entries are 12 bytes. Add a #define for that and replace the

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.

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.
