mycroft dedf21f286 Put back code to use pc-relative branches in the PLT, and avoid doing cache
flushes.

mycroft 26fce3548b Use the `first' argument to md_fix_jmpslot(). 1998-12-03 15:46:28 +00:00
matt ce394ac326 Add hook to convert some DISP32 relocs to BASREL through a GOT entry.
[XXX not perfect since gotslot are allocated on a per-symbol basis but
not a per-symbol & addend tuple.  This makes impossible to have separate
GOT entries to ___sF (stdin), ___sF+88 (stdout), and ___sF+176 (stderr)]

matt 931b784473 Remove reference to unused include file. 1998-10-31 08:59:58 +00:00
matt 64f4491c2e Add a hook for converting "normal" DISP32 relocs that refer to data symbols
in a shared object to BASEREL relocs through a GOT entry.

kristerw a2030d670f Revert last change, since it treats external SIZE symbols as
weak undefined symbols. The problem it tried to solve is
actually a bug in non bfd gas.new.

Fixes PR port-i386/6351 from Bernd Ernesti.

matt 8f7b610683 More fixes and optimizations for VAX shared library support. Including
one that makes vfork work.
1998-10-23 00:51:36 +00:00
matt 42ba16dee7 Make the BINDER debug messages a bit more useful (print index and jmpslot
address too).
1998-10-23 00:44:44 +00:00
matt 6ee7d63576 It seems that gas.new has new types to indicate weakness
of symbols.  Adapt our ld to it.

kleink 069e8a5d77 GC empty `FILES' section. 1998-10-20 16:46:15 +00:00
matt 4f1a79cfbd Back out change to md_make_gotreloc which added 4 arguement of got_t *.
Add argument to md_fix_jmpslot indicating whether this the first (i.e
tranfer) jmpslot or not.  Add better support for VAX (the VAX can support
pure text code; let ld that advantage of it).  Checking in verified and
working versions of rtld VAX support routines.

itohy 102d06b78c 1. The 1st arg of sprintf() shall be nul terminated
(The C specification can read as such and our implementation of sprintf()
issues strlen() to the arg).
2. Eliminate memory leaks.
1998-10-17 17:14:01 +00:00

this kluges around some cache issues.

ross d26b3c59c1 Elaborate on --export-dynamic somewhat. Edit -soname. s/ / /, as multiple

ross 9535b6c2a3 Harmonize another ELF linker option: ignore export-dynamic in the COFF linker.
Elaborate on some of the ELF option descriptions, and don't say the options
are ignored...this man page is the one installed on ELF systems, too.

tv 77a275d732 Change ld.so default behavior to RTLD_LOCAL, and make RTLD_LOCAL into a
new flag bit.  Keep RTLD_GLOBAL as an actual flag bit so it won't be
re-used, or may be used for something later.  Mask the dlopen() mode bits
in ld.elf_so so a comparison against RTLD_NOW works.  (RTLD_{LOCAL,GLOBAL}
needs to be implemented for ld.elf_so.)

fvdl 98712f00f0 If a good matching shared library is found, don't look in the next
directories. This is compatible with the SunOS behaviour. Also,
it fixes a problem where it was not possible for some 3rd party
package to have a library with the same name as a library already
in the system, and a lower version number. The highest version
would always be picked. This particular problem shows up with Mozilla,
which has a libutil.so.1.0
