The PLT symbol is also a special case when processing a shared library
...
symbol table (and so is the GOT symbol actually, but no one ever noticed..).
Re-enable PLT symbol.
1998-09-04 09:43:29 +00:00

Disable the the PLT symbol until I can get it to work properly.

Create symbol for __PROCEDURE_LINKAGE_TABLE_.

Get md.c to compile again. Get mdprologue.S to assemble. [Now at least

ld and rtld compile and link.]

Untested(!!) beginning of VAX a.out shared library support. This is a work

Don't reset the reloc_index when we patch a jmpslot. We don't need to, and
...
this kluges around some cache issues.
1998-07-27 07:48:21 +00:00
d26b3c59c1
Elaborate on --export-dynamic somewhat. Edit -soname. s/ / /, as multiple
...
spaces are magic and unpaddable in troff.
1998-07-26 02:51:59 +00:00

Remove bogus change to use -O0.
1998-07-25 12:37:27 +00:00

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.
1998-07-25 11:58:49 +00:00
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.)
1998-07-14 22:18:36 +00:00

Clear the error indicator after retrieval (xref. dlerror(3)).

In case NOPICINSTALL is set, get -lc_pic from src/lib/libc/(objdirname).

Optimize symbol/string table access slightly by precomputing their
...
locations at load time. These values don't change once the object is loaded.

Need <dlfcn.h> for Dl_info.

Implement `dladdr()': find nearest symbol given an address.

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

Allow a non-RTLD_GLOBAL object to refer to symbols in itself.

Use file size from fstat(2) to map the hints file, instead of fiddling
...
with incremental mmap()'s. Squashes a bug which caused only the first
page of the hints file to unmapped.
1998-03-18 23:21:46 +00:00

Implement RTLD_GLOBAL dlopen(3) flag.
...
Rename internal flags to avoid <dlfcn.h> name space collisions.

Add emulation of binutils 2.x ld options:
...
-rpath dir, -shared, -soname, --whole-archive, --no-whole-archive
for compatibility with ELF ports and to aid migration to bintils.
Update manpage with new otions.

Print a warning message if we detect that a "copy symbol" has changed
...
size in a shared library. Also, always use our expected size to copy
the item in, on the assumption that doing so generally minimizes the
damage (maybe it's better to just bail out?).

bsd.prog.mk isn't needed here, and including it only gets us an
