pk d579c1b1db Handle object code with the "large" model PIC (eg. gcc's `-fPIC' option). 1995-08-04 21:49:00 +00:00
pk 05a6a13e75 Be sure to calculate correct offsets in dispatch table. 1995-06-05 01:01:51 +00:00
pk ad760ce3d6 Implement compiled-in library search paths: any `-L' argument encountered 
while `dynamic link-mode' is on, is recorded in the executable. The
run-time linker will search these paths after $LD_LIBRARY_PATH but
before the default set and those currently in the hints file.
The feature is disabled whenever for set[ug]id programs.

pk 8e0a22a5fb "weak symbol" support (fudged into `a.out' by means of the n_other field). 
Weak symbols are to replace indirect (type N_INDR) symbols and will help
to clean up name spaces in libraries.

Also, some misc. bug fixes, including PR 586, and use stdio for the output
file entirely.

pk c76144bbf8 Postpone allocation of linkage table offsets until pass 2. 
Check for Global Offset Table overflows and, if needed, adjust the
offset range we'll use (offset 0 must always be in it).
 1994-08-21 15:22:43 +00:00
pk f5ca392cc8 Propagate warning symbols into shared libraries too. 
Fix RRS relocation counters.
 1994-07-23 08:40:45 +00:00
pk a6bf4f8176 Conversion to err()/warn() for error reports. 
Minor bug fixes:
	a case of free()ing in the wrong order. (from Rick Murphey).
	processing alias symbol twice (sometimes).
Some miscellaneous cleanup.

pk 12f28a9ba6 PC relative segment relocations don't need to be looked at at run-time (such 
relocations occur on the ns32k).
Dump <strings.h> from header files.
 1994-04-07 19:41:17 +00:00
pk b120bb4e37 Suck in lseek() prototype. 1994-03-31 14:17:29 +00:00
jtc fc1d8f3bac Fix spelling error in Copyright notice 1994-01-29 01:54:01 +00:00
pk 90cfba21cb Use `.type' directives generated by gcc. 
Numerous internal changes & bug fixes.
NOTE: must re-compile & re-link shared libraries before used to link programs.
 1994-01-28 20:56:09 +00:00
pk fa099af1f6 Many internal changes, most notably in the symbol counting stuff. 
`ld -r -x'  now supported on all object files.
Support for long archive member names (AR_EFMT1 format),
	thanks to Bill Sommerfeld/Mark Eichin
Do the right(?) thing with symbol aliases (N_INDR) for POSIX lover, especially
when equiping shared libraries with these (this was *not* fun).
Handle silly archives (.sa) for people who needs them; turn on by `-Bsilly'.
 1993-12-08 10:13:47 +00:00
pk e5b3eedefb Eleminate duplicate inclusion of shared objects (libgcc!). 
Start using auxiliary information (using `n_other') to tackle aliasing of
function addresses and direct function calls in shared objects.
NOTE: currently protected by `#ifdef EXPERIMENTAL'.
 1993-11-10 21:53:30 +00:00
pk 94aab0b5fc The N_SET* symbols are back in. C++ object files can now be linked again. 
(not yet fit for *shared* C++ libraries).
 1993-11-01 16:26:13 +00:00
pk 4aa8c26f37 Improved handling of PIC code in "main stream" .o files. 
Don't touch __DYNAMIC when `-r' is on.
Now must use `-Bshareable' to make shared libraries.
 1993-10-27 00:53:39 +00:00
pk 05d16c3379 relocation for non-RRS shared library symbols wasn't always set correctly. 1993-10-22 21:00:08 +00:00
pk 69af39d0a8 No rounding of bss size to page boundary in ZMAGIC a.out's, the kernel 
chokes on it.
Some other minor changes.
 1993-10-21 00:52:52 +00:00
pk 97ca10e374 A linker supporting shared libraries. 1993-10-16 21:52:27 +00:00
