aymeric 6919941456 include <link_aout.h>, which is needed at least when building a cross-linker 2001-07-25 11:59:22 +00:00
aymeric d2b58bf21f Make it possible to compile a cross-linker by just defining TARGET_MACHINE_ARCH 
to the desired architecture.

Note that this is for the old ld of the old toolchain.

jhawk 6f1ea9f65f Fixup comments to account for --{,no-}whole-archive changes. 2000-12-26 01:29:03 +00:00
mycroft bb747bc663 Clean up MAJOR crack addiction: 
--whole-archive and --no-whole-archive are by nature position-dependent.  Make
it so.

matt d87584c459 On VAX, JMPTAB reloc use EXTERN as a type bit. However, they are always 
EXTERN so we always need to emit them.  This fixes various problem with
using JMP instruction in libc and libm.

matt 9816935f22 Remove RELOC_SYMBOLICS_THROUGH_JMPSLOT since it isn't required for VAX (and 
that's why I added it).

mrg a48a4a9a4a forward compatible -rpath-link takes an arguemnt; deal with it. 2000-04-26 02:49:04 +00:00
mycroft 493acb76cb More alloca() -> malloc(). Needed to make some shared libraries link when 
compiled with -g.
 2000-01-13 00:05:32 +00:00
mycroft 9b25bfd178 Semi-random code cleanup. 
Also, in the RRS_PARTIAL case, go ahead and allocate a relocation entry if the
bind failed.  (Who knows?  Maybe some day we'll allow relinking an executable.)

mycroft 5a63d68e02 Fix two problems: 
* On other systems, `-Bsymbolic' does not affect undefined (external)
  symbols at all.  We were generating invalid PLT slots in this case.
* Do not prebind GOT and PLT slots when `-r' is used; only do so if
  -Bsymbolic is used {or if we're in RRS_PARTIAL mode, but I'm not
  sure that's correct}.  Otherwise, we could inadvertantly prebind
  symbols when using `-r' with PIC files; when the resulting .o file
  is then linked into a shared library, the library would not permit
  an executable to override its symbols as it's supposed to.

(Test for good is >= 0.)

tron 5551faab76 Don't abuse alloca() for allocating memory for string sections which can 
easily have a size of several megabytes exceeding the hard stack limit
of some ports. Patch supplied by Richard Earnshaw in PR bin/8547.

pk 564318d090 Fix printf(3) format warning (per Kurt Schreiner on port-sparc). 1999-06-25 12:10:42 +00:00
garbled d1407362ba More and more .Os cleanups. .Os is defined in the tmac.doc-common file, 
so we shouldn't override it with versions in the manpages.  Many more to
come.

this needs a real fix.

itohy 85da239ef8 Fix byte order swapping for cross linker. 1999-01-05 10:02:20 +00:00
cjs a5b9b9c815 Include sys/resource.h, because otherwise RLIMIT_STACK is not set 
and ld does not bump up its stack limit. This causes large links
(such as the kernel) to segfault on machines with a small stack
limit (particularly sparc, .5 MB).

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)]

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.

matt 6ee7d63576 It seems that gas.new has new types to indicate weakness 
of symbols.  Adapt our ld to it.

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.
