Alan Modra 4613510308 Change ld "notice" interface for better handling of indirect symbols
The main aim of this change was to have non_ir_ref set correctly on
new indirect symbols.  I could have added a "copy" param to the "notice"
function, so that indirect symbols could be created in plugin_notice,
but it seemed cleaner to create indirect syms earlier and pass them
rather than "string" to "notice".

include/
	* bfdlink.h (struct bfd_link_callbacks <notice>): Remove "string"
	param, add "inh".
bfd/
	* coff-aux.c (coff_m68k_aux_link_add_one_symbol): Only call "notice"
	here when not calling the generic add_symbol function.  Formatting.
	Correct handling of indirect symbols.  Update notice call.
	* elflink.c (_bfd_elf_notice_as_needed): Update notice call.
	* linker.c (_bfd_generic_link_add_one_symbol): Create indirect
	symbols early.  Update notice call.  Add comments regarding weak
	symbols vs. indirect.
ld/
	* ldmain.c (notice): Update args.
	* plugin.c (plugin_notice): Likewise.  Follow warning sym link.
	Handle new indirect symbol.

H.J. Lu 144bed8d4d Properly match PLT entry against .got.plt relocation
Relocations against .got.plt section may not be in the same order as
entries in PLT section.  It is incorrect to assume that the Ith reloction
index against .got.plt section always maps to the (I + 1)th entry in PLT
section.  This patch matches the .got.plt relocation offset/index in PLT
entry against the index in .got.plt relocation table.  It only checks
R_*_JUMP_SLOT and R_*_IRELATIVE relocations.  It ignores R_*_TLS_DESC
and R_*_TLSDESC relocations since they have different PLT entries.

Max Filippov e7d17e71cd Fix xtensa ld segfault when linking linux modules
is_inconsistent_linkonce_section makes an assumption that section name
that starts with ".gnu.linkonce.prop." has one more dot in its suffix.
However gas generates such section name by insertion of "prop." right
after ".gnu.linkonce." part of the name of the original section. So, for
section named ".gnu.linkonce.this_module" corresponding property section
name does not satisfy the assumption. Such section names are common in
linux modules. This bug was exposed by the patch "a35d5e8 Fix alignment
for the first section frag on xtensa", that makes gas produce property
section for each section that has ".align" directive in it.

Use suffix that immediately follows ".gnu.linkonce.prop." when there are
no more dots following it.

Alan Modra bffebb6ba5 Copy st_other for linker script symbol assignments
This fixes a problem seen on powerpc64le ELFv2 when creating a

from the source symbol to the alias in order to set up the local entry

that use st_other bits might benefit too.

Jiong Wang 2e0488d33f Enable elf_backend_rela_normal for AArch64
If we are generating non-relocatable object and --emit-relocs specified,
  aarch64 ld is actually generating wrong addend for rela entry when
  relocate against local symbol.

  for example, for simple testcase

  foo.c
  ===

  const char * const a = "foo";

  const char *
  foo ()
  {
    return a;
  }

  bar.c
  ===

  const char * const b = "bar";

  const char * bar ()
  {
    return b;
  }

  aarch64-none-linux-gnu-ld --emit-relocs -o x.o  foo.o bar.o
  aarch64-none-linux-gnu-readelf -r x.o

   ... R_AARCH64_ADR_PRE 0000000000400018 .rodata + 0
   ... R_AARCH64_ADD_ABS 0000000000400018 .rodata + 0
   ... R_AARCH64_ADR_PRE 0000000000400018 .rodata + 0
   ... R_AARCH64_ADD_ABS 0000000000400018 .rodata + 0

   while it should be:

   ... R_AARCH64_ADR_PRE 0000000000400018 .rodata + 0
   ... R_AARCH64_ADD_ABS 0000000000400018 .rodata + 0
   ... R_AARCH64_ADR_PRE 0000000000400018 .rodata + 10
   ... R_AARCH64_ADD_ABS 0000000000400018 .rodata + 10

   bfd generic code could actually handle this properly, but only when
   elf_backend_rela_normal set to '1'.

   this patch enable this and remove those target specific hack.

Objects built with -fno-fat-lto-objects (the default for gcc-4.9) have
no normal symbols, except things like __gnu_lto_slim.  These useless
symbols are the ones put into the archive index, and of course nothing

ar with --plugin changes ar behaviour to put the lto symbols into the
archive index.

Alan Modra 7341d5e22f Add symbols for global entry stub, and report stats
The undefined function symbols (with non-zero value) on global entry
stubs are discarded by objdump when disassembling, so give objdump
another symbol to mark the stubs.

Also fixes a couple of bugs:
- entry_section was set to .opd for ELFv2, which meant a hard error
  rather than a warning when _start wasn't defined.
- global entry stubs were not built if they were the only type of
  stub in an executable.

Alan Modra 2dc0e7b400 Don't include sys/param.h
sys/param.h on recent versions of powerpc glibc ends up including
asm/elf.h via asm/sigcontex.h.  asm/elf.h defines R_PPC_* and R_PPC64_*
macros, which clash with our include/elf/ppc.h and include/elf/ppc64.h.
It turns out that no current source uses LD_PATHMAX, so there is no
need for limits.h or sys/param.h, except for one occurrence of UINT_MAX.
I don't have a quarrel with limits.h, but it seems unnecessary just
for UINT_MAX.

Alan Modra caa4096e84 Don't call bfd_link_hash_table_free
Freeing the linker hash table is a royal pain.  It can't be freed
before the _bfd_write_contents call in bfd_close, because some target
bfd_write_contents functions access the hash table.  It can't be freed
after bfd_close either, since bfd_alloc memory holding side data
structures disappears (PR17047).  Clearly the only place it can be freed
is actually in bfd_close.  This patch doesn't do that, but kills off
the existing means of freeing the hash table via a bfd target xvec call.

Joel Brobecker 270c993744 Make it easy to make --disable-werror the default for both binutils and gdb
The goal of this patch is to provide an easy way to make
--disable-werror the default when building binutils, or the parts
of binutils that need to get built when building GDB. In development
mode, we want to continue making -Werror the default with GCC.
But, when making releases, I think we want to make it as easy as
possible for regular users to successfully build from sources.

GDB already has this kind of feature to turn -Werror as well as
the use of the libmcheck library. As GDB Release Manager, I take
advantage of it to turn those off after having cut the branch.
I'd like to be able to do the same for the binutils bits. And
perhaps Tristan will want to do the same for his releases too
(not sure, binutils builders might be a little savvier than GDB
builders).

This patch introduces a new file, called development.sh, which
just sets a variable called $development. In our development branches
(Eg. "master"), it's set to true. But setting it to false would allow
us to change the default behavior of various development-related
features to be turned off; in this case, it turns off the use of
-Werror by default (use --enable-werror to turn it back on).

bfd/ChangeLog:

        * development.sh: New file.
        * warning.m4 (AM_BINUTILS_WARNINGS): Source bfd/development.sh.
        Make -Werror the default with GCC only if DEVELOPMENT is true.

Tested on x86_64-linux by building two ways: One with DEVELOPMENT
set to true, and one with DEVELOPMENT set to false. In the first
case, I could see the use of -Werror, while it disappeared in
the second case.

Alan Modra 397998fc32 Support fusion for ELFv2 stubs
Power8 fuses addis,addi and addis,ld sequences when the target of the
addis is the same as the addi/ld.  Thus
    addis r12,r2,xxx@ha
    addi r12,r12,xxx@l / ld r12,xxx@l(r12)
is faster than
