Alan Modra 2300b5a141 Add gcc-4.9 libgomp symbols requiring --plt-thread-safe for power7
powerpc64 ld builds plt call stubs with a read barrier to provide
thread safety on lazy plt updates, necessary on multi-threaded apps
with power7 or later weakly ordered memory.  gcc-4.9 libgomp
introduced more functions that could call pthread_create, which means
we have more functions that if referenced in an executable should
cause a default of --plt-thread-safe.

Alan Modra b53dfeb26e PowerPC64 ELFv1 function symbol definition vs LTO and discarded sections
When functions are emitted in comdat groups, global symbols defined in
duplicates of the group are treated as if they were undefined.  That
prevents the symbols in the discarded sections from affecting the
linker's global symbol hash table or causing duplicate symbol errors.
Annoyingly, when gcc emits a function to a comdat group, it does not
put *all* of a function's code and data in the comdat group.
Typically, constant tables, exception handling info, and debug info
are emitted to normal sections outside of the group, which is a
perennial source of linker problems due to the special handling needed
to deal with the extra-group pieces that ought to be discarded.  In
the case of powerpc64-gcc, the OPD entry for a function is not put in
the group.  Since the function symbol is defined on the OPD entry this
means we need to handle symbols in .opd specially.

To see how this affects LTO in particular, consider the linker
testcase PR ld/12942 (1).  This testcase links an LTO object file
pr12942a.o with a normal (non-LTO) object pr12942b.o.  Both objects
contain a definition for _Z4testv in a comdat group.  On loading
pr12942a.o, the linker sees a comdat group (actually linkonce section)
for _Z4testv and a weak _Z4testv defined in the IR.  On loading
pr12942b.o, the linker sees the same comdat group, and thus discards
it.  However, _Z4testv is a weak symbol defined in .opd, not part of
the group, so this weak symbol overrides the weak IR symbol.  On
(re)loading the LTO version of pr12942a.o, the linker sees another
weak _Z4testv, but this one does not override the value we have from
pr12942b.o.  The result is a linker complaint about "`_Z4testv'
... defined in discarded section `.group' of tmpdir/pr12942b.o".

	* elf64-ppc.c (ppc64_elf_add_symbol_hook): If function code
	section for function symbols defined in .opd is discarded, let
	the symbol appear to be undefined.
	(opd_entry_value): Ensure the result section is that for the
	function code section in the same object as the OPD entry.

Alan Modra c2aaac080c Discard zero address range eh_frame FDEs
These are useless because they can't match any address.  In fact,
worse than useless because the .eh_frame_hdr lookup table matching
addresses to FDEs does not contain information about the FDE range.
The table is sorted by address;  Range is inferred by the address
delta from one entry to the next.  So if a zero address range FDE is
followed by a normal non-zero range FDE for the same address,
everything is good.  However, the qsort could just as easily sort the
FDEs in the other order, in which case the normal FDE would
effectively be seen to have a zero range.

Markus Trippelsdorf e44f5bef12 BFD: Add support for more than one plugin in lib/bfd-plugins
ar, nm and ranlib currently lack the ability to handle more than one
plugin in lib/bfd-plugins. This patch reshuffles the logic in plugin.c
to add this functionality. One can now place both llvm and gcc plugins
in this directory and have them loaded automatically.
Mixed gcc/llvm archives are also supported (but not very useful until
ld.bfd and ld.gold also would load multiple plugins and use them to
claim different object files).

	attaching its vdso.bin.gz
GDB (FSF HEAD 5e43d46791) regression:
reproducer:
	./gdb -ex start ./gdb
actual result / FAIL:
	Got object file from memory but can't read symbols: File truncated.
expected result / PASS:
	<nothing>
or / PASS:
	warning: Could not load shared library symbols for linux-vdso.so.1.
	Do you need "set solib-search-path" or "set sysroot"?

That "warning: Could not load shared library..." is mostly harmless (it is
a bug in GDB), in the FAIL case it is not printed just because
bfd_check_format() fails there.

It seems logical to me this way when the 'size' parameter has been already
added.
Alan Modra:
I was wrongly thinking that the section headers were
always last when I wrote that code.  (They are now!  If you relink
that vdso with current binutils master you won't hit this problem, but
that of course doesn't help existing kernels.)

I do not see a regression for add-symbol-file-from-memory for libncurses.so.5
from the original thread above.

  Start of section headers:          1080 (bytes into file)
  Size of section headers:           64 (bytes)
  Number of section headers:         13
  Section header string table index: 8
Section Headers:
  [Nr] Name              Type            Address          Off    Size   ES Flg Lk Inf Al
  [ 8] .fake_shstrtab    STRTAB          0000000000000780 000780 000076 00   A  0   0 32
Program Headers:
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align
  LOAD           0x000000 0x0000000000000000 0x0000000000000000 0x0012fe 0x0012fe R E 0x1000

size == 0x2000
shdr_end == 0x778 == 1080 + 13 * 64
high_offset == 0x12fe

       else if (size >= shdr_end)
-	high_offset = shdr_end;
+	high_offset = size;

But then 0x778 < 0x780 for "Section header string table index" so whole
bfd_check_format() fails because section headers were not cleared here:
  /* If the segments visible in memory didn't include the section headers,
     then clear them from the file header.  */
  if (high_offset < shdr_end)

Kuan-Lin Chen 1c8f6a4d1f NDS32: Code refactoring of relaxation.
Refactor each relaxation pattern to raise the maintainability.
In origin, all patterns is analysed in nds32_elf_relax_section,
so it is hard to debug and maintain.  Therefore, we classify all
patterns into different functions in this patch.
Moreover, we adjust all optimizations into nds32_elf_relax_section
to take these optimizations in turn.  This can promise all relaxation
being done after calling gld${EMULATION_NAME}_after_allocation.

Alan Modra ae6c7e33e1 Test for overflow in eh_frame_hdr entries and for overlapping FDEs
With larger binaries on 64-bit systems, or indeed just binaries that
have a large gap between text and data, it is possible for the
.eh_frame_hdr lookup table entry values to overflow a signed 32-bit
relative offset.  It is also a requirement for the glibc FDE lookup
code that only one FDE claim to cover any given address.

Alan Modra a485e98ea0 Move ELF section headers to end of object file
Currently, section ordering differs a little for non-loaded reloc
sections output by ld -emit-relocs or ld -r and that after passing
such objects through objcopy.  Not that it really matters, but it
would be better for a simple objcopy to produce an unchanged output
object file.  Also, section headers are put somewhere in the middle of
the non-loaded sections, again slightly differently for ld and
objcopy.  This patch fixes these discrepancies and puts section
headers last, which is where gold puts them, and is where
bfd_from_remote_memory wrongly assumed they will be found.

Alan Modra 4564fb94da Delete redundant struct cie field
cie->output_sec is used to when merging CIEs to ensure that only CIEs
from the same output section are merged.  I noticed an assignment to
this field in _bfd_elf_parse_eh_frame, and thought "That's wrong,
output_section isn't set properly when _bfd_elf_parse_eh_frame is
called from gc-sections code".  It turns out that this assignment is
premature, and in fact a dead store.  find_merged_cie overwrites with
the correct value before the field is ever used.  On looking a little
more it becomes apparent that cie->cie_inf.u.cie.u.sec->output_section
holds the same value, so cie->output_sec is redundant.

	* elf-eh-frame.c (struct cie): Delete "output_sec" field.
	(cie_eq, cie_compute_hash): Use output_section from cie_inf instead.
2014-08-22 10:09:09 +09:30
Alan Modra da44f4e546 Index PowerPC64 linker generated .eh_frame in .eh_frame_hdr
I noticed recently that .eh_frame FDEs generated by the linker for
call stubs and .glink weren't being indexed in .eh_frame_hdr, due to
bfd_elf_discard_info being run before the linker generated .eh_frame
sections were available for parsing.  This patch moves code around in
elf64-ppc.c and ppc64elf.em to avoid that problem.

Another problem fixed here is that --gc-sections parses .eh_frame
early, and the existing machinery allows only one go at parsing the
.eh_frame sections.  That resulted in the linker generated .eh_frame
CIEs not being merged and no .eh_frame_hdr index entries for those
FDEs.  It turns out that all the info from parsing .eh_frame is
attached to the section, so order of parsing isn't important, and
after parsing sec_info_type being set will prevent a section being
parsed again.  At least, when parsing doesn't hit an error.  So there
isn't really any need for "parsed_eh_frame".  "merge_cies" is also
redundant, which means _bfd_elf_{begin,end}_eh_frame_parsing can also
disappear.

Will Newton 01e6c1a48d ARM: Add support for armeb-*-eabi*
At the moment it is possible to configure binutils for these triples
but the resulting linker defaults to little endian with huge numbers
of testsuite failures, which on the face of it does not appear to make
much sense.

This patch makes the behaviour similar to armeb-elf and the testsuite
is clean.

Alan Modra b879806f2f configury changes to make ld plugin support controlled by --enable-plugins
This also makes --enable-plugins default to on for hosts that can
support plugins, so we have consistent lto toolchain support.  The
ACX_LARGEFILE moves aren't strictly necessary, but are harmless and
will be necessary if plugin support is extended to more hosts via
libtool's dlopen support.  I started down that path then decided it
was more work than I was interested in doing.  (ACX_LARGEFILE invokes
AC_PLUGINS.)

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".

Alan Modra 13e570f80c Fix LTO vs. COFF archives
Avoid scan of symbols on objects in coff archives since we don't need
to do anything special with common symbols.  The scan is quite useless,
and breaks LTO due to slim LTO objects not having symbols available
until after the plugin has claimed them.  Instead we can add objects
based on their archive symbol map.

Also, rip out the archive symbol hash table used by the generic
linker.  Using a hash breaks one feature of unix archive linking;
The first object file in an archive defining any given symbol should
be the object extracted to satisfy that symbol.  What's more a hash
isn't much faster except in pathological cases where object file
ordering causes many scans of the archive.  See the comment which I'm
removing from elf_link_add_archive_symbols.

Finally, tidy elflink.c archive handling a little.

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.

Alan Modra bffebb6ba5 Copy st_other for linker script symbol assignments
This fixes a problem seen on powerpc64le ELFv2 when creating a
function symbol alias with ld --defsym.  st_other needs to be copied
from the source symbol to the alias in order to set up the local entry
offset for the alias.  I decided to make this change in the generic
ELF code rather than in elf64-ppc.c since it looks like other targets
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'.

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 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.

Alan Modra a47622ac1b Allow both signed and unsigned fields in PowerPC cmpli insn
There are legitimate reasons to allow a signed value in a cmpli insn
field, for example to test for a "stw r1,lock@sdarel(r13)" instruction
in user code, a kernel might use
	subis r3,r3,STW_R1_0R13@ha	# subtract off high part
	cmplwi r3,lock@sdarel		# is low part accessing lock?
Since the lock@sdarel may take a range of -32768 to 32767,
the allowed range of cmpli immediate must be at least [-32768,65535].

bfd/
	* elf32-ppc.c (ppc_elf_relocate_section): Treat field of cmpli
	insn as a bitfield; Use complain_overflow_bitfield.

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.
        * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add
        $(srcdir)/development.sh.
        * Makefile.in, configure: Regenerate.

        bfd's development.sh.

        * Makefile.am (CONFIG_STATUS_DEPENDENCIES): Add dependency on
        bfd's development.sh.

gdb/ChangeLog:

        * development.sh: Delete.
        * Makefile.in (config.status): Adjust dependency on development.sh.
        * configure.ac: Adjust development.sh source call.
        * configure: Regenerate.

gdb/gdbserver/ChangeLog:

        * configure.ac: Adjust development.sh source call.
        * Makefile.in (config.status): Adjust dependency on development.sh.
        * configure: Regenerate.

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
    addis r11,r2,xxx@ha
    addi r12,r11,xxx@l / ld r12,xxx@l(r11)

Alan Modra 93d1b056cb Rewrite ppc32 backend .sdata and .sdata2 handling
1) _SDA_BASE_ and _SDA2_BASE_ and defined automatically, in a similar
   manner to the way _GLOBAL_OFFSET_TABLE_ is handled.  It's a little
   more complicated to remove the symbols because _SDA_BASE_ needs to
   be there if either .sdata or .sbss is present, and similarly for
   _SDA2_BASE.
2) The linker created .sdata and .sdata2 sections used for
   R_PPC_EMB_SDAI16 and R_PPC_EMB_SDA2I16 pointers are created early.
   Nowadays we strip unneeded sections from the output, so it isn't
   necessary to delay creating the sections.
3) The output section for targets of various SDA relocs is now checked
   as per the ABI(s).  We previously allowed .sdata.foo and similar,
   most likely because at some stage we were checking input sections.

Also, the patch fixes a long-standing bug in size_input_sections
that affects the values of symbols defined in stripped input
sections.

Hans-Peter Nilsson 1218d67db1 * mmo.c (mmo File layout documentation): Add note about low bits
of address.
	(mmo_write_chunk): When handling data remainder, assert that
	previous remaining data is flushed.
	(mmo_write_loc_chunk): Only look for trailing and leading zeros
	when dealing with an aligned VMA and for aligned lengths.  Don't skip
	the last 32-bit-word of zeros.
	(mmo_write_loc_chunk): Emit an error if the VMA is not aligned.
	(mmo_scan) <case LOP_QUOTE>: Move re-alignment of vma before
	emitting data, not after updating it.
	<case LOP_LOC>: Call mmo_decide_section with aligned vma.

Nick Clifton a953eec996 Fixes a problem with the BFD library running out of memory because it mistakenly
thought that an uncompressed .debug_str section was compressed.

	* compress.c (bfd_is_section_compressed): When checking the
	.debug_str section, also check the fifth byte in the section is
	not part of a string.

	* binutils-all/debug_str.s: New test.
	* binutils-all/debug_str.d: New test control file.
	* binutils-all/compress.exp: Run debug_str test.

Alan Modra 5087d52931 Don't use vma to identify eh_frame personality function
This is all we should need to be able to run the eh_frame parts of
bfd_elf_discard_info before bfd_elf_size_dynamic_sections

	* elf-eh-frame.c (struct cie.personality): Replace val with sym.
	(find_merged_cie): Identify personality functions by (bfd_id,index)
	pair when a local sym is used.

Christian Svensson 230977a4a5 or1k: Do not override section for non-TLS symbols.
Outgoing section for relocations was computed by setting a shared
pointer to which section should be used. For TLS this was overriden to
use .rela.got since they use GOT entries but since the pointer is per
section that whole section was relocated to .rela.got, even non-TLS
relocations.

* elf32-or1k.c: Fix a bug where non-TLS relocations would be forced
into .rela.got if it contained TLS relocations as well.

Nick Clifton 88667baf24 This fixes a compile time warning which is being treated as an error. Older
versions of gcc complain about part of a conditional expression always
evaluating to false because of the size of the operands involved, even when
the entire expression is already known to be false.

	* peXXigen.c (_bfd_XXi_swap_sym_out): Another fix for building on
	a 342-bit host.  This time for older versions of gcc.
