0e1862bb40 Add output_type to bfd_link_info
The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs.  This
patch adds an "output_type" field:

enum output_type
{
  type_unknown = 0,
  type_executable,
  type_dll,
  type_relocatable
};

and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC.  Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.

8efa2874ab Issue an error for read-only segment with dynamic IFUNC relocations
To load an ELF binary with DT_TEXTREL tag, the dynamic linker calls
__mprotect on the read-only segment with PROT_READ|PROT_WRITE before
applying dynamic relocation.  It leads to segfault when performing
IFUNC relocations since the read-only segment has no execute permission.
This patch changes x86 linker to issue an error for read-only segment
with dynamic IFUNC relocations.  Other backends with IFUNC support
may need a similar change.

13a2df29c9 Set EI_OSABI to ELFOSABI_GNU for local IFUNC symbols
Since the backend elf_add_symbol_hook isn't called on local symbols,
the EI_OSABI field isn't to ELFOSABI_GNU where are local IFUNC symbols.
This patch changes the x86 backends to set has_gnu_symbols if there are
relocations against IFUNC symbols.  Other backends with IFUNC support
may need a similar change.

This patch also changes the type of has_gnu_symbols from bfd_boolean to
enum elf_gnu_symbols.

87ad46af87 [AArch64] Fix test failures on elf configuration
This patch fixed those failures on elf configuration by:

   * Improve the ILP32 target selector "aarch64_choose_ilp32_emul",
     makes it more robust. Target triples copied from configure.tgt

   * Updated emit-relocs-86/-overflow.d to use aarch64_choose_ilp32_emul
     which is following what have done with emit-relocs-28.

   * Those instruction encoding mismatch is because those encoding
     contains pc-relative address. As for elf, we may have different
     start address. relaxed encodind check, especially for
     aarch64-farcall-b/bl-plt, as the main purpose of those check are
     ELF text/data layout, we just want to make sure veneer to plt stub
     is generated.

9c98104c4c ld: map option for run_dump_test requires no program.
When using run_dump_test with the map option to compare the linker map

program can still be given if needed, but leaving it off will no longer
produce an error.

ld/testsuite/ChangeLog:

bb57e4c7bd ld: Add file based error/warning regexp for run_dump_test.
The run_dump_test mechanism supports options error and warning, which
allow regexp to be specified within the test file, these regexp are
matched against the stderr output from the linker.

Similar dump test style functions for gas and gdb also support file
based matching versions of these options; the patterns are placed into a
file which the test driver then references.  It is sometimes clearer,
when the pattern to be matched spans multiple lines if the patterns can
be placed into a separate file.

This patch adds new options error_output and warning_output for the
linker run_dump_test function.  These new options take a filename
parameter, this file is then used (with regexp_diff) to compare against
the linker output.

ld/testsuite/ChangeLog:

	* ld/ld-lib.exp (run_dump_test): Add error_output and
	warning_output options.

0a61824343 ld: Add '--require-defined' command line option.
Add a new command line option '--require-defined' to the linker.  This
option operates identically to the '--undefined' option, except that if
the symbol is not defined in the final output file then the linker will
exit with an error.

When making use of --gc-section, or just when trying to pull in parts of
a library, it is not uncommon for a user to use the '--undefined'
command line option to specify a symbol that the user then expects to be
defined by one of the object files supplied to the link.

However, if for any reason the symbol is not satisfied by an object
provided to the link the user will be left with an undefined symbol in
the output file, instead of a defined symbol.

In some cases the above behaviour is what the user wants, in other cases
though we can do better.  The '--require-defined' option tries to fill
this gap.  The symbol passed to the '--require-defined' option is
treated exactly as if the symbol was passed to '--undefined', however,
before the linker exits a check is made that all symbols passed to
'--require-defined' are actually defined, if any are not then the link
will fail with an error.

ld/ChangeLog:

	* ld.texinfo (Options): Document --require-defined option.
	* ldlang.c (struct require_defined_symbol): New structure.
	(require_defined_symbol_list): New variable.

e77e648e93 Don't set link_info.executable for "ld -r"
This patch changes "ld -r" not to set link_info.executable.  It
removes !info->relocatable check for info->executable and adds it
for !info->executable in elflink.c.

bfd/

	* elflink.c (elf_link_add_object_symbols): Remove
	!info->relocatable check for info->executable.  Add
	!info->relocatable check for !info->executable.
	(elf_link_output_extsym): Remove
	!info->relocatable check for info->executable.

ld/

	* lexsup.c (parse_args): Don't set link_info.executable to
	TRUE for link_info.relocatable.

e5654c0f84 Fallout from "Reorder more powerpc64 sections for -z relro"
Commit 23283c1b changed the layout of some bss style sections on
powerpc64, but neglected to add a page gap before the third PT_LOAD
segment created by this reording.  Without a page gap we get two
PT_LOAD headers that overlap by one page in memory.  That shouldn't be
allowed because the dynamic loader will load garbage from the first
page of the last segment over the last page of the previous segment.

bfd/
	* elf.c (_bfd_elf_map_sections_to_segments): Do not make a new
	segment for loaded sections after nonloaded sections if the
	sections are on the same page.

6f8ea6c424 Set NOPIE_CFLAGS and NOPIE_LDFLAGS
GCC 6 can be configured to generate PIE by default.  But some linker
size tests expect non-PIE.  This patch defines NOPIE_CFLAGS to
"-fno-PIE" and NOPIE_LDFLAGS to "-no-pie" if target compiler supports
them.  Add $NOPIE_CFLAGS and $NOPIE_LDFLAGS to linker size tests if
needed.

	* config/default.exp (NOPIE_CFLAGS): New.
	(NOPIE_LDFLAGS): Likewise.
	* ld-size/size.exp (run_cc_link_tests): Add $NOPIE_CFLAGS and
	$NOPIE_LDFLAGS if needed.
	(run_ld_link_exec_tests): Add $NOPIE_CFLAGS if needed.

c45bd4fd43 Check address of versined symbol
Since GCC 5 folds symbol address comparison, assuming each symbol has a
different address, &foo == &bar is always false for GCC 5.  This patch
adds check_ptr_eq if 2 addresses are the same and uses it to check the
address of versined symbol.

	PR ld/18718
	* ld-elf/check-ptr-eq.c: New file.
	* ld-elf/pr18718.c (main): Call check_ptr_eq.
	* ld-elf/shared.exp: Add check-ptr-eq.c to PR ld/18718 tests.
