2376f038d1 Initialize GOT slot for local symbol in non-PIC link.
On ARM/VxWorks 7, the R_ARM_TARGET2 relocation used for exception handling
is R_ARM_GOT_PREL; moreover in Ada you can define local exceptions. In this
case, you may end up with a GOT relocation against a local symbol in a
non-PIC link and the ARM linker leaves the GOT slot uninitialized, unlike
for example the i386 or the SPARC linkers in the same situation.

	* elf32-arm.c (elf32_arm_final_link_relocate) <R_ARM_GOT32>: Small
	cleanup for the case of a global symbol that binds locally.  Also
	install a value in the GOT slot in the case of a local symbol in
	a non-PIC link.

0ee6c332f3 Rename some frame unwind function parameters
I am currently working with these functions, and though this renaming
could help to reason about the code.  Some functions take a frame and
will return the value associated to that frame, others will return the
value associated to the previous frame.  Those usually conveniently
contain "unwind" in their name, but naming the variable next_frame
instead of frame helps remembering which frame we are dealing with.

I also included a little typo fix at the top of frame.h.

d5f4da5e33 ld: Discard .rel.* and .rela.* sections
On many targets, like x86, .rel.dyn/.rela.dyn section is combined from
different .rel/.rela sections by -z combreloc.  To discard dynamic
relocation section, we need to discard .rel.* and .rela.* sections
instead of .rel.dyn and .rela.dyn sections.

Note: This test fails for targets which issue a warning when dynamic
section is discarded.

241e64e3b4 x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if needed
When -z separate-code, which is enabled by default for Linux/x86, is
used to create executable, ld won't place any data in the code-only
PT_LOAD segment.  If there are no data sections placed before the
code-only PT_LOAD segment, the program headers won't be mapped into
any PT_LOAD segment.  When the executable tries to access it (based
on the program header address passed in AT_PHDR), it will lead to
segfault.  This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if
there may be no data sections before the text section so that the
first PT_LOAD segment won't be code-only and will contain the program
header.

Testcases are adjusted to either pass "-z noseparate-code" to ld or
discard the .note.gnu.property section.  A Linux/x86 run-time test is
added.

804d27291b Convert the DWARF reader to new-style buildysm
This converts the DWARF reader to use the new-style buildsym API.  A
new buildsym_compunit is created for each CU and is used to construct
the symbol table.  In some cases the CU must be passed to functions
which previously did not accept it.  FWIW I tend to think that most
methods in the DWARF reader ought to be methods on the dwarf2_cu
object.

0baae8dbd3 Introduce buildsym-legacy.h
This introduces a new header, buildsym-legacy.h, and changes all the
symbol readers to use it.  The idea is to put the function-based
interface, that relies on the buildsym_compunit global, into a
separate header.  Then when a symbol reader is updated to use the new
interface, it can simply not include buildsym-legacy.h, so it's easy
to be sure that the new API is used everywhere.

a60f3166aa Move the context stack to buildsym_compunit
This moves the context stack globals to be members of
buildsym_compunit, changing the type to a std::vector in the process.

Because the callers expect the context stack object to be valid after
being popped, at Simon's suggestion I've changed pop_context to return
the object rather than the pointer.

56ba65a047 Make the Rust parser pure
This makes the Rust parser a pure parser and removes all the
(non-constant) globals from rust-exp.y.  This seemed like a nice
simplification to me and I think it should probably be applied to all
the parsers.  Perhaps it would be good to go even one step farther and
have all parsers derive from parser_state.

3ba174474d [PATCH, LD, AArch64] Fix ifunc testisms
This patch fixes some ifunc testisms after H.J. Lu's patch to enable the
use of IFUNC pointers in position dependent code for binutils. See PR
LD/23169 in binutils bugzilla.

The aarch64 ifunc error message test was changed to no longer expect
this error message as this is now an accepted combination. This patch
also disables the executable tests added by H.J. Lu for aarch64, just as
Alan Modra did with his patch, as these tests only seem to work on some
architectures.

db841b6fcd MIPS/LD: Fix crashing with a discarded dynamic relocation section
Fix a crash that occurs in `_bfd_mips_elf_finish_dynamic_sections' if a
dynamic relocation section has been created, but marked to be discarded
by an assignment to the /DISCARD/ output section in a linker script.
In that case the output section is the absolute section, which has no
ELF section data attached, so trying to set its `sh_size' parameter
causes a null pointer dereference.

This is only done as the value for the DT_RELSZ dynamic entry is being
set, so fix the problem by not creating DT_REL, DT_RELSZ or DT_RELENT
dynamic entries in the first place if the dynamic relocation section
will not be output, as with no dynamic relocation data present these
would not serve their purpose anyway.

Add a generic ELF test case to verify that no dynamic relocation data is
reported in the dynamic segment.

	bfd/
	* elfxx-mips.c (_bfd_mips_elf_size_dynamic_sections): Do not
	create DT_REL, DT_RELSZ or DT_RELENT dynamic entries if the
	dynamic relocation section will be discarded from output.

	the dynamic relocation section will be retained in output.

0458ca4440 Specify architecture for SPARC gas tests
A couple of SPARC gas tests FAIL on Solaris/SPARC (both
sparc-sun-solaris2.11 and sparcv9-sun-solaris2.11):

FAIL: sparc PAUSE
FAIL: sparc CBCOND
FAIL: sparc CFR
FAIL: sparc CRYPTO
FAIL: sparc HPC+VIS3
FAIL: sparc IMA
FAIL: sparc OSA2015 %mwait asr and MWAIT instruction
FAIL: sparc OSA2015 %mcdper asr
FAIL: sparc SPARC5 and VIS4.0
FAIL: OSA2015 crypto instructions
FAIL: SPARC6
FAIL: FPCMPSHL OSA2017 instructions
FAIL: OSA2017 ONADD/ONSUB/ONMUL/ONDIV instructions.
FAIL: OSA2017 RLE instructions
FAIL: sparc64 rdasr
FAIL: sparc64 rdpr
FAIL: sparc64 rdhpr
FAIL: sparc64 wrasr
FAIL: sparc64 wrpr

It turns out there's a common pattern here: failures happen for all
tests that use SPARC ISA extensions beyond sparcv9, e.g. for the sparc
PAUSE test:

regexp_diff match failure
regexp "^   0:  b7 80 40 02     wr  %g1, %g2, %pause$"
line   "   0:   b7 80 40 02     wr  %g1, %g2, %asr27"
[...]
regexp_diff match failure
regexp "^   8:  b7 80 20 08     pause  8$"
line   "   8:   b7 80 20 08     wr  8, %asr27"
[...]

The fix is easy, actually: just as the tests specify the ISA extension
to use as a gas flag, the same needs to be done for objdump.  For the
test above, which has -Av9v, this means passing -msparc:v9v to objdump.
Doing so makes all but two (unrelated; to be reported separately)
failures go away.

This doesn't happen on Linux/SPARC, where gas emits GNU object attributes
matching the hardcare capabilities used.  Since gas doesn't yet implement
Solaris-style object capabilites, the explicit -march is needed, but only
passed on Solaris.

Tested on both sparc-sun-solaris2.11 and sparcv9-sun-solaris2.11.

	* testsuite/gas/sparc/sparc.exp (set_tests_arch): New proc.
	Prefix v9c, v9d, v9v, v9m, v9m8 tests with corresponding
