4d1c633545 ld: Lookup section in output with the same name
When there are more than one input sections with the same section name,
SECNAME, linker picks the first one to define __start_SECNAME and
__stop_SECNAME symbols.  When the first input section is removed by
comdat group, we need to check if there is still an output section
with section name SECNAME.

	PR ld/23591
	* ldlang.c (undef_start_stop): Lookup section in output with
	the same name.

90c745dc54 x86: Don't mask out the GNU_PROPERTY_X86_UINT32_VALID bit
Since only the GNU_PROPERTY_X86_UINT32_VALID bit may be set in data-only
relocatable objects which don't contain any instructions, linker
shouldn't mask out the GNU_PROPERTY_X86_UINT32_VALID bit when merging
GNU_PROPERTY_X86_XXX bits.  Otherwise, linker output doesn't contain
GNU_PROPERTY_X86_XXX property with any data-only relocatable inputs.
This patch keeps the GNU_PROPERTY_X86_UINT32_VALID bit and updates
readelf to print "<None>" if GNU_PROPERTY_X86_XXX property only has
the GNU_PROPERTY_X86_UINT32_VALID bit.

3d9c8f6b3f Delay evaluation of alignment expressions in output sections
git commit 702d16713 broke expressions using CONSTANT(COMMONPAGESIZE)
in ALIGN or SUBALIGN of output section statements, because these
optional fields were evaluated at script parse time and the patch in
question delayed setting of config.commonpagesize.  The right thing to
do is keep the tree representation of those fields for later
evaluation.

a9eafb08b3 x86: Update GNU_PROPERTY_X86_XXX macros
This patch updates GNU_PROPERTY_X86_XXX macros:

1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_AND_LO      0xc0000002
 #define GNU_PROPERTY_X86_UINT32_AND_HI      0xc0007fff

2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_OR_LO    0xc0008000
 #define GNU_PROPERTY_X86_UINT32_OR_HI    0xc000ffff

3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_OR_AND_LO   0xc0010000
 #define GNU_PROPERTY_X86_UINT32_OR_AND_HI   0xc0017fff

4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.

GNU_PROPERTY_X86_FEATURE_1_AND is unchanged.  GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined.  The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX.

772758ac42 ehdr_start twiddles
We force __ehdr_start to defined in before_allocation, then restore
the type and a union after dynamic symbols have been allocated.
The union contains a number of structs, all starting with a "next"
pointer, and various fields depending on the symbol type.  The old
code restored the entire union, but it isn't necessary to restore the
"next" pointer, and in fact it could be wrong if __ehdr_start happened
to be last on the list and some symbols were added before restoring.

	* emultempl/elf32.em (before_allocation): Don't restore
	__ehdr_start u.*.next pointer.

When glibc is enabled with the new GNU_PROPERTY_X86_XXX bits:

BFD will issue an unknown GNU property warning like

f7309df20c x86: Properly merge GNU_PROPERTY_X86_ISA_1_USED
Without the GNU_PROPERTY_X86_ISA_1_USED property, all ISAs may be used.
If a bit in the GNU_PROPERTY_X86_ISA_1_USED property is unset, the
corresponding x86 instruction set isn’t used.  When merging properties
from 2 input files and one input file doesn't have the
GNU_PROPERTY_X86_ISA_1_USED property, the output file shouldn't have
it neither.  This patch removes the GNU_PROPERTY_X86_ISA_1_USED
property if an input file doesn't have it.

This patch replaces the GNU_PROPERTY_X86_ISA_1_USED property with the
GNU_PROPERTY_X86_ISA_1_NEEDED property which is the minimum ISA
requirement.

df136d64fa PowerPC64 EH info for _notoc linkage stubs
This patch generates EH info for the new _notoc linkage stubs, to
support unwinding from asynchronous signal handlers.  Unwinding
through the __tls_get_addr_opt stub was already supported, but that
was just a single stub.  With multiple stubs the EH opcodes need to be
emitted and sized when iterating over stubs, so this is done when
emitting and sizing the stub code.  Emitting the CIEs and FDEs is done
when sizing the stubs, as we did before in order to have the linker
generated FDEs indexed in .eh_frame_hdr.  I moved the final tweaks to
FDEs from ppc64_elf_finish_dynamic_sections to ppc64_elf_build_stubs
simply because it's tidier to be done with them at that point.

05d0e962f0 R_PPC64_REL24_NOTOC support
R_PPC64_REL24_NOTOC is used on calls like "bl foo@notoc" to tell the
linker that linkage stubs for PLT calls or long branches can't use r2
for pic addressing.  Instead, new stubs that generate pc-relative
addresses are used.  One complication is that pc-relative offsets to
the PLT may need to be 64-bit in large programs, in contrast to the
toc-relative addressing used by older PLT linkage stubs where a 32-bit
offset is sufficient until the PLT itself exceeds 2G in size.

.eh_frame info to cover the _notoc stubs is yet to be implemented.

3f6ff4799b Lose _r2off in powerpc64 stub names
Not a lot is conveyed by putting _r2off in a stub symbol that can't be
seen by inspecting the stub code or the toc restoring instruction
immediately after a call via such a stub.  Also, we don't distinguish
plt_call stub symbols from plt_call_r2save stub symbols, so this patch
makes long branch and plt branch stub symbols consistent with that
decision.

a67ae9b01a Re: PowerPC64 __tls_get_addr_opt stub .eh_frame fix
The modified test failed on some powerpc targets due to differences in
default hash style.  If the default hash style is both, then more
sections are created, bumping section ids.  Section id is used in stub
symbols and although the test is careful to not depend on id in
labels, the stub hash traversal order changes when stub names change.
That lead to the stubs being emitted in a different order and thus not
matching expected output.

b8891f8d62 Add support for the C_SKY series of processors.
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants.  V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc.  There is support for bare-metal ELF targets and Linux with both glibc and uClibc.

This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics.  C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers.  (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

33cb30a1f9 Implement PowerPC64 .localentry for value 1
This adds support for ".localentry 1", a new st_other
STO_PPC64_LOCAL_MASK encoding that signifies a function with a single
entry point like ".localentry 0", but unlike a ".localentry 0"
function does not preserve r2.

include/
	* elf/ppc64.h: Specify byte offset to local entry for values
	of two to six in STO_PPC64_LOCAL_MASK.  Clarify r2 return
	value for such functions when entering via global entry point.
	Specify meaning of a value of one in STO_PPC64_LOCAL_MASK.
bfd/
	* elf64-ppc.c (ppc64_elf_size_stubs): Use a ppc_stub_long_branch_r2off
	for calls to symbols with STO_PPC64_LOCAL_MASK bits set to 1.
gas/
	* config/tc-ppc.c (ppc_elf_localentry): Allow .localentry values
	of 1 and 7 to directly set value into STO_PPC64_LOCAL_MASK bits.
ld/testsuite/
	* ld-powerpc/elfv2.s: Add .localentry f5,1 testcase.
	* ld-powerpc/elfv2exe.d: Update.
	* ld-powerpc/elfv2so.d: Update.

491993044b Enhance powerpc ld -r --relax
One of the ill effects of ld -r is to mash together sections.  That
can result in reduced icache performance at runtime due to unexpected
movement of code.  Another problem is that sections can become too
large to link on targets that have limited relative addressing.  ld -r
--relax attempts to overcome the large section problem for branches by
inserting trampolines, but the powerpc support added lots of
unnecessary trampolines.  This patch trims them somewhat.

bfd/
	* elf32-ppc.c (ppc_elf_relax_section): Ignore common or undef locals.
	Avoid trashing toff with added when used as a symbol index.
	Ignore R_PPC_PLTREL24 addends in unused example code.  Avoid
	creating unnecessary fixups when relocatable.
ld/
	* testsuite/ld-powerpc/big.s: New file.
	* testsuite/ld-powerpc/relaxrl.d: New test.
	* testsuite/ld-powerpc/powerpc.exp: Run new test.
	* testsuite/ld-powerpc/relaxr.d: Adjust.
