68b007788a ld/x86: Add -z report-relative-reloc
Linker generated relative relocations don't have symbol info:

[hjl@gnu-cfl-2 tmpdir]$ readelf -rW dump

Relocation section '.rela.dyn' at offset 0x180 contains 2 entries:
 Offset     Info    Type                Sym. Value  Symbol's Name + Addend
00002f70  00000008 R_X86_64_RELATIVE                 1000
00002f68  00000025 R_X86_64_IRELATIVE                1007
[hjl@gnu-cfl-2 tmpdir]$

Add -z report-relative-reloc to x86 ELF linker to report dynamic relative
relocations:

[hjl@gnu-cfl-2 tmpdir]$ ../ld-new -pie -melf32_x86_64 -z report-relative-reloc -o dump report-reloc-1.o
dump: R_X86_64_IRELATIVE (offset: 0x00002f68, info: 0x00000025, addend: 0x00001007) against 'ifunc' for section '.data.rel.ro.local' in report-reloc-1.o
dump: R_X86_64_RELATIVE (offset: 0x00002f70, info: 0x00000008, addend: 0x00001000) against '_start' for section '.data.rel.ro.local' in report-reloc-1.o
[hjl@gnu-cfl-2 tmpdir]$

It can be used to map relative relocations to corresponding symbols.

d1bcae833b ELF: Don't generate unused section symbols
For ELF targets, section symbols are required only for relocations.
With -ffunction-sections -fdata-sections, there can be many unused
section symbols.  Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are

With unused section symbols   : 39411698 bytes
Without unused section symbols: 39227002 bytes

The unused section symbols in libstdc++.a occupy more than 180 KB.

Add BSF_SECTION_SYM_USED to indicate if a section symbol should be
included in the symbol table.  The BSF_SECTION_SYM_USED should be set
if the section symbol is used for relocation or the section symbol is
always included in the symbol table.

Add keep_unused_section_symbols to bfd_target to indicate if unused
section symbols should be kept.  If TARGET_KEEP_UNUSED_SECTION_SYMBOLS
is defined as FALSE, unused ection symbols will be removed.

Tested on Linux/x86.  Other ELF backends need to:

1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE.
2. Mark used section symbols in assembler backend.
3. Remove unused section symbols from expected assembler and linker
outputs.

0fa0fc8539 x86: Ignore CS/DS/ES/SS segment-override prefixes in 64-bit mode
"In 64-bit mode, the CS, DS, ES, and SS segment-override prefixes have
no effect. These four prefixes are not treated as segment-override
prefixes for the purposes of multiple-prefix rules. Instead, they are
treated as null prefixes." (AMD APM v2).

However, objdump disassembles instructions containing those ignored
prefixes by still generating that segment override:

  66 66 2e 0f 1f 84 00 	data16 nopw %cs:0x0(%rax,%rax,1)
  00 00 00 00

Print those segment override prefixes as excessive ones:

  66 66 2e 0f 1f 84 00    data16 cs nopw 0x0(%rax,%rax,1)
  00 00 00 00

which is what they actually are - they have no effect and the decoding
hardware ignores them.

b0ab069373 x86: Support GNU_PROPERTY_X86_ISA_1_BASELINE marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250

X86 ISA markers are updated:

https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13

GNU_PROPERTY_X86_ISA_1_BASELINE is added and GNU_PROPERTY_X86_ISA_1_V[234]
are updated:

 #define GNU_PROPERTY_X86_ISA_1_BASELINE (1U << 0)
 #define GNU_PROPERTY_X86_ISA_1_V2       (1U << 1)
 #define GNU_PROPERTY_X86_ISA_1_V3       (1U << 2)
 #define GNU_PROPERTY_X86_ISA_1_V4       (1U << 3)

32930e4edb x86: Support GNU_PROPERTY_X86_ISA_1_V[234] marker
GCC 11 supports -march=x86-64-v[234] to enable x86 micro-architecture ISA
levels:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97250

Update GNU_PROPERTY_X86_ISA_1_XXX macros:

https://gitlab.com/x86-psABIs/x86-64-ABI/-/merge_requests/13

in x86 ELF binaries to indicate that micro-architecture ISA levels
required to execute the binary:

 #define GNU_PROPERTY_X86_ISA_1_NEEDED (GNU_PROPERTY_X86_UINT32_OR_LO + 2)
 #define GNU_PROPERTY_X86_ISA_1_USED (GNU_PROPERTY_X86_UINT32_OR_AND_LO + 2)
 #define GNU_PROPERTY_X86_ISA_1_V2 (1U << 0)
 #define GNU_PROPERTY_X86_ISA_1_V3 (1U << 1)
 #define GNU_PROPERTY_X86_ISA_1_V4 (1U << 2)

The previous GNU_PROPERTY_X86_ISA_1_XXX  macros are deprecated and renamed
to GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.

In addition to EM_X86_64, GNU_PROPERTY_X86_ISA_1_V[234] marker can be used
by ld.so to detect the x86-64-v4 shared library placed in an x86-64-v2
directory by mistake on an x86-64-v2 machine to avoid crashes on x86-64-v4
instructions.

Add -z x86-64-v[234] linker command line option to mark x86-64-v[234]
ISA level as needed.

Also add

 #define GNU_PROPERTY_X86_FEATURE_2_MASK (1U << 11)

for mask registers.

36068e2fa5 elf/x86-64: Adjust relocation for PE/x86-64 inputs
PE linker calls _bfd_relocate_contents to resolve relocation, instead of
bfd_perform_relocation.  But ELF linker calls bfd_perform_relocation, not
_bfd_relocate_contents.  When linking PE/x86-64 inputs to generate ELF
output, we need to adjust PE/x86-64 relocations in bfd_perform_relocation.

Enable PE/x86-64 in bfd together with PEI/x86-64.  Update run_ld_link_tests
to handle bzip2 binary inputs.

36938cabf0 x86: avoid attaching suffixes to unambiguous insns
"Unambiguous" is is in particular taking as reference the assembler,
which also accepts certain insns - despite them allowing for varying
operand size, and hence in principle being ambiguous - without any
suffix. For example, from the very beginning of the life of x86-64 I had
trouble understanding why a plain and simple RET had to be printed as
RETQ. In case someone really used the 16-bit form, RETW disambiguates
the two quite fine.

348fe36b1d Remove perror from ld_assemble, ld_compile and ld_nm
ERROR should really be reserved for errors in the testsuite framework,
not just normal errors from the tools under test.  Removing use of
perror has been suggested before but without action, over concerns
that some test failures might be missed.  This patch removes uses of
perror in ld_assemble, ld_compile and ld_nm, and updates numerous
places that ignored the result of these functions by inappropriately
returning an "unresolved" test status.  Net result over my large set
of targets look good, in some cases improving the diagnostics, eg:

i386-msdos  -ERROR: tmpdir/script: nm failed
i386-msdos  -ERROR: tmpdir/script: nm failed
i386-msdos  -ERROR: tmpdir/script: nm failed
i386-msdos  -ERROR: tmpdir/script: nm failed

a8c4d40b57 ELF: Add support for unique section ID to assembler
Clang's integrated assembler supports multiple section with the same
name:

	.section .text,"ax",@progbits,unique,1
	nop
	.section .text,"ax",@progbits,unique,2
	nop

"unique,N" assigns the number, N, as the section ID, to a section.  The
valid values of the section ID are between 0 and 4294967295.  It can be
used to distinguish different sections with the same section name.

This is useful with -fno-unique-section-names -ffunction-sections.
-ffunction-sections by default generates .text.foo, .text.bar, etc.
Using the same string can save lots of space in .strtab.

This patch adds section_id to bfd_section and reuses the linker
internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler
internal use to mark valid section_id.  It also updates objdump to
compare section pointers if 2 sections comes from the same file since
2 different sections can have the same section name.

14470f0755 x86-64: Fix TLSDESC relaxation for x32
For x32, we must encode "lea x@TLSDESC(%rip), %reg" with a REX prefix
even if it isn't required.  Otherwise linker can’t safely perform
GDesc -> IE/LE optimization.  X32 TLSDESC sequences can be:

40 8d 05 00 00 00 00	rex lea	x@TLSDESC(%rip), %reg
...
67 ff 10		call	*x@TLSCALL(%eax)

or the same sequence as LP64:

48 8d 05 00 00 00 00	lea	foo@TLSDESC(%rip), %reg
...
ff 10			call	*foo@TLSCALL(%rax)

We need to support both sequences for x32.  For both GDesc -> IE/LE
transitions,

67 ff 10		call	*x@TLSCALL(%eax)

should relaxed to

0f 1f 00		nopl	(%rax)

For GDesc -> LE transition,

40 8d 05 00 00 00 00	rex lea	x@TLSDESC(%rip), %reg

should relaxed to

40 c7 c0 fc ff ff ff	rex movl $x@tpoff, %reg

For GDesc -> IE transition,

40 8d 05 00 00 00 00	rex lea	x@TLSDESC(%rip), %reg

should relaxed to

40 8b 05 00 00 00 00	rex movl x@gottpoff(%rip), %eax

660df28acf Prefer object over notype symbols when disassembling
Changing objdump disassembly output like this always requires some
testsuite changes, with the avr and x64_64 changes simply due to
picking up better symbols, the whole point of the patch.

The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols
to STT_OBJECT, which objdump now chooses in preference to script
symbols.  The problem is that objdump looks at the first symbol in the
section being disassembled, and if object type, just dumps out bytes
rather than disassembling.  This results in new failures:

FAIL: JAL overflow 2
FAIL: undefined weak symbol overflow
FAIL: undefined weak symbol overflow (n32)
FAIL: undefined weak symbol overflow (n64)

So for mips-sgi-irix function symbols really do need to be function
type.  I fixed a few more than just the required minimum to avoid the
above test fails.

44ed80923a Use better test for usable compiler in ld testsuite.
The ld testsuite includes numerous tests that depend on being able to
compile and link programs with the C compiler.  Some of these tests
use [which $CC] to check for the presence of the compiler before
proceeding with the test, but run_ld_link_exec_tests and run_cc_link_tests
give ERRORs if compilation fails.  Also, even if $CC is defined and present,
it may not be usable due to missing libraries, etc.

This patch adds a new procedure check_compiler_available that attempts
to build an empty program and caches the result.  Uses of [which $CC]
are replaced with calls to this procedure, and run_ld_link_exec_tests
and run_cc_link_tests now also guard attempts to use $CC.

44b27f959a x86: Properly set IBT and SHSTK properties for -z ibt/shstk
There should be no AND properties if some input doesn't have them.  We
should set IBT and SHSTK properties for -z ibt and -z shstk if needed.

83924b3846 x86-64: Restore PIC check for PCREL reloc against protected symbol
commit bd7ab16b45
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Tue Feb 13 07:34:22 2018 -0800

    x86-64: Generate branch with PLT32 relocation

removed check R_X86_64_PC32 relocation against protected symbols in
shared objects.  Since elf_x86_64_check_relocs is called after we
have seen all input files, we can check for PC-relative relocations in
elf_x86_64_check_relocs.  We should not allow PC-relative relocations
against protected symbols since address of protected function and
location of protected data may not be in the shared object.

	* elf64-x86-64.c (elf_x86_64_need_pic): Check
	SYMBOL_DEFINED_NON_SHARED_P instead of def_regular.
