95abb3944c [binutils] Fix printing of .debug_str_offsets 
With exec:

$ clang -gdwarf-5 ./src/gdb/testsuite/gdb.dwarf2/fission-mix*.c
...
we have:
...
$ readelf -w a.out
  ...
Contents of the .debug_str_offsets section:

The section consists of two parts, one for each CU, each with a header, but
the printing only reads the first header as a header, and prints the second
header as:

d60f79984a [binutils] Print DWO ID 
With exec:
...
$ gcc -gsplit-dwarf ~/hello.c -gdwarf-5
...
a dwarf-5 DW_UT_skeleton CU is generated, but the corresponding DWO ID is not
printed by readelf -wi.

Add this, such that we have:

d9d9d8ef8c [binutils] Handle absolute DW_AT_dwo_name 
With an exec:
...
$ pwd
/home/vries/tmp
$ gcc /home/vries/tmp/src/hello.c -gsplit-dwarf -c \
  -o /home/vries/tmp/obj/hello.o
...
I get:
...
$ readelf -w obj/hello.o > READELF
readelf: Warning: Unable to load dwo file: \
  /home/vries/tmp//home/vries/tmp/obj/hello.dwo
...

The dwo file name is listed here:
...
    <20>   DW_AT_GNU_dwo_name: /home/vries/tmp/obj/hello.dwo
    <24>   DW_AT_comp_dir    : /home/vries/tmp
...

The standard states about the DW_AT_dwo_name attribute:
...
value is a null-terminated string containing the full or relative path name
(relative to the value of the DW_AT_comp_dir attribute, see below) of the
object file that contains the full compilation unit.
...

So, readelf shouldn't try to prefix an absolute path with DW_AT_comp_dir.

Fix this in load_dwo_file by handling the absolute path case.

binutils/ChangeLog:

2021-02-10  Tom de Vries  <tdevries@suse.de>

	PR binutils/27391
	* dwarf.c (load_dwo_file): Handle case that name is absolute path.

52ff20fe7b [binutils] Handle presence of both .debug_ranges and .debug_rnglists 
With exec:
...
$ g++ src/gdb/testsuite/gdb.cp/cpexprs.cc -gdwarf-5 -fdebug-types-section
...
I run into:
...
$ readelf -w a.out > READELF
readelf: Error: Invalid range list entry type 126
readelf: Error: Invalid range list entry type 60
...

The executable contains both a .debug_rnglists section (for CU
cpexprs.cc) and a .debug_ranges section (for other CUs, like crti.S).  But
when executing display_debug_ranges for say, section .debug_rnglists it also
tries to use the range list references related to section .debug_ranges.

Fix this by filtering out the .debug_range references when handling
.debug_rnglists and vice versa.

binutils/ChangeLog:

2021-02-10  Tom de Vries  <tdevries@suse.de>

	PR binutils/27371
	* dwarf.c (display_debug_ranges): Filter range lists according to
	section.

5f128a25f2 [binutils] Handle DW_FORM_ref_sig8 in get_type_abbrev_from_form 
When compiling an exec like this:
...
$ gcc -fdebug-types-section hello.c -gdwarf-5
...
we run into:
...
$ readelf -w a.out > READELF
readelf: Warning: Unexpected form 20 encountered whilst finding \
  abbreviation for type
...

Fix this by handling DW_FORM_ref_sig8 conservatively in
get_type_abbrev_from_form.

binutils/ChangeLog:

2021-02-09  Tom de Vries  <tdevries@suse.de>

	PR binutils/27370

9b87f84a35 [binutils] Handle DW_UT_skeleton/split_compile in process_debug_info 
With this exec:
...
$ gcc -gsplit-dwarf hello.c -gdwarf-5
...
we run into:
...
$ readelf -w a.out > READELF
readelf: Warning: CU at offset c7 contains corrupt or unsupported unit type: 4.
readelf: Warning: CU at offset c7 contains corrupt or unsupported unit type: 4.
...

Fix this by handling DW_UT_skeleton and DW_UT_split_compile in
process_debug_info.

Note that this just adds the parsing of DWO_id, but not yet any printing of
it.

Tested on x86_64-linux.

f478212851 libtool.m4: update GNU/Hurd test from upstream. In upstream libtool, 47a889a4ca20 ("Improve GNU/Hurd support.") fixed detection of shlibpath_overrides_runpath, thus avoiding unnecessary relink. This backports it.

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.
