Currently the EXCLUDE_FILE linker script construct can only be used
within the input section list, and applied only to the section pattern
immediately following the EXCLUDE_FILE. For example:
*.o (EXCLUDE_FILE (a.o) .text .rodata)
In this case all sections matching '.text' are included from all files
matching '*.o' but not from the file 'a.o'. All sections matching
'.rodata' are also included from all files matching '*.o' (incluing from
'a.o').
If the user wants to restrict the inclusion of section '.rodata' so that
this too is not taken from the file 'a.o' then the above example must be
extended like this:
*.o (EXCLUDE_FILE (a.o) .text EXCLUDE_FILE (a.o) .rodata)
However, due to the internal grammar of the linker script language the
snippet 'EXCLUDE_FILE (a.o) .text' is parsed by a pattern called
'wildcard_spec'. The same 'wildcard_spec' pattern is also used to parse
the input file name snippet '*.o' in the above examples. As a result of
this pattern reuse within the linker script grammar then the following
is also a valid linker script construct:
EXCLUDE_FILE (a.o) *.o (.text .rodata)
However, though the linker accepts this without complaint the
EXCLUDE_FILE part is silently ignored and has no effect.
This commit takes this last example and makes it a useful, valid,
construct. The last example now means to include sections '.text' and
'.rodata' from all files matching '*.o' except for the file 'a.o'.
If the list of input sections is long, and the user knows that the file
exclusion applies across the list then the second form might be a
clearer alternative to replicating the EXCLUDE_FILE construct.
I've added a set of tests for EXCLUDE_FILE to the linker, including
tests for the new functionality.

When creating object files during testing, base the name of the object
file on the name of the source file, rather than using dump0.o,
dump1.o, etc. There's a few places where we have multiple source
files with the same name but in different directories, in these cases,
even after this change, we still add a numerical suffix to make the
object file names unique. So if we have 'foo/src.s' and 'bar/src.s',
we will create object files 'src.o' and 'src1.o'.
Update the few tests that hard code the object file name into the
expected test results.
ld/ChangeLog:
* testsuite/lib/ld-lib.exp (run_dump_test): Use object file names
based on the original source file name.

Add the xc16x-elf target to the list of targets that do not support
the -shared option. Being missing from this list was causing the
linker to add '-z norelro' to the link line of many tests, which in
turn caused these tests to fail.

* testsuite/lib/ld-lib.exp (check_shared_lib_support): Add
xc16x-*-elf to the list of targets that don't support -shared.

Rename file_NAME_list to section_NAME_list in the linker's grammar
file. This rename reflects how the pattern is now being used, and makes
the grammar easier to understand.
There should be no functional change after this commit.

* ldgram.y: Rename file_NAME_list to section_NAME_list
throughout.

This patch stop --gc-sections elf_gc_sweep_symbol localizing symbols
that ought to remain global.
The difficulty with always descending into output section statements
is that symbols defined by the script in such statements don't have
a bfd section when lang_do_assignments runs early in the link process.
There are two approaches to curing this problem. Either we can
create the bfd section early, or we can use a special section. This
patch takes the latter approach and uses bfd_und_section. (Creating
bfd sections early results in changed output section order, and thus
lots of testsuite failures. You can't create all output sections
early to ensure proper ordering as KEEP then stops empty sections
from being stripped.)
The wrinkle with this approach is that some code that runs at
gc-sections time needs to be made aware of the odd defined symbols
using bfd_und_section.

Most BFD linker functions take a bfd_link_info param, which reinforces
the fact that they are linker functions and allow access to linker
callbacks, eg. einfo for printing errors. I was going to use einfo
for --fatal-warnings support before I decided a better way was the
patch commit 4519d071.

Commit b751e639 regressed arm linux kernel builds, that have an
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
& ~ (((0x1 << 0xc) - 0x1))))
<= (0x1 << 0xc)), HYP init code too big or misaligned)
Due to some insanity in ld expression evaluation, the integer values
0x1 and 0xc above are treated as absolute addresses (ie. they have an
associated section, *ABS*, see exp_fold_tree_1 case etree_value) while
the expression (0x1 << 0xc) has a plain number result. The left hand
side of the inequality happens to evaluate to a "negative" .text
section relative value. Comparing a section relative value against an
absolute value works since the section relative value is first
converted to absolute. Comparing a section relative value against a
number just compares the offsets, which fails since the "negative"
offset is really a very large positive number.
This patch works around the problem by folding integer expressions, so
the assert again becomes
ASSERT (((__hyp_idmap_text_end - (__hyp_idmap_text_start
& 0xfffffffffffff000))
<= 0x1000), HYP init code too big or misaligned)

This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs,
makes the assembler warn about undefined tag values, and removes
similar warnings from the linker. I think it is better to not
warn in the linker about undefined tag values as future extensions to
the tags then won't result in likely bogus warnings. This is
consistent with the fact that an older linker won't warn on an
entirely new tag.

SVE defines new names for existing NZCV conditions, to reflect the
result of instructions like PTEST. This patch adds support for these
names.
The patch also adds comments to the disassembly output to show the
alternative names of a condition code. For example:
cinv x0, x1, cc
becomes:
cinv x0, x1, cc // cc = lo, ul, last
and:
b.cc f0 <...>
becomes:
b.cc f0 <...> // b.lo, b.ul, b.last
Doing this for the SVE names follows the practice recommended by the
SVE specification and is definitely useful when reading SVE code.
If the feeling is that it's too distracting elsewhere, we could add
an option to turn it off.

There was a gap in the documentation of EXCLUDE_FILE that could cause
confusion to a user. When writing an input section specifier like this:
*(EXCLUDE_FILE (somefile.o) .text .text.*)
this could mean one of the following:
1. All '.text' and '.text.*' from all files except for 'somefile.o',
or
2. All '.text' from all files except 'somefile.o', and all '.text.*'
sections from all files.
It turns out that the second interpretation is correct, but the manual
does not make this clear (to me at least). Hopefully this patch makes
things clearer.

Prior to the patch, addends for relocs were being adjusted even if
they went beyond an alignment boundary. This is wrong - to
preserve alignment constraints, the relaxation logic adds as many padding
bytes at the alignment boundary as was deleted, so addends beyond the
boundary should not be adjusted. avr-prop-7.s reproduces this
scenario.
Also, prior to this patch, the relaxation logic assumed that the addr
parameter pointed to the middle of the instruction to be deleted, and
that addr - count would therefore be the shrinked instruction's
address. This is true when actually shrinking instructions.
The alignment constraints handling logic also invokes the same logic
though, with addr as the starting offset of padding bytes and
with count as the number of bytes to be deleted. Calculating the
shrinked insn's address as addr - count is obviously wrong in this
case - that offset would point to count bytes before the last
non-padded byte. avr-prop-8.s reproduces this scenario.
To fix scenario 1, the patch adds an additional check to ensure reloc addends
aren't adjusted if they cross a shrink boundary. The shrink boundary
is either the section size or an alignment boundary. Addends pointing
at an alignment boundary don't need to be adjusted, as padding would
occur and keep the boundary the same. Addends pointing at section size
need to be adjusted though, as no padding occurs and the section size
itself would get decremented. The patch records whether padding
occured (did_pad) and uses that to detect and handle this condition.
To fix scenario 2, the patch adds an additional parameter
(delete_shrinks_insn) to elf32_avr_relax_delete_bytes to distinguish
instruction bytes deletion from padding bytes deletion. It then uses that to
correctly set shrinked_insn_address.
