This patch updates add-symbol-file help and error text.
It changes add-symbol-file to throw an exception if "-s" is seen but
not all of the arguments are given. Previously this was silently
ignored.
It changes the unrecognized argument message to more clearly state
what went wrong.
Finally, it updates the usage line in the help text to follow GNU
style regarding "metasyntactic variables"; a change I believe should
be made to all gdb help messages.

LLVM is experimenting with placing .eh_frame sections in the COMDAT group
with the function's text. This triggers an internal error in gold because
we don't expect to see but one .eh_frame section in an object, and we use
a single data member in class Sized_relobj_file to keep track of that section.
This patch removes that data member, and instead checks the output section
and the input section offset to identify an optimized .eh_frame section.

This patch processes linker script assignment statements before ld
opens DT_NEEDED libraries, in order to define symbols like __bss_start
that might also be defined by a library, falsely triggering an error
about "DSO missing from command line".
The initial value won't be correct when assigning a symbol from dot,
and I make no attempt to handle all expressions. For example, an
assignment like "_start_foo = ADDR (.foo)" isn't valid until sections
are laid out, so won't define _start_foo early. What's here should be
enough for most common scripts, and hopefully won't perturb fragile
scripts.

There is a call to update_definedness between code that evaluates an
assignment expression value and code that transfers symbol
attributes. When script assignment expressions contain DEFINED, that
can mean the wrong symbol type is copied. This patch tracks symbols
read during expression evaluation, rather than examining the
expression and re-evaluating conditionals. Not only does this
simplify the code, it also means ld can now copy symbol types in more
complex expressions.
An unfortunate side effect of copying symbol type for more complex
expressions affects mmix, which uses
PROVIDE (Main = DEFINED (Main) ? Main : (DEFINED (_start) ? _start : _start.));
in a default script. So now _start or _start. symbol type may be
copied, losing the function type specially set up for Main. This can
be avoided by making bfd_copy_link_hash_symbol_type do nothing for
mmix.

The fix for PR 19291 broke some other cases where -r is used with scripts,
as reported in PR 22266. The original fix for PR 22266 ended up breaking
many cases for REL targets, where the addends are stored in the section data,
and are not being adjusted properly.
The problem was basically that in a relocatable output file (ET_REL),
symbol values are supposed to be relative to the start address of their
section. Usually in a relocatable file, all sections start at 0, so the
failure to get this right is often irrelevant, but with a linker script,
we occasionally see an output section whose starting address is not 0,
and gold would occasionally write a symbol with its relocated value instead
of its section-relative value.
This patch reverts the recent fix for PR 22266 as well as my original fix
for PR 19291. The original fix moved the symbol value adjustment to
write_local_symbols, but neglected to undo a few places where the adjustment
was also being applied, resulting in an occasional double adjustment. The
more recent fix removed those other adjustments, but then failed to
re-account for the adjustment when rewriting the relocations on REL targets.
With the old attempts reverted, we now apply the symbol value adjustment to
the one case that had been missed (non-section symbols in merge sections).
But now we also need to account for the adjustment when rewriting the addends
for RELA relocations.

Replace linked list of trampoline frags with an ordered array, so that
instead of indexing fixups trampolines could be indexed. Keep each array
in the trampoline_seg structure, so there's no need to rebuild it for
every new processed segment. Don't run relaxation for each trampoline
frag, instead run it for each fixup in the current segment that needs
relaxation at the beginning of each relaxation pass. This way the
complexity of this process drops from about O(n^2 * m) to about
O(log n * m), where n is the number of trampoline frags and m is the
number of fixups that need relaxation in the segment.

The following patch introduced a new feature related to Ada exception
catchpoints:
commit e547c119d0
Author: Joel Brobecker <brobecker@adacore.com>
Date: Fri Nov 24 17:09:42 2017 -0500
Subject: (Ada) provide the exception message when hitting an exception catchpoint
Unfortunately, the patch left 2 errors in gdb.ada/mi_catch_ex.exp,
both inside the "continue_to_exception" function:
1. The exception message on the console can include the exception
message, and thus this patch adjust the expected output in
the corresponding gdb_expect call to allow it;
to allow it.
2. There was a TCL syntax confusion in "$exception_name(..."
that caused TCL to evaluate "exception_name as an array,
rather than as a variable. This patch fixes this by escaping
the '(' (and the corresponding closing parenthesis, for
consistency).
gdb/testsuite/ChangeLog:
* gdb.ada/mi_catch_ex.exp (continue_to_exception): Adjust
expected output in gdb_expect call to allow the exception
message to be present as well. Fix syntax confusion to avoid
TCL thinking that exception_name is an array.
