It seems like this macro is not needed at all anymore, it just wraps the
function of the same name with the same arguments.

Add a getter and a setter for a symtab's compunit_symtab.  Remove the
corresponding macro and adjust all callers.

For brevity, I chose the name "compunit" instead of "compunit_symtab"
the the field, getter and setter names.  Since we are already in symtab
context, the _symtab suffix seems redundant.

510860f278 gdb: remove COMPUNIT_FILETABS macro 
I think that most remaining uses of COMPUNIT_FILETABS intend to get the
primary filetab of the compunit_symtab specifically (and not to iterate
over all filetabs, for example, those cases would use compunit_filetabs,
which has been converted to compunit_symtab::filetabs), so replace mosts
uses with compunit_symtab::primary_filetab.

In jit.c, function finalize_symtab, we can save the symtab object
returned by allocate_symtab and use it, it makes things simpler.

102cc23543 gdb: move compunit_filetabs to compunit_symtab::filetabs 
Make compunit_filetabs, used to iterate a compunit_symtab's filetabs, a
method of compunit_symtab.  The name filetabs conflicts with the current
name of the field.  Rename the field to m_filetabs, since at this point
nothing outside of compunit_symtab uses it, so we should treat it as
private (even though it's not actually private).  Rename the
last_filetab field to m_last_filetab as well (it's only used on
compunit_symtab::add_filetab).

Adjust the COMPUNIT_FILETABS macro to keep its current behavior of
returning the first filetab.

a723766c0e Allow non-ASCII characters in Rust identifiers 
Rust 1.53 (quite a while ago now) ungated the support for non-ASCII
identifiers.  This didn't work in gdb.  This is PR rust/20166.

This patch fixes the problem by allowing non-ASCII characters to be
considered as identifier components.  It seemed simplest to just pass
them through -- doing any extra checking didn't seem worthwhile.

The new test also verifies that such characters are allowed in strings
and character literals as well.  The latter also required a bit of
work in the lexer.

c1f5e54825 Fix Rust parser bug with function fields 
In Rust, 'obj.f()' is a method call -- but '(obj.f)()' is a call of a
function-valued field 'f' in 'obj'.  The Rust parser in gdb currently
gets this wrong.  This is PR rust/24082.

The expression and Rust parser rewrites made this simple to fix --
simply wrapping a parenthesized expression in a new operation handles
it.  This patch has a slight hack because I didn't want to introduce a
new exp_opcode enumeration constant just for this.  IMO this doesn't
matter, since we should work toward removing dependencies on these
opcodes anyway; but let me know what you think of this.

026fbfa60e gdb/doc: update docs for 'info win' and 'winheight' commands 
This started by noticing that the docs for 'winheight' are out of
date, the docs currently give a specific list of possible window
names.  However, now that windows can be implemented in Python, it is
not possible to list all possible names.

I now link the user to a mechanism by which they can discover the
valid names for themselves at run time (by using 'info win').  That,
and the fact that gdb provides tab-completion of the name at the
command line, feels good enough.

Finally, I noticed that the docs for 'win info' don't explicitly say
that the name of the window is given in the output.  This could
probably have been inferred, but given I'm now linking to this as a
mechanism to find the window name, I'd prefer to mention that the name
can be found in the output.

f62843d751 gdb/tui: add window width information to 'info win' output 
Now that we support horizontal window placement in the tui, it makes
sense to have 'info win' include the width, as well as the height, of
the currently visible windows.

That's what this commit does.  Example output is now:

  (gdb) info win
  Name       Lines Columns Focus
  src           12      40 (has focus)
  asm           12      41
  status         1      80
  cmd           11      80

I've added a NEWS entry, but the documentation was already suitably
vague, it just says that 'info win' displays the size of the visible
windows, so I don't think anything needs to be added there.

I've also added some tests, as far as I could find, the 'info win'
command was previously untested.

8df52eeeb0 Detect .eh_frame_hdr earlier for SIZEOF_HEADERS 
Current code detects the need for PT_GNU_EH_FRAME using a field set by
_bfd_elf_discard_section_eh_frame_hdr, which is called fairly late in
the linking process.  Use the elf hash table eh_info instead, which is
set up earlier by size_dynamic_sections.

bf484e9348 sim: Allow toggling of quiet NaN-bit semantics 
IEEE754-1985 specifies the top bit of the mantissa as an indicator
of signalling vs. quiet NaN, but does not define the precise semantics.
Most architectures treat this bit as indicating quiet NaN, but legacy
(pre-R6) MIPS goes the other way and treats it as signalling NaN.

This used to be controlled by a macro that was only defined for MIPS.
This patch replaces the macro with a variable to track the current
semantics of the NaN bit and allows differentiation between older
(pre-R6) and and newer MIPS cores.

565c20212a ld: Remove emultempl/armcoff.em 
Remove emultempl/armcoff.em which has been unused after

commit 2ac93be706
Author: Alan Modra <amodra@gmail.com>
Date:   Mon Apr 16 20:33:36 2018 +0930

    Remove arm-aout and arm-coff support

    This also removes arm-netbsd (not arm-netbsdelf!), arm-openbsd, and
    arm-riscix.  Those targets weren't on the obsolete list but they are
    all aout, and it doesn't make all that much sense to remove arm-aout
    without removing them too.

	* emultempl/armcoff.em: Removed.

4a620b7e30 gdb: include jit_code_entry::symfile_addr value in names of objfiles created by jit reader API 
This commit includes the JIT object's symfile address in the names of
objfiles created by JIT reader API (e.g., << JIT compiled code at
0x7ffd8a0c77a0 >>).  This allows one to at least differentiate one from
another.

The address is the one that the debugged program has put in
jit_code_entry::symfile_addr, and that the JIT reader's read function
receives.  As we can see in gdb.base/jit-reader-host.c and
gdb.base/jit-reader.c, that may not be the actual value of where the
JIT-ed code is.  But it is a value chosen by the author of the JIT
engine and the JIT reader, so including this value in the objfile name
may help them correlate the JIT objfiles created by with their logs /
data structures.

To access this field, we need to pass down a reference to the
jit_code_entry.  So make jit_dbg_reader_data a structure (instead of an
alias for a CORE_ADDR) that includes the address of the code entry in
the inferior's address space (the previous meaning of
jit_dbg_reader_data) plus a reference to the jit_code_entry as read into
GDB's address space.  And while at it, pass down the gdbarch, so that we
don't have to call target_gdbarch.

480157863b Improve Ada unchecked union type printing 
Currently, "ptype" of an Ada unchecked union may show a
compiler-generated wrapper structure in its output.  It's more
Ada-like to elide this structure, which is what this patch implements.
It turned out to be simplest to reuse a part of print_variant_clauses
for this.

As this is Ada-specific, and Joel already reviewed it internally, I am
going to check it in.

I noticed that host_hex_value is redundant, because gdbsupport already
has fromhex.  This patch removes the former in favor of the latter.

fd3c53675c Support symbol+offset lookup in addr2line 
The Linux kernel usually ouputs symbol+offset instead of plain code
addresses these days, to avoid leaking ASLR secrets and to handle
dynamically loaded modules.

Converting those with addr2line is somewhat involved: it requires
looking up the symbol first using nm and then manually compute the
offset, and then pass it to addr2line.

This patch implements the necessary steps directly in addr2line,
by looking up the symbol (with demangling if needed) and computing
the offset.

It's possible that a symbol is ambigious with a hex number. In this
case it uses the symbol lookup if the string contains a +. When it isn't
ambigious the + is optional.
