7bede82892 Don't crash if dwarf_decode_macro_bytes's 'body' is NULL
Hi,

Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1708192
      https://bugzilla.redhat.com/show_bug.cgi?id=1708786

During the Fedora RPM build process, gdb-add-index is invoked to
extract the DWARF index from the binary, and GDB will segfault because
dwarf2read.c:parse_definition_macro's 'body' variable is NULL.

The underlying problem is that Fedora's rpm-build's "debugedit"
program will silently corrupt .debug_macro strings when a binary is
compiled with -g3.  This is being taken care of by Mark Wielaard,
here:

  https://bugzilla.redhat.com/show_bug.cgi?id=1708786

However, I still feel it's important to make GDB more resilient
against invalid DWARF input, so I'm proposing this rather simple patch
to catch the situation when "body == NULL" (i.e., it's probably been
corrupted) and issue a complaint.  This is not a real fix to the
problem, of course, but at least GDB is able to finish without
segfaulting.

OK for master?

8f02ae5bac .file file number checking
This adds another test for file numbers given in .file directives,
checking that the value can be represented as an unsigned int and that
a memory allocation expression doesn't overflow.  I removed a test
added recently since an earlier test (num < 1) already covers the
(num < 0) case.

	* dwarf2dbg.c: Whitespace fixes.
	(get_filenum): Don't strdup "file".  Adjust error message.
	(dwarf2_directive_filename): Use an unsigned type for "num".

c5358db468 GDB (s12z): Improve reliability of the stack unwinder.
Previously, the stack unwinder searched through consecutive bytes for values
which it thought might be the start of a stack mutating operation.
This was error prone, because such bytes could also be the operands of other
instructions.  This change uses the opcodes api to interpret the code in each
frame.

	* s12z-tdep.c (push_pull_get_stack_adjustment): New function.
	(advance, posn, abstract_read_memory): New functions.

c408a94f81 Fix assertion failure in coerce_unspec_val_to_type
coerce_unspec_val_to_type does:

      set_value_address (result, value_address (val));

However, this is only valid for lval_memory.  This patch changes this
code to only set the address for lval_memory values.

This seems like an ordinary oversight in coerce_unspec_val_to_type,
and a test case would be difficult to write, so I'm submitting it
without a test case.

Tested on x86-64 Fedora 29; plus using an Ada program that exhibits
the bug (but which cannot be shared).
