62e6b7b3b3 [LVu] base subseg head view on prev subseg's tail
Location views at borders between subsegments/subsections in the same
segment/section are computed as if each new subsegment/subsection
started with a forced view reset to zero, but the line number program
does not introduce resets that are not explicitly requested, so if a
subsegment ends at the same address another starts, the line number
program will have a continuity of views at the border address, whereas
the initial view number label in the latter subsegment will be
miscomputed as zero.

This patch delays the assignment of view expressions at subsegment
heads to the time of chaining the frags of subsegments into a single
segment, so that they are set based on the view at the end of the
previous subsegment in the same segment.

The line number program created for the test program had an
unnecessary DW_LNS_advance_pc at the end.  This patch also arranges
for us not to emit it.

204f543cae dwarf2: Align relocation within .debug_line section
All relocations specify a byte address.  As dwarf debug information is
organized in octets, some relocations may not be aligned.  While it
might be possible to define special relocations that operate at an
octet offset from their address, it's easier to ensure the relocations
are aligned by padding with "nop" statements.

In most dwarf sections this requirement is already fulfilled, only
relocations for symbol address within the .debug_line section can be
misaligned.

145c4477d2 dwarf2: Pad size of .debug_line section.
As all dwarf debug information is organized in octets, the size of all
dwarf sections must be aligned to OCTETS_PER_BYTE.  Most DWARF sections
meet this requirement, only the .debug_line section can reach an
arbitrary octet size.

In order to align the size to a multiple of OCTETS_PER_BYTE, the section
is padded with "nop" statements at the end.

38cf168be5 PR23040, .uleb128 directive doesn't accept some valid expressions
What a trip down a rabbit hole this bug has been.

First observation: You can't use deferred_expression in s_leb128.
deferred_expression implements the semantics of .eqv or '==', saving
an expression with minimal simplification for assignment to a symbol
so that the expression is evaluated at uses of the symbol.  In
particular, the value of "dot" is not evaluated at the .eqv symbol
assignment, but later.  When s_leb128 uses deferred_expression,
"later" is at the end of assembly, giving entirely the wrong value of
"dot".  There is no way to fix this for the s_leb128 use without
breaking .equ (which incidentally was already somewhat broken, see
commit e4c2619ad1).  So, don't use deferred_expression in s_leb128.

But that leads to the gas test elf/dwarf2-17 failing, because view
symbols are calculated with a chain of expression symbols.  In the
dwarf2-17 .L1 case there is a "temp_sym_1 > temp_sym_2" expression,
with temp_sym_1 and temp_sym_2 on either side of a ".balign".  Since
".balign" and many other directives moving "dot" are not calculated on
the first (and only) pass over source, .L1 cannot be calculated until
final addresses are assigned to frags.  However, ".uleb128 .L1" *is*
calculated immediately, resulting in the wrong value.

The reason why .L1 is calculated immediately is that code in
expr.c:operand after the comment
	  /* If we have an absolute symbol or a reg, then we know its
	     value now.  */
does as it says and fixes the value of .L1, because .L1 is assigned
to absolute_section in dwarf2dbg.c:set_or_check_view.  So, correct
that to expr_section.

Unfortunately that fix leads to failure of the elf/dwarf2-5 test with
../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L5'
../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L11'
../gas/elf/dwarf2-5.s: Error: attempt to get value of unresolved symbol `.L12'
So why is that?  Well, it turns out that .L5 is defined in terms of
.L4, and apparently .L4 is undefined.  But .L4 clearly is defined,
otherwise we would hit an error when trying to use .L4 a little
earlier.  There are two copies of .L4!  So, symbols are cloned when
that should not happen.

Symbol cloning is a technique used by gas to support saving the value
of symbols that change between uses, but that isn't the case with
.L4.  Only one value is set and used for .L4, but indeed .L4 was being
cloned by symbol_clone_if_forward_ref.  This despite no forward refs
being present.  Also, .L4 is a local symbol and a cursory glance at
symbol_clone_if_forward_ref "if (symbolP && !LOCAL_SYMBOL_CHECK (symbolP))"
would seem to prevent cloning of local symbols.  All is not as it
seems though, a curse of using macros.  LOCAL_SYMBOL_CHECK modifies
its argument if a "struct local_symbol" is converted to the larger
"struct symbol", as happens when assigning a view symbol value.
That fact results in the recursive call to symbol_clone_if_forward_ref
returning a different address for "add_symbol".  This problem could
have been fixed by using symbol_same_p rather than comparing symbol
pointers, but I thought it better to use the real symbol throughout.
Note that symbol_find_exact also returns the real symbol for a
converted local symbol.

Finally, this patch does expose lack of support for forward symbol
definitions in various targets.  For example:
alpha-linux  +ERROR: ../ld/testsuite/ld-elf/pr11138-2.c: compilation failed
This is caused by view symbol uses.  On alpha-linux-gcc (GCC) 8.1.1
20180502 they happen to occur in .byte directives so were silently
broken in cases like elf/dwarf2-17 anyway.

md_apply_fix on those targets needs to handle fixups that resolve down
to a constant.

49fced1206 gas: Emit name, comp_dir and producer strings in .debug_str.
Putting the name, comp_dir and producer strings in the .debug_str section
makes it possible to share them across CUs. This saves a small amount of
space (about ~20K on a glibc libc.so.6 build with debuginfo). And makes
it easier for tools like rpm debugedit to adjust the source paths when
generating separate debuginfo files.

gas/
       * dwarf2dbg.c (out_debug_abbrev): Use DW_FORM_strp instead of
       DW_FORM_string for DW_AT_name, DW_AT_comp_dir and DW_AT_producer.
       (out_debug_info): Accept symbols to name, comp_dir and producer
       in the .debug_str section and emit those offsets not full strings.
       (out_debug_str): New function that outputs the strings for name,
       comp_dir and producer in .debug_str and generates symbols to
       those strings.
       (out_debug_line): Create a .debug_str section if necessary and
       call out_debug_str before calling out_debug_info.
       * testsuite/gas/aarch64/dwarf.d: Add extra section symbol to
       expected output.

d025d5e5b5 gas: Don't use frag_align but use plain padding to align .debug_aranges.
out_debug_aranges uses frag_align to make sure the addresses start
out aligned. Using frag_align will call frag_var[_init], which will
end up calling TC_FRAG_INIT. On arm and aarch64 TC_FRAG_INIT will
generate a $d mapping symbol for the .debug_aranges to show that at
that point a sequence of data items starts.

Such a symbol pointing into a non-allocated debug section will confuse
eu-strip -g. And it seems inefficient and wrong in general to have
additional mapping symbols for debug sections, which won't contain
actual code in the first place.

Just keep track of the aranges header size and use plain padding to
align the addresses which avoids generating any mapping symbols on
aarch64 and arm.

Includes a testcase for aarch64 that PASS with this patch and shows
the extra $d mapping symbol in .debug_aranges before.

62ebcb5cbe gas TC_PARSE_CONS_EXPRESSION communication with TC_CONS_FIX_NEW
A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION
to TC_CONS_FIX_NEW via static variables.  That's OK, but not best
practice.  tc-ppc.c goes further in implementing its own replacement
for cons(), because the generic one doesn't allow relocation modifiers
on constants.  This patch fixes both of these warts.
