    • DWARF: Add .debug_addr table header for dwarf_version >= 5. · 171b0a01 
      GNU DebugFission didn't add table headers for the .debug_addr
tables, but DWARF5 does. The table header makes it possible
for a DWARF consumer to parse the address tables without having
to index all .debug_info CUs first.

We can keep using the .debug_addr section label as is, because the
DW_AT_[GNU_]addr_base attribute points at the actual address index,
which starts right after the table header. So the label is generated
at the correct location whether the header is added first or not.

Add DW_AT_addr_base instead of DW_AT_GNU_addr_base to the skeleton
CU DIE for DWARF5.

	* dwarf2out.c (dwarf2out_finish): Add .debug_addr table header for
	dwarf_version >= 5.
	(dwarf_AT): Handle DW_AT_addr_base.
	(add_top_level_skeleton_die_attrs): Use dwarf_AT for DW_AT_addr_base.

(we have no support for hard-float n64 MIPS16 code generation), which 
means that the test case will fail, as the regular expression pattern 
expects `lw' and `.word' rather than `ld' and `.dword' respectively to 
appear in assembly code generation.  Correct the pattern in an obvious 
way then making it accept both intructions and pseudo-ops.

	gcc/testsuite/
	* gcc.target/mips/data-sym-pool.c (dg-options): Match `ld' and
	`.dword' in addition to `lw' and `.word'.

    • MIPS/GCC/testsuite: Fix data-sym-pool.c for SVR4 model at -O0 · 7dc5410a 
      With GCC configurations using the SVR4 rather than the PLT dynamic 
executable model and the o32 ABI with the data-sym-pool.c test case code

	.insn
	.end	frob
	.size	frob, .-frob
	.ident	"GCC: (GNU) 8.0.1 20180410 (experimental)"

causing a failure due to the unexpected `__gnu_local_gp' entry in the 
constant pool, even though there is nothing wrong with it as far as the 
annotation being examined is concerned.

Given that the SVR4 vs PLT code model consideration is irrelevant for 
this test case rather than rewriting the regular expression to match 
this variant of code just enforce the PLT model by using the `-mplt' 
option.  It is safe to use this option unconditionally as it is silently 
ignored with configurations that do not support this model, e.g. bare 
metal ELF.

	gcc/testsuite/
	* gcc.target/mips/data-sym-pool.c (dg-options): Add `-mplt'.
