Alan Modra e00e81980c Don't return DW_AT_name for function name in C++
DW_AT_name for functions typically just contains the base function
name, so lacks namespace, class and parameter information.  It would
be possible to extract all these from the DWARF, but at a considerable
complication of the parser in dwarf2.c, and then you'd need to mangle
it all together.  Much simpler is to look up the actual symbol.  This
patch does that, avoiding the extra symbol lookup when the language
doesn't do name mangling.

Alan Modra 601a03ba3d _bfd_elf_slurp_version_tables tidy
The internal verref buffer is allocated with bfd_zalloc, based on a
count given in headers.  If the headers are broken/fuzzed and contain
an enormous count the alloc can result in OOM.  If we first read the
external verrefs (into a buffer that isn't zeroed on allocation) then
the read provides a sanity check on the headers.

Also prints an error for version info that fails other sanity checks.

	* elf.c (_bfd_elf_slurp_version_tables): Delay allocation of
	internal verref buffer.  Error for zero sh_info.  Print errors.
	Check for zero vd_ndx.  Use bfd_zalloc for vd_auxptr buffer.

Alan Modra a485e98ea0 Move ELF section headers to end of object file
Currently, section ordering differs a little for non-loaded reloc
sections output by ld -emit-relocs or ld -r and that after passing
such objects through objcopy.  Not that it really matters, but it
would be better for a simple objcopy to produce an unchanged output
object file.  Also, section headers are put somewhere in the middle of
the non-loaded sections, again slightly differently for ld and
objcopy.  This patch fixes these discrepancies and puts section
headers last, which is where gold puts them, and is where
bfd_from_remote_memory wrongly assumed they will be found.

Alan Modra 5979d6b69b Handle VDSO section headers past end of page
When a VDSO gets large enough that it doesn't entirely fit in one page,
but not so large that the part described by the program header exceeds
one page, then gdb/BFD doesn't read the section headers and symbol
table information.  This patch cures that by passing the size of the
vdso to BFD, and fixes a number of other issues in the BFD code.

H.J. Lu 43a8475ca0 Adjust LOAD segment to generate GNU_RELRO segment
This patch fixes 2 GNU_RELRO segment bugs:

1. lang_size_sections didn't properly align base to the maximum
alignment power of sections between DATA_SEGMENT_ALIGN and
DATA_SEGMENT_RELRO_END.
2. ld failed to adjust LOAD segment to generate GNU_RELRO segment
when LOAD segment doesn't fit GNU_RELRO segment.  This is

https://sourceware.org/bugzilla/show_bug.cgi?id=14207

We "fixed" ld by not generating GNU_RELRO segment.  This patch
adjusts LOAD segment to generate GNU_RELRO segment.  It fixes
PR ld/16322 and at the same time it also fixes PR binutils/16323
since now we can adjust LOAD segment if it is too small.
