Alan Modra 005d79fd61 PowerPC .gnu.attributes
This patch extends Tag_GNU_Power_ABI_FP to cover long double ABIs,
makes the assembler warn about undefined tag values, and removes
similar warnings from the linker.  I think it is better to not
warn in the linker about undefined tag values as future extensions to
the tags then won't result in likely bogus warnings.  This is
consistent with the fact that an older linker won't warn on an
entirely new tag.

Jose E. Marchesi b19753ce31 bfd: allow negative offsets to _GLOBAL_OFFSET_TABLE_ in elf64 SPARC
The code compiled with the -fpic model in SPARC uses 13-bit signed
immediate PC-relative loads to fetch entries from the GOT table.  In
theory this would allow using a GOT table (.got section) containing up
to 1024 entries in elf32 or 512 entries in elf64.

However, in elf64 sparc GNU targets _GLOBAL_OFFSET_TABLE_ is always
placed at the beginning of the .got section, making it impossible to use
negative offsets.  This limits the usage of -fpic to GOT tables
containing a maximum of 257 entries in elf64.

This patch activates an optimization that is already used in sparc-elf32
also in sparc-elf64, that sets _GLOBAL_OFFSET_TABLE_ to point 0x1000
into the .got section if the section size is bigger than 0x1000.

Senthil Kumar Selvaraj bf1865065f Fix PR ld/20545 - relaxation bugs in avr backend
Prior to the patch, addends for relocs were being adjusted even if
they went beyond an alignment boundary. This is wrong - to
preserve alignment constraints, the relaxation logic adds as many padding
bytes at the alignment boundary as was deleted, so addends beyond the
boundary should not be adjusted. avr-prop-7.s reproduces this
scenario.

Also, prior to this patch, the relaxation logic assumed that the addr
parameter pointed to the middle of the instruction to be deleted, and
that addr - count would therefore be the shrinked instruction's
address. This is true when actually shrinking instructions.

The alignment constraints handling logic also invokes the same logic
though, with addr as the starting offset of padding bytes and
with count as the number of bytes to be deleted. Calculating the
shrinked insn's address as addr - count is obviously wrong in this
case - that offset would point to count bytes before the last
non-padded byte. avr-prop-8.s reproduces this scenario.

To fix scenario 1, the patch adds an additional check to ensure reloc addends
aren't adjusted if they cross a shrink boundary. The shrink boundary
is either the section size or an alignment boundary. Addends pointing
at an alignment boundary don't need to be adjusted, as padding would
occur and keep the boundary the same. Addends pointing at section size
need to be adjusted though, as no padding occurs and the section size
itself would get decremented. The patch records whether padding
occured (did_pad) and uses that to detect and handle this condition.

To fix scenario 2, the patch adds an additional parameter
(delete_shrinks_insn) to elf32_avr_relax_delete_bytes to distinguish
instruction bytes deletion from padding bytes deletion. It then uses that to
correctly set shrinked_insn_address.
