Alan Modra e0a3af227e Revert ALIGN changes 
Reverts a2c59f28 and e474ab13.  Since the unary form of ALIGN only
references "dot" implicitly, there isn't really a strong argument for
making ALIGN use a relative value when inside an output section.

	* ldexp.c (align_dot_val): Delete.
	(fold_unary <ALIGN_K, NEXT>): Revert 2015-07-10 change.
	(is_align_conditional): Revert 2015-07-20 change.
	(exp_fold_tree_1): Likewise, but keep expanded comment.
	* scripttempl/elf.sc (.ldata, .bss): Revert 2015-07-20 change.
	* ld.texinfo (<ALIGN>): Correct description.

Alan Modra d9d11c361c ALIGN change affects cris scripts 
More fallout from a2c59f28.  This one could have been fixed by simply
using ". = ALIGN (ABSOLUTE (.), 2);" but it's nicer to align the
section.

	* emulparams/criself.sh (INIT_ADDR, FINI_ADDR): Define.
	(INIT_START, FINI_START): Don't ALIGN.
	* scriptempl/elf.sc (.init, .fini): Apply INIT_ADDR/FINI_ADDR.

Alan Modra e474ab13ec ALIGN change affects standard scripts 
a2c59f28 changed the way the unary ALIGN behaved inside output sections,
resulting in cris-elf testsuite regressions.  This patch pads out .bss
in the same manner as it was prior to the ALIGN change.

	* scripttempl/elf.sc (.ldata, .bss): Align absolute value of dot.
	* ldexp.c (is_align_conditional): Handle binary ALIGN.
	(exp_fold_tree_1): Move code setting SEC_KEEP for assignments to
	dot inside output sections.  Handle absolute expressions.

Alan Modra 6c1aca3e2d Start of relro segment adjustment 
Adjusting the start of the relro segment in order to make it end
exactly on a page boundary runs into difficulties when sections in the
relro segment are aligned;  Adjusting the start by (next_page - end)
sometimes results in more than that adjustment occurring at the end,
overrunning the page boundary.  So when that occurs we try a new lower
start position by masking the adjusted start with the maximum section
alignment.  However, we didn't consider that this masked start address
may in fact be before the initial relro base, which is silly since
that can only increase padding at the relro end.

I've also moved some calculations closer to where they are used, and
comments closer to the relevant statements.

	* ldlang.c (lang_size_sections): When alignment of sections
	results in relro base adjustment being too large, don't go lower
	than the initial value.
	* ldexp.c (fold_binary <DATA_SEGMENT_RELRO_END>): Comment.
	* scripttempl/elf.sc (DATA_SEGMENT_ALIGN): Omit SEGMENT_SIZE
	alignment when SEGMENT_SIZE is the same as MAXPAGESIZE.

Alan Modra 5ad18f16ab Reorder more powerpc64 sections again for -z relro 
.toc1 is the second level TOC section used by gcc's -mminimal-toc.  It
too should be read-only after relocation.  Also, the last patch
description mentioned .sbss moving but didn't actually do that, so fix
that problem.  .tocbss (whatever that is) was before .sbss previously,
so move that one too.

	* emulparams/elf64ppc.sh (OTHER_SDATA_SECTIONS): Use in place of..
	(OTHER_BSS_SYMBOLS): ..this.
	(OTHER_PLT_RELOC_SECTIONS): Don't define.
	(OTHER_GOT_RELOC_SECTIONS): Add rela.toc1 and rela.tocbss.

	(OTHER_RELRO_SECTIONS_2): ..here.
	* scripttempl/elf.sc: Move SBSS too when DATA_SDATA.
 2015-01-20 21:46:07 +10:30
Alan Modra 23283c1be0 Reorder more powerpc64 sections for -z relro 
This moves .got too, which requires .sdata and .sbss to move with it,
because these sections share addressing via the toc pointer and with
small-model code must be within a 16-bit signed offset.  .plt, .iplt
and .branch_lt must also be moved since they are addressed via a
32-bit offset from the toc pointer, and we might have a very large
.data section.

This change means we may have some bss style sections before the data
segment, necessitating another PT_LOAD header.  Also, since _edata is
defined at the end of the data segment it's possible with an empty
.data to have _edata at the end of .plt which looks a little unusual
since .plt is a bss style section.  That should only happen rarely in
real world binaries, but does occur in the ld testsuite.
