* NEWS: Mention change in linker script expression evaluation.
2010-08-19 Alan Modra <amodra@gmail.com>
* ld.texinfo (Expression Section): Detail expression evaluation.
(Builtin Functions <ADDR>): Correct.
(Builtin Functions <LOADADDR>): Don't mention LOADADDR normally
the same as ADDR.
(Builtin Functions <SEGMENT_START>): Typo fix.
* ldexp.c (new_number): New function.
(make_abs, exp_get_abs_int): Cope with NULL expld.result.section.
(fold_unary <'~', '!', '-'>): Don't make_abs.
(fold_binary): Simplify result section logic. Return NULL section
for logical ops.
(fold_binary <SEGMENT_START>): Use new_rel_from_abs to set value to
a consistent result.
(fold_name <SIZEOF_HEADERS>): Return new_number, not new_abs.
(fold_name <DEFINED, SIZEOF, ALIGNOF, LENGTH, CONSTANT>): Likewise.
(fold_name <NAME>): No need to handle absolute symbols differently
from relative ones.
(fold_name <ORIGIN>): Don't return valid result when
lang_first_phase_enum. Return new_rel_from_abs, not new_abs.
(exp_fold_tree_1 <etree_value>): Return new_number, not new_rel.
(exp_fold_tree_1): Ajust for NULL expld.result.section. When assigning
a plain number to dot, assume the value is relative to expld.section.
Make terms not in an output section, absolute.
* ldlang.c (print_assignment): Fix style nit.

using expld.result.section rather than expld.section.
