* NEWS: Mention change in linker script expression evaluation.
ld/
* 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.

(lang_do_assignments_1): Likewise.
ld/testsuite/
* ld-scripts/memory.t: Remove ORIGIN fudge.
The example version script in the manual currently suggests:
extern "C++" { "int f(int, double)"; }
But a C++ function like that doesn't encode the return type into the
mangled name, so when the linker demangles things, it ends up with
"f(int, double)" and so it never matches.
The example also lacks a trailing semicolon after the brace, so the
linker always complains about a syntax error in the file.
While the language section documents the possibilities, it isn't clear
as to which is the default language. So explicitly state that the C
language is the default.
