A long time ago ld made use of userdata to tie an output section to
its lang_input_statement_struct object file. Some time later Joern
made map file printing of symbols at lot faster, using userdata on
input sections. That complicated allocation of userdata, and when the
output section use disappeared a year later, the code wasn't properly
cleaned up. This patch does that cleanup, and also tidies the symbol
printing code to not allocate userdata where it won't be needed. We
don't print symbols defined in the absolute section or in output
sections.
* ld.h (fat_section_userdata_type, get_userdata): Move to..
* ldlang.h (input_section_userdata_type, get_userdata): ..here.
* ldlang.c (init_map_userdata): Delete. Fold into..
(sort_def_symbol): ..here. Don't attach input section userdata
to output sections or global bfd sections.
(lang_map): Don't pre-allocate input section userdata.
(init_os): Don't allocate userdata for output sections.
(print_all_symbols): Update.
Older GCC, like 4.1/4.2, will issue an uninitialized warning on
ehdr_start_save. This patch silences by using
struct bfd_link_hash_entry ehdr_start_save = ehdr_start_save;
* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
Silence uninitialized warning on ehdr_start_save with older
GCC.
Rather than hacking every backend to not discard dynamic relocations
against an undefined hidden __ehdr_start, make it appear to be defined
early. We want __ehdr_start hidden before size_dynamic_sections so
that it isn't put in .dynsym, but we do need the dynamic relocations
for a PIE or shared library with a non-PIC reference. Defining it
early is wrong if we don't actually define the symbol later to its
proper value. (In some cases we want to leave the symbol undefined,
for example, when the ELF header isn't loaded, and we don't have this
infomation available in before_allocation.)

__ehdr_start before size_dynamic_sections and restore afterwards.

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.
