The 64-bit version of binutils got support for the PE COFF BIG OBJ format a
couple of years ago. The BIG OBJ format is a slightly different COFF format
which extends the size of the number of section field in the header from a
uint16_t to a uint32_t and so greatly increases the number of sections allowed.
However the 32-bit version of bfd never got support for this. The GHC Haskell
compiler generates a great deal of symbols due to it's use of
-ffunction-sections and -fdata-sections.
This meant that we could not build the 32-bit version of the GHC Compiler for
many releases now as binutils didn't have this support.
This patch adds the support to the 32-bit port of binutils as well and also does
come cleanup in the code.

This is quite complicated because the CTF section's contents depend on
the final contents of the symtab and strtab, because it has two sections
whose contents are shuffled to be in 1:1 correspondence with the symtab,
and an internal strtab that gets deduplicated against the ELF strtab
(with offsets adjusted to point into the ELF strtab instead). It is
also compressed if large enough, so its size depends on its contents!
So we cannot construct it as early as most sections: we cannot even
*begin* construction until after the symtab and strtab are finalized.
Thankfully there is already one section treated similarly: compressed
debugging sections: the only differences are that compressed debugging
sections have extra handling to deal with their changing name if
compressed (CTF sections are always called ".ctf" for now, though we
have reserved ".ctf.*" against future use), and that compressed
debugging sections have previously-uncompressed content which has to be
stashed away for later compression, while CTF sections have no content
at all until we generate it (very late).
BFD also cannot do the link itself: libctf knows how to do it, and BFD
cannot call libctf directly because libctf already depends on bfd for
file I/O. So we have to use a pair of callbacks, one, examine_strtab,
which allows a caller to examine the symtab and strtab after
finalization (called from elf_link_swap_symbols_out(), right before the
symtabs are written, and after the strtab has been finalized), and one
which actually does the emission (called emit_ctf simply because it is
grouped with a bunch of section-specific late-emission function calls at
the bottom of bfd_elf_final_link, and a section-specific name seems best
for that). emit_ctf is actually called *twice*: once from lang_process
if the emulation suggests that this bfd target does not examine the
symtab or strtab, and once via a bfd callback if it does. (This means
that non-ELF targets still get CTF emitted, even though the late CTF
emission stage is never called for them).
v2: merged with non-ELF support patch: slight commit message
adjustments.
v3: do not spend time merging CTF, or crash, if the CTF section is
explicitly discarded. Do not try to merge or compress CTF unless
linking.
v4: add CTF_COMPRESSION_THRESHOLD. Annul the freed input ctf_file_t's
after writeout: set SEC_IN_MEMORY on the output contents so a future
bfd enhancement knows it could free it. Add SEC_LINKER_CREATED |
SEC_KEEP to avoid having to add .ctf to the linker script. Drop
now-unnecessary ldlang.h-level elf-bfd.h include and hackery around
it. Adapt to elf32.em->elf.em and elf-generic.em->ldelf*.c
changes.
v5: fix tabdamage. Drop #inclusions in .h files: include in .c files,
.em files, and use struct forwards instead. Use bfd_section_is_ctf
inline function rather than SECTION_IS_CTF macro. Move a few
comments.

This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

This patch deals with the generation of the import library on the fly.
The implementation is inefficient because the linker makes a lot of
calls to realloc and memmove when importing the symbols in order to
maintain a sorted list of symbols.
This is fixable by relying on the fact that, for every linked DLL,
the list of symbols it exports is already sorted so you can import
them en masse once you have found the insertion point.

This patch deals with the auto-import feature. There are 2 versions
of this feature: the original one, which was piggybacked on the OS
loader with an optional help from the runtime (--enable-auto-import
--enable-runtime-pseudo-reloc-v1) and is still the one mostly
documented in the sources and manual; the enhanced one by Kai Tietz,
which is entirely piggybacked on the runtime (--enable-auto-import
--enable-runtime-pseudo-reloc-v2) and is the default for Mingw and
Cygwin nowadays.
The implementation is inefficient because of pe[p]_find_data_imports:
for every undefined symbol, the function walks the entire set of
relocations for all the input files and does a direct name comparison
for each of them.
This is easily fixable by using a hash-based map for v1 and a simple
hash table for v2. This patch leaves v1 alone and only changes v2.
It also factors out pe[p]_find_data_imports into a common function,
removes old cruft left and right, and attempts to better separate
the implementations of v1 and v2 in the code.

This patch standardizes messages in ld, to better conform to the GNU
coding standard. Besides issues of capitalization and full-stops,
I've
- Split up help messages for target options, so that adding a new
option does not mean loss of translation for all the others.
- Embedded tabs have been removed, since a user might have tab stops
set at other than 8 char intervals.
- Added missing program name (%P). ld isn't the compiler.
- Put %F and %X first (and removed %X if %F was present). These can
go anywhere, but look silly in the m%Fiddle of a message, and
choosing "%P%F:" in some messages but "%F%P:" in others leads to the
likelihood of duplication in ld.pot. Besides, the colon belongs
with %P.

which the automatic generation of exported variables should be disabled.
In the latest git version of mingw-w64, one can set the default
libmsvcrt.a to actually be the import library of another CRT version,
to facilitate switching to ucrtbase.dll. In these versions, the
traditional libmsvcrt.a (for linking to msvcrt.dll) is also provided
with the name libmsvcrt-os.a.
The import libraries for the CRT also contain a number of compatibility
wrapper functions. The ones in libmsvcrt.a have so far been excluded
automatically since they in most cases come with a corresponding
__imp_foo function. None of these make sense to export automatically
from a DLL though, so add these libraries to the exclude list.
libucrtbase.a contains a number of compatibility wrapper functions
that don't have a corresponding __imp_foo symbol, which cause
these symbols to be exported from DLLs.
This can be worked around on the mingw-w64 side by adding extra
__imp_ symbols, but since they aren't strictly necessary for linking
to succeed, it's probably better long-term to add these libraries to
the exclusion list.

The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs. This
patch adds an "output_type" field:
enum output_type
{
type_unknown = 0,
type_executable,
type_dll,
type_relocatable
};
and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC. Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
