r189416 changed the order of command line options shown in help message,
so the test needs adjusting.

With this patch the entry symbol is treated as an undefined symbol, to force
the resolver to resolve the entry symbol.

This should have been done in r187823 when I renamed LinkingContext
from TargetInfo. I missed a few files.

llvm-svn: 189267

The cleanup includes :-

* Rename ambiguous Header class to ELFHeader
* Convert Chunk contentype and kind to be a enumerated class
* Remove functions that are not being used, avoids future confusion

This change processes fini_array section in addition to processing
init_array sections. This also makes functions registered at compile
time for initialization and finalization to be run during execution

llvm-svn: 189196

This completes the subsystem name parsing to support the identifiers that the
Microsoft link.exe linker supports.  "windows" and "console" are left as the
first items as they are the expected common paths.

The debug flag being checked for seems to be controlled by whether the
build is asserts/non-asserts rather than debug/non-debug. Mostly these
correlate, but not necessarily.

As far as I can tell with various combinations of debug/assetions this
change makes no difference on autotools builds, but fixes a check-all
failure with CMake.

There may be relocations that may be pointing to the section
even if the section sizes are 0. We shouldnot ignore them
for that regard.

llvm-svn: 189139

There is no change in functionality, this uses the defined way to access
the relocation section that belongs to a particular section.

typeTLV content type is used by Darwin to represent thread local
storage. A new contentType has to be made to represent ELF
thread local storage data. These have been set to

- typeThreadZeroFill (represents TBSS storage)
- typeThreadData     (represents TDATA storage)

llvm-svn: 189137

BSS atoms dont take any file space in the Input file. They are associated
with a contentType(typeZeroFill). Similiar zero fill types also exist which
have the same meaning in terms of occupying file space in the Input.

These atoms have to be handled seperately when writing to the
lld's intermediate file or the lld test infrastructure.

Also adds a test.

Previously, the CMake build would look for llvm-tblgen to determine
if a directory is an LLVM build or install directory. Since we don't
want to include llvm-tblgen in the install, look for llvm-config instead,
and use that to find llvm-tblgen.

(This is the lld equivalent of Clang r189127.)

This used to be handled automagically by the option parsing library,
but after LLVM r188314, we should handle it ourselves.

No functionality change, but adds a test.

This is a temporary measure because the semantics of the common symbol is
actually more compilcated than the simple mergeable symbol.

llvm-svn: 188235

Patch by Ron Ofir.

llvm-svn: 188187

The import name is not always the same as the symbol name. If the name/type
field in the import header is NOPREFIX or UNDECORATE, we need to strip some
characters from symbol to get its import name.

The Microsoft PE/COFF spec is vague if symbol contains more than two
consecutive characters to be stripped. We used to strip all characters,
but it doesn't seem right as we couldn't link against the system library
because of this name mangling. Looks like we shouldn't strip more than one
character.
