single object format can be shared.
This also adds support for
mov zed+(bar-foo), %eax
on ELF and COFF targets.

Added ARM specific ELF section types.
Added AttributesSection to ARMElfTargetObject
First step in unifying .cpu assembly tag with ELF/.o
llc now asserts on actual ELF emission on -filetype=obj :-)

they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
named. Since it is just a predicate and isn't actually changing any state.
2) Added a missing return in the comments for setCurrentDwarfLoc() in
include/llvm/MC/MCContext.h for fix formatting.
3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
state.
4) Simplified the last test in isValidDwarfFileNumber() to just a one line
boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.

time. That way, the EntrySize field is initialized for other code paths,
namely, the .ll -> .o code path.

resolved or not. Different object files have different restrictions and
different native assemblers have different idiosyncrasies we want to emulate
for now.
Move the existing MachO logic to the new place and implement an ELF one that
gets fixups to globals right.

new VariantKind to the MCSymbolExpr seems like overkill, but I'm not sure
there's a more straightforward way to get the printing difference captured.
(i.e., x86 uses @PLT, ARM uses (PLT)).

The ELF implementation now creates text, data and bss to match the gnu as
behavior.
The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.
A nice benefit is that -n is not required anymore when producing
ELF files.

VFP instructions use it for loading some constants, so implement that
handling.
Not thrilled with adding a member to MCOperand, but not sure there's much of
a better option that's not pretty fragile (like putting a double in the
union instead and just assuming that's good enough). Suggestions welcome...

the end of the line on a parser error, allowing skipping to happen
for syntactic errors but not for semantic errors. Before we would
miss emitting a diagnostic about the second line, because we skipped
it due to the semantic error on the first line:
foo %eax
bar %al
This fixes rdar://8414033 - llvm-mc ignores lines after an invalid instruction mnemonic errors

and output the dwarf line number tables. This takes the current loc info after
an instruction is assembled and saves the needed info into an object that has
vector and for each section. These objects will be used for the final patch to
build and emit the encoded dwarf line number tables. Again for now this is only
in the Mach-O streamer but at some point will move to a more generic place.

needed parsing for the .loc directive and saves the current info from that
into the context. The next patch will take the current loc info after an
instruction is assembled and save that info into a vector for each section for
use to build the line number tables. The patch after that will encode the info
from those vectors into the output file as the dwarf line tables.

Introduce a helper method to add a section to the end of a layout. This
will be used by the ELF ObjectWriter code to add the metadata sections
(symbol table, etc) to the end of an object file.
