Dale Johannesen 1ebb395cee Don't count debug info as instructions. This was
preventing the emission of the NOP on Darwin for a
function with no actual code.  From timberwolfmc
with TEST=optllcdbg.

Devang Patel 080e4fb2f0 Print variable scope name in DEBUG_VALUE comment. Useful in some cases. e.g.
##DEBUG_VALUE: runOnMachineFunction:this <- RDI+0
	##DEBUG_VALUE: runOnMachineFunction:fn <- RSI+0
	##DEBUG_VALUE: DeadDefs <- undef ## SimpleRegisterCoalescing.cpp:2706
	##DEBUG_VALUE: getRegInfo:this <- [%rsp+$56]+$0
	##DEBUG_VALUE: getTarget:this <- [%rsp+$56]+$0

Chris Lattner 08e9e72fa9 Rework global alignment computation again. Now we do round up
alignment of globals to the preferred alignment, but only when
there is no section specified on the global (by far the common
case).

ForcedAlignBits argument, tweaking the single client of it.

Chris Lattner 64d43d80be round zero-byte .zerofill directives up to 1 byte. This
should fix some "g++.dg-struct-layout-1" failures,

Chris Lattner 3af635a296 add a comment in verbose-asm mode indicating why a noop is being generated.

Chris Lattner 6a5e706e3c on darwin empty functions need to codegen into something of non-zero length,
otherwise labels get incorrectly merged.  We handled this by emitting a 
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes.  Handle this by emitting a noop.  This
is more gross than it should be because arm/ppc are not fully mc'ized yet.

This fixes rdar://7908505

Chris Lattner f740a8ceeb fix PR6921 a different way. Intead of increasing the
alignment of globals with a specified alignment, we fix
common variables to obey their alignment.  Add a comment
explaining why this behavior is important.

Chris Lattner 386a220f70 Fix PR6921: globals were not getting correctly rounded up to their
preferred alignment unless they were common or some other special
case.

Chris Lattner 5100367ff3 Bill's change in r95336 broke empty aggregates embedded
in other types.  fix this by only bumping zero-byte globals
up to a single byte if the *entire global* is zero size,
fixing PR6340.

This also fixes empty arrays etc to be handled correctly,
and only does this on subsection-via-symbols targets (aka
darwin) which is the only place where this matters.

Dale Johannesen 5d7f0a0fdd Move printing of target-indepedent DEBUG_VALUE comments
into AsmPrinter.  Target-dependent form is still generated
by FastISel and still handled in X86 code.

There is probably a more elegant way to do this.

Chris Lattner 4a4710a055 clean up the asmprinter interface a bit, rename a few
"Print" methods to "Emit".  Emit is something that goes
to an mc streamer, Print is something that goes to a
raw_ostream (for inline asm)

Chris Lattner d20699bc87 Momentous day: remove the "O" member from AsmPrinter. Now all
"asm printering" happens through MCStreamer.  This also 
Streamerizes PIC16 debug info, which escaped my attention.

This removes a leak from LLVMTargetMachine of the 'legacy'
output stream.

Chris Lattner 462720b1b6 now that all operand printing happens to specified streams, we can
print function level inline asm with EmitInlineAsm instead of writing
it directly to "O".
