23cdb0bdcf DEBUG_VALUE is now variable sized, as it has a
target-dependent memory address representation in it.
Restore X86 printing of DEBUG_VALUE; lowering is
done in X86RegisterInfo using the normal algorithm.

3752d2fe34 Revert 93499. After discussion with Chris we agreed
FrameIndexes should be lowered, but the same way as
everything else (target dependent) rather than in a
special hacked way.  The lowering needs to be done
for eventual purposes of Dwarf generation.

71c25b7d7b Re-instate MOV64r0 and MOV16r0, with adjustments to work with the
new AsmPrinter. This is perhaps less elegant than describing them
in terms of MOV32r0 and subreg operations, but it allows the
current register to rematerialize them.

ad68264f59 Print out an informative comment for KILL instructions.
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

registers.

7cb384dcca devirtualize AsmPrinter::printBasicBlockLabel since it is never overridden.
Move GetMBBSymbol up to AsmPrinter and make printBasicBlockLabel use it so that

clients of printBasicBlockLabel can start using GetMBBSymbol instead.

e9434dbff4 X86MCInstLower::Lower should only not emit anything to OutStreamer,
this means that it can only lower one MachineInstr to one MCInst.  To
make this fly, we need to pull out handling of MO_GOT_ABSOLUTE_ADDRESS
(which generates an implicit label) out of X86MCInstLower.

more efficient SmallPtrSet<MCSymbol*>.  This eliminates string

c5ea263a23 remove DebugLoc from MCInst and eliminate "Comment printing" from
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

634cca377a hoist the call to processDebugLoc out of the generated
asm printer into the "printInstruction" routine.  This
fixes a problem where the experimental asmprinter would
drop debug labels in some cases, and fixes issues on ppc/xcore
where pseudo instructions like "mr" didn't get debug locs properly.

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.
