Daniel Dunbar 9abdc6cc3c TargetRegistry: Change AsmPrinter constructor to be typed as returning an 
AsmPrinter instance (instead of just a FunctionPass)

llvm-svn: 78962

Daniel Dunbar 95f58463e5 TargetRegistry: Reorganize AsmPrinter construction so that clients pass in the 
TargetAsmInfo. This eliminates a dependency on TargetMachine.h from
TargetRegistry.h, which technically was a layering violation.
 - Clients probably can only sensibly pass in the same TargetAsmInfo as the
   TargetMachine has, but there are only limited clients of this API.

Chris Lattner abdcbc7ef2 Change the asmprinter to print the comment character before the 
"inlineasmstart/end" strings so that the contents of the directive
are separate from the comment character.  This lets elf targets
get #APP/#NOAPP for free even if they don't use "#" as the comment
character.  This also allows hoisting the darwin stuff up to the
shared TAI class.

Daniel Dunbar c4f8ea4ccb Add 'isCodeGenOnly' bit to Instruction .td records. 
- Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

 - -2 FIXMEs.

like diving into the jumptable snarl just now.

Evan Cheng 3606467709 Fix Thumb2 load / store addressing mode matching code. Do not use so_reg form to 
match base only address, i.e. [r] since Thumb2 requires a offset register field.
For those, use [r + imm12] where the immediate is zero.
Note the generated assembly code does not look any different after the patch.
But the bug would have broken the JIT (if there is Thumb2 support) and it can
break later passes which expect the address mode to be well-formed.

Bob Wilson 12842f9865 Use vAny type to get rid of Neon intrinsics that differed only in whether 
the overloaded vector types allowed floating-point or integer vector elements.
Most of these operations actually depend on the element type, so bitcasting
was not an option.

If you include the vpadd intrinsics that I updated earlier, this gets rid
of 20 intrinsics.
