Target/X86/Printer.cpp: Add sizePtr function, and use it instead of
" <SIZE> PTR " string when emitting assembly. Target/X86/X86InstrInfo.def: Tidy up a bit: Squashed everything down to 118 chars wide, wrapping lines so that comment is at the same point on each line. Rename "NoImpRegs" as "NoIR". (most instructions have NoImpRegs twice on a line, so this saves 10 columns). Also, annotate various instructions with flags for size of memory operand. (MemArg16, MemArg32, MemArg64, etc.) Target/X86/X86InstrInfo.h: Define flags for size of memory operand. (MemArg16, MemArg32, MemArg64, etc.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4932 91177308-0d34-0410-b5e6-96231b3b80d8
