* Cute bug fix: when moving links from N to this, some links could haveVikram S. Adve2002-12-051-14/+23

* Target/X86/Printer.cpp: Add sizePtr function, and use it instead ofBrian Gaeke2002-12-053-111/+143
| | | | | | | | | | | | | | | | | | " <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.) llvm-svn: 4932
