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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8 |

*** add gcc builtins for alpha instructions *** custom expand byteswap into nifty extract/insert/mask byte/word/longword/quadword low/high sequences *** see if any of the extract/insert/mask operations can be added *** match more interesting things for cmovlbc cmovlbs (move if low bit clear/set) *** lower srem and urem remq(i,j): i - (j * divq(i,j)) if j != 0 remqu(i,j): i - (j * divqu(i,j)) if j != 0 reml(i,j): i - (j * divl(i,j)) if j != 0 remlu(i,j): i - (j * divlu(i,j)) if j != 0 *** add crazy vector instructions (MVI): (MIN|MAX)(U|S)(B8|W4) min and max, signed and unsigned, byte and word PKWB, UNPKBW pack/unpack word to byte PKLB UNPKBL pack/unpack long to byte PERR pixel error (sum accross bytes of bytewise abs(i8v8 a - i8v8 b)) cmpbytes bytewise cmpeq of i8v8 a and i8v8 b (not part of MVI extentions) this has some good examples for other operations that can be synthesised well from these rather meager vector ops (such as saturating add). http://www.alphalinux.org/docs/MVI-full.html
