are represented as "weak", but there are subtle differences in some cases on Darwin, so we need both. The intent is that "common" will behave identically to "weak" unless somebody changes their target to do something else. No functional change as yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51118 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
