doing global variable classification anymore) and hookized, sink almost all target targets global variable emission code into AsmPrinter and out of each target. Some notes: 1. PIC16 does completely custom and crazy stuff, so it is not changed. 2. XCore has some custom handling for extra directives. I'll look at it next. 3. This switches linux/ppc to use .globl instead of .global. If .globl is actually wrong, let me know and I'll fix it. 4. This makes linux/ppc get a lot of random cases right which were obviously wrong before, it is probably now a bit healthier. 5. Blackfin will probably start getting .comm and other things that it didn't before. If this is undesirable, it should explicitly opt out of these things by clearing the relevant fields of MCAsmInfo. This leads to a nice diffstat: 14 files changed, 127 insertions(+), 830 deletions(-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93858 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
