Krzysztof Parzyszek a8ab1b75cb [Hexagon] Add support for Hexagon V65 
llvm-svn: 320404

Krzysztof Parzyszek 8c53c95137 [Hexagon] Mark vector loads as predicable, update instruction mappings 
All loads of form V6_vL32b_{,cur,nt,tmp,nt_cur,nt_tmp}_{ai,pi,ppu} are
predicable on v62 (but not on v60). Mark them all as predicable in the
instruction definitions, and handle the v60 case in HII::isPredicable.

Krzysztof Parzyszek 557729761c [Hexagon] Switch to parameterized register classes for HVX 
This removes the duplicate HVX instruction set for the 128-byte mode.
Single instruction set now works for both modes (64- and 128-byte).

Krzysztof Parzyszek 9c084fc55d [Hexagon] Add intrinsics for data cache operations 
This is the LLVM part, adding definitions for
  void @llvm.hexagon.Y2.dccleana(i8*)
  void @llvm.hexagon.Y2.dccleaninva(i8*)
  void @llvm.hexagon.Y2.dcinva(i8*)
  void @llvm.hexagon.Y2.dczeroa(i8*)
  void @llvm.hexagon.Y4.l2fetch(i8*, i32)
  void @llvm.hexagon.Y5.l2fetch(i8*, i64)
The clang part will follow.

Krzysztof Parzyszek 4a1c3f0aaa [Hexagon] Replace CVI_VM_CUR_LD type with CVI_VM_LD 
A .cur instruction can be identified by checking isCVINew() && mayLoad().

Patch by Colin LeMahieu.

Krzysztof Parzyszek 058abf1a4a [Hexagon] Change the vector scaling for vector offsets 
Keep full offset value on MI-level instructions, but have it scaled down
in the MC-level instructions.
