New Revision: 174968
URL: http://llvm.org/viewvc/llvm-project?rev=174968&view=rev
Log:
[NVPTX] Disable vector registers
Vectors were being manually scalarized by the backend. Instead,
let the target-independent code do all of the work. The manual
scalarization was from a time before good target-independent support
for scalarization in LLVM. However, this forces us to specially-handle
vector loads and stores, which we can turn into PTX instructions that
produce/consume multiple operands.

-// This pass converts operations on vector types to operations on their

-//
-// For generic binary and unary vector instructions, the conversion is simple.
-// Suppose we have
-// av = bv Vop cv
-// where av, bv, and cv are vector virtual registers, and Vop is a vector op.
-// This gets converted to the following :
-// a1 = b1 Sop c1
-// a2 = b2 Sop c2
-//
-// VectorToScalarMap maintains the vector vreg to scalar vreg mapping.
-// For the above example, the map will look as follows:
-// av => [a1, a2]
-// bv => [b1, b2]
-//
-// In addition, initVectorInfo creates the following opcode->opcode map.
-// Vop => Sop
-// OtherVop => OtherSop
-// ...
-//
-// For vector specific instructions like vecbuild, vecshuffle etc, the
-// conversion is different. Look at comments near the functions with
