Anton Korobeynikov 2522908653 Materialize global addresses via movt/movw pair, this is always better 
than doing the same via constpool:
1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2.
2. Load from constpool might stall up to 300 cycles due to cache miss.
3. Movt/movw does not use load/store unit.
4. Less constpool entries => better compiler performance.

This is only enabled on ELF systems, since darwin does not have needed
relocations (yet).

by creating TargetConstants during instruction selection instead of during
legalization.

Bob Wilson 3b51560ae4 Revise ARM inline assembly memory operands to require the memory address to 
be in a register.  The previous use of ARM address mode 2 was completely
arbitrary and inappropriate for Thumb.  Radar 7137468.

Bob Wilson 2dd957fff6 Pass the optimization level when constructing the ARM instruction selector. 
Otherwise, it is always set to "default", which prevents debug info from
even being generated during isel.  Radar 7250345.

Anton Korobeynikov 7c2b1e71c1 Use movt/movw pair to materialize 32 bit constants on ARMv6T2+. 
This should be better than single load from constpool.

 2009-09-27 23:52:58 +00:00
Dan Gohman 32f71d714b Rename getTargetNode to getMachineNode, for consistency with the 
naming scheme used in SelectionDAG, where there are multiple kinds
of "target" nodes, but "machine" nodes are nodes which represent
a MachineInstr.

Bob Wilson e0636a7aed Remove unneeded ARM-specific DAG nodes for VLD* and VST* Neon operations. 
The instructions can be selected directly from the intrinsics.  We will need
to add some ARM-specific nodes for VLD/VST of 3 and 4 128-bit vectors, but
those are not yet implemented.
