Dale Johannesen 6ca3ccf519 Rewrite tblgen handling of subtarget features so 
it follows the order of the enum, not alphabetical.
The motivation is to make -mattr=+ssse3,+sse41
select SSE41 as it ought to.  Added "ignored"
enum values of 0 to PPC and SPU to avoid compiler
warnings.

Dale Johannesen c5283ecd6f long double patch 2 of N. Handle it in TargetData. 
(I've tried to get the info right for all targets,
but I'm not expert on all of them - check yours.)

Nicolas Geoffray b3e99a18ee The PPC64 ELF ABI is "intended to use the same structure layout and calling convention rules 
as the 64-bit PowerOpen ABI" (Reference http://www.linux-foundation.org/spec/ELF/ppc64/).
Change all ELF tests to ELF32.

Bill Wendling c7b2ab9bdf Instead of yet another enum indicating the "assembly language flavor", 
just use the one that's in the subtarget.

Chris Lattner f4646a7e54 Another step forward in PPC64 JIT support: we now no-longer need stubs 
emitted for external globals in PPC64-JIT-PIC mode (which is good because
we didn't handle them before!).

This also fixes a bug handling the picbase delta, which we would get wrong
in some cases.

complete.

Chris Lattner 16682fff2b Document the subtarget features better, make sure that 64-bit mode, 64-bit 
support, and 64-bit register use are all consistent with each other.

Add a new "IsPPC" feature, to distinguish ppc32 vs ppc64 targets, use this
to configure TargetData differently.  This not makes ppc64 blow up on lots
of stuff :)

Chris Lattner a35f306740 Rename some subtarget features. A CPU now can *have* 64-bit instructions, 
can in 32-bit mode we can choose to optionally *use* 64-bit registers.

Chris Lattner 0c4aa14deb First baby step towards ppc64 support. This adds a new -march=ppc64 backend 
that is currently just like ppc32 :)

Chris Lattner b9f35f06bc Add a subtarget feature for the stfiwx instruction. I know the G5 has it, 
but I don't know what other PPC impls do.  If someone could update the proc
table, I would appreciate it :)

Nate Begeman e74dfbb9ce Do the right thing and enable 64 bit regs under the control of a subtarget 
option.  Currently the only way to enable this is to specify the
64bitregs mattr flag.  It is never enabled by default on any config yet.

Jim Laskey 19058c3989 1. Use SubtargetFeatures in llc/lli. 
2. Propagate feature "string" to all targets.

3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

Chris Lattner 983a415b6a Consolidate the GPOpt stuff to all use the Subtarget, instead of still 
depending on the command line option.  Now the command line option just
sets the subtarget as appropriate.  G5 opts will now default to on on
G5-enabled nightly testers among other machines.
