ba4733d901 Remove what little AIX support we have. It has never been tested and isn't 
complete.

7c1fb5f08c 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 :)

a7a5854f1c 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.

94de9a8951 First baby step towards ppc64 support. This adds a new -march=ppc64 backend 
that is currently just like ppc32 :)

bf751e2d6f 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 :)

581a8f79bc Give full control of subtarget features over to table generated code.

9d2b817fcb 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.

21e463b2bf More PPC32 -> PPC changes, as well as merging some classes that were 
redundant after the change.

d401dff796 Add accessor for 64bit flag, so that we can tell when it is safe to 
generate the fun in-register fp<->long instructions.

1e9de3ed2d Decouple fsqrt from gpul optimizations, implementing fsqrt.ll. 
Remove the -enable-gpopt option which is subsumed by feature flags.

b1e1180ca0 1. Use SubtargetFeatures in llc/lli. 
2. Propagate feature "string" to all targets.

3. Implement use of SubtargetFeatures in PowerPCTargetSubtarget.

3c304a3ba1 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.
