direct dispatch.

This completes the grand PPC file renaming

These are used to represent float and double values, and the two regclasses
contain the same physical registers.

llvm-svn: 23577

instructions take a consistent reg class.  Implement ISD::UNDEF in the dag->dag
selector to generate this, fixing UnitTests/2003-07-06-IntOverflow.

Remove the LoadHiAddr pseudo-instruction.
Optimization of stores to and loads from statics.
Force JIT to use new non-PIC codepaths.

static global variables whose addresses are taken.  This allows us to
convert the following code for taking the address of a static function foo

        addis r2, r30, ha16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")
        lwz r3, lo16(Ll1__2E_foo_2$non_lazy_ptr-"L00001$pb")(r2)

which also includes linker stub code emitted at the end of the .s file not
shown here, and replace it with this:

        addis r2, r30, ha16(l1__2E_foo_2-"L00001$pb")
        la r3, lo16(l1__2E_foo_2-"L00001$pb")(r2)

which in addition to not needing linker help, also has no load instruction.
For those not up on PowerPC mnemonics, la is shorthand for add immediate.

LLVM blocks as the keys for the branch rewriter.  This fixes treeadd and
many other programs with the JIT.

* Add relocations for refernces to non-lazy darwin stubs and implement
  them correctly.

With this change, we can correctly references external globals, and now
all but two UnitTests and all but 1 Regression/C tests pass.

More importantly, bugpoint-jit will start giving us useful testcases,
instead of always telling us that references to external globals don't
work :)

* Stop the confusion of using rv and Addr for global addresses: just use rv

llvm-svn: 17195

* Convert register numbers from their opcode value to the real value, e.g.
  PPC::R1 => 1 and PPC::F1 => 1
* Add correct handling of loading of global values which are PC-relative --
  implement ha16() and lo16()

llvm-svn: 17190

llvm-svn: 17151

llvm-svn: 17150

  including registers, constants, and partial support for global addresses
* The JIT is disabled by default to allow building llvm-gcc, which wants to test
  running programs during configure
