a full 64-bit address, it must be adjusted to fit in the branch instruction's
immediate field. (This is only used in the reoptimizer, for now.)

constant pool member's name.
This is intended to address Bug 333.
Also, fix an anachronistic usage of "M" as a parameter of type Function *.

Include SparcV9RegisterInfo.h.
Add a getRegisterInfo() accessor and SparcV9RegisterInfo instance, just like
on the X86 target.

functions for now). This automatically turns on the printing of machine
registers using their own real names, instead of goofy things like %mreg(42),
and allows us to migrate code incrementally to the new interface as we see fit.
The register file description it uses is hand-written, so that the register
numbers will match the ones that the SparcV9 target already uses.
Perhaps someday we'll tablegen it.

This prepares us to be able to de-virtualize and de-abstract it, and
take the register allocator bits out and move them into the register allocator
proper...

documentation that this module needs to be made independent of the
register file description of the current target.

of IntCC, FloatCC, and Special types.
Make SparcV9RegInfo::getRegClassIDOfRegType() return the right answer
if you ask for the class corresponding to SpecialRegType.

you would walk off the end of the FloatCCRegName array.

have non-long indices for sequential types. In order to avoid trying to figure
out how the v9 backend works, we'll just hack it in the preselection pass.

Move lowerselect pass to come after preselection. Move machine
code construction and stack slots pass to come right before instruction
selection. This is to help fix perlbmk.
Update comments.
Make the sequence of passes in addPassesToJITCompile look more like
the sequence of passes in addPassesToEmitAssembly, including support
for -print-machineinstrs.

Otherwise, if you're in debugging mode, you get warnings for (apparently)
every immediate constant in the function during reg. allocation.

Make an explicit call to it from runOnFunction() if we know we're supposed to
write into the global. This is lame (esp. the const_cast), but it solves
the problem.

make the output more compact.
Divorce state-saving from the doFinalization method; for some reason it's not
getting called when I want it to, at Reoptimizer time. Put the guts in
PhyRegAlloc::finishSavingState(). Put an abort() in it so that I can be really
really sure that it's getting called.

De-constify SaveStateToModule; we have to set both it and SaveRegAllocState
explicitly in the reoptimizer.
Make SaveRegAllocState an 'external location' option.
