switch statements in the constructors and simplifies the
implementation of the getUseType() member function. You will have to
specify defs using MachineOperand::Def instead of MOTy::Def though
(similarly for Use and UseAndDef).

one terminator instruction in each basic block.

Also, make an assertion actually fireable!

AFTER the GEP that was emitted.  :(

(minor) benefits right now:

1. An extra dummy MOVrr32 is gone.  This move would often be coallesced by
   both allocators anyway.
2. The code now uses the gep_type_iterator to walk the gep, which should future
   proof it a bit.  It still assumes that array indexes are Longs though.

These don't really justify rewriting the code.  The big benefit will come later
though.

leave register operands with the same use/def flags as the original
instruction.

hot 164.gzip loop.

llvm-svn: 11702

This occurs in 164.gzip, as a result of it declaring arrays extern.

value is a physreg and one is a virtreg.  For this reason, disable copy folding
entirely for physregs.  Also, use the new isMoveInstr target hook which gives us
folding of FP moves as well.

llvm-svn: 11700

Also make it less aggressive as the current implementation breaks in
some cases.

FIX MAJOR BUG, whereby we didn't merge null edges correctly. Correcting this
fixes poolallocation on 175.vpr, and possibly others.

in a signal handler, allocating memory or doing other unsafe things is bad,
which means we should do it in a different process.

BU propagation, clone the globals into the GG of EACH FUNCTION that finishes
processing!  The GlobalsGraph *must* include all globals and effects from
all functions in the program.  Fixing this makes pool allocation work better
on 175.vpr, but it still ultimately crashes.

llvm-svn: 11686

end of the BU and CBU passes.  The globals will be marked incomplete, so it
doesn't matter if they are missing some info, and merging isn't guaranteed
to bring everything in anyway!
