nesting level when computing it. Right now the allocator uses:

    w = sum_over_defs_uses( 10 ^ nesting level );

for live ranges that fall into assigned registers' holes.

Modified ReadArchiveBuffer() so that it dynamically allocates the
std::string object used to hold the bytecode object file's name.  This is
necessary because it is passed by reference to the new Module that is
allocated to represent the bytecode object, and previously we were
using a std::string that disappeared on function exit.

instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.

disable it.

Minor cleanups to killer pass

llvm-svn: 10555

llvm-svn: 10554

* Move sparc specific code out of generic code
* Eliminate the getOffset() method which made INVALID_FRAME_OFFSET
  necessary, which made pulling in MAX_INT as a sentinal necessary.

Also, add a stat for the number of globals emitted

VM.cpp and JIT.cpp files into JIT.cpp.  This also splits some nasty code out
into TargetSelect.cpp so that people hopefully won't notice it.  :)

more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:

        a = b op c

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.

killing instruction is tracked. This causes the LiveIntervals to
create bogus intervals. The workaound is to add a range to the
interval from the redefinition to the end of the basic block.

llvm-svn: 10510

Move some of the longer LiveIntervals::Interval method out of the
header and add debug information to them. Fix bug and simplify range
merging code.

AliasSetTracker as well.

a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.
