c045f38dcb Support printing base+offset pairs where the offset is a register. 
Use this for printing the jmpl indirect-call instruction.

8f9fb1d2ea Do not function resolve intrinsics. This prevents warnings and possible bad 
things from happening due to

declare bool %llvm.isunordered(double, double)
declare bool %llvm.isunordered(float, float)

9e1bbe86ba Codegen sub C, X a little bit better for register pressure. Instead of 
mov REG, C
sub REG, X

generate:

neg X
add X, C

which uses one less reg

d084a534a2 Support generating machine instructions for Phi nodes (based on x86, but with 
modifications for 1 LLVM BB --> many MBBs).
Fix store operand order: make it always be Base, Offset, SrcReg (think
"[ Base + Offset ] = SrcReg").
Rewrite visitBranchInst() to be even dumber (but working) -- give up on
the branch fallthrough trick, for the time being.
Make visitSetCondInst() work.

f815117481 Do not fold loads into instructions if it is used more than once. In particular 
we do not want to fold the load in cases like this:

  X = load
    = add A, X
    = add B, X

7d711d517b Use addGlobalAddress and addMBB for call & branch targets instead of addPCDisp. 
Abort if we see a PCRelativeDisp MachineOperand, to be safe. This matches
the X86 backend.

1b8f37597d Fix a recent regression in Applications/sgefa that Alkis pointed out to me. 
The vector may actually be empty if the register that we are marking as
recently used is not actually allocatable.  This happens for physical registers
that are not allocatable, like the ST(x) registers on X86.

a4353cabab Quick hack to get this file compiling again on Mac OS X. The right thing to do 
is write an autoconf macro that checks whether __isnan or isnan actually works
**using the C++ compiler after #include <cmath>**, instead of doing it the easy
way with AC_CHECK_FUNCS().
