ccd9796a46 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

09c1309814 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.

aebcce8404 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.

fda2cce3bf 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().

f6d023312f Add two options to the program:
-release causes ENABLE_OPTIMIZED=1 to be added to the make line so that
         the test runs against optimized code.
-pedantic causes the CompileOptimizeOpts variable to be overridden to
          add several additional warnings not picked up by -Wall. This
	  should help catch additional programming faux pas. See the diff
	  for the specific details.

01cdb1b367 By far, one of the most common uses of isnan is to make 'isunordered'
comparisons.  In an 'isunordered' predicate, which looks like this at
the LLVM level:

        %a = call bool %llvm.isnan(double %X)
        %b = call bool %llvm.isnan(double %Y)
        %COM = or bool %a, %b

We used to generate this code:

        fxch %ST(1)
        fucomip %ST(0), %ST(0)
        setp %AL
        fucomip %ST(0), %ST(0)
        setp %AH
        or %AL, %AH

With this patch, we generate this code:

        fucomip %ST(0), %ST(1)
        fstp %ST(0)
        setp %AL

Which should make alkis happy.  Tested as X86/compare_folding.llx:test1
