Chris Lattner 0c6db524d6 Fix lowering to work correctly
llvm-svn: 14134

Chris Lattner 8f69c9e439 I misled Alkis: LLVM should have isnan, not isunordered.
isunordered(X, Y) === isnan(X) | isnan(Y)

Remove isunordered, add isnan.

Alkis Evlogimenos d0b5d0c7cc Add the isunordered intrinsic.

Chris Lattner 0d63958706 Remove an unused variable.
Work around for bogus errors: no those static functions don't need to
be executed to be initialized!

Chris Lattner 303ca1e509 By default, llvm.setjmp/llvm.longjmp intrinsics get lowered to their libc counterparts

Chris Lattner 25530a12a1 Refactor code. Now the intrinsic lowering pass tries to recycle preexisting
prototypes, even if they don't precisely match what it would prefer to use.
This fixes: CBackend/2004-02-15-PreexistingExternals.llx compiling it into:

  ltmp_0_30 = memcpy(l14_C, 4u, 17);
  ltmp_1_30 = memcpy(((int *)l27_A), ((unsigned )(long)l27_B), ((int )123u));

instead of:

  ltmp_0_30 = memcpy(l14_C, 4u, 17);
  ltmp_1_27 = l43_memcpy(l27_A, l27_B, 123u);

Which does the wrong thing as you could imagine.

Chris Lattner 0c48a03374 A target that doesn't support these intrinsics will still meet spec (the
intrinsic will always produce zero), but it will behave unexpectedly, so
warn like GCC does.

Chris Lattner 2d6902b4b6 Hrm, apparently I missed lowering this intrinsic. :(

Chris Lattner 3d903f0c0b Add VMCore and code generator support for debugging intrinsics. By default
code generators completely ignore them.

Chris Lattner 5d236005b0 Clean up a lot of the code I added yesterday by exposing the IntrinsicLowering
implementation from the TargetMachine directly.
