This one is a bit mysterious.. 128 / 0x80 is not in the RegisterId. Is the enum missing floating-point registers perhaps?

I guess it's FP0, from reading the comments in X86MCTargetDesc.cpp:

// The x87 registers start at 128 and are numbered sequentially.
unsigned FP0Start = 128;
for (unsigned I = 0; I < 8; ++I)
  MRI->mapLLVMRegToCVReg(X86::FP0 + I, FP0Start + I);

Looks like it came in with the PDB stuff in r270628.

Oh, I guess it's FP0. I'll see if I can add it to the enum in a follow-up.

These enumeration values are derived from the CV_HREG_e enumeration which is in cvconst.h

https://github.com/Microsoft/microsoft-pdb/blob/master/include/cvconst.h

In the followup, can you call them ST0, ST1, etc, to maintain naming consistency with the enumeration in cvconst?
