[LLVMdev] Thumb categorizing TST wrongly

[Gabor Greif]

I see strangeness on Thumb TST (tTST) predicate 'isCompare'

It is true for regular ARM, false for Thumb:

(gdb) p MI->dump()
   TSTri %reg16397, 3, pred:14, pred:%reg0, %CPSR<imp-def>; GPR:% 
reg16397
$24 = void
(gdb) p MI->getDesc().isCompare()
$25 = true


(gdb) p MI->dump()
   tTST %reg16396, %reg16397, pred:14, pred:%reg0, %CPSR<imp-def>;  
tGPR:%reg16396,16397
$22 = void
(gdb) p MI->getDesc().isCompare()
$23 = false


Is this intentional or just an oversight? In latter case how do I fix  
it? Tablegen input?

Thanks and cheers,
