Another nasty coalescer bug (is there another kind):
After coalescing reg1027's def and kill are both at the same point:
%reg1027,0.000000e+00 = [56,814:0) 0@70-(814)
bb5:
60 %reg1027<def> = t2MOVr %reg1027, 14, %reg0, %reg0
68 %reg1027<def> = t2LDRi12 %reg1027<kill>, 8, 14, %reg0
76 t2CMPzri %reg1038<kill,undef>, 0, 14, %reg0, %CPSR<imp-def>
84 %reg1027<def> = t2MOVr %reg1027, 14, %reg0, %reg0
96 t2Bcc mbb<bb5,0x2030910>, 1, %CPSR<kill>
Do not remove the kill marker on t2LDRi12.
