It seems that the block location of block 2 is incorect, the gcno shows block 2
is located in line 1 and line 5, but actually it is located in line 1 and line
3 as block 2 maps to source code c>='A' only?
int foo (char c)
{
int iftmp.0;
int D.2744;
int iftmp.0_1;
int iftmp.0_3;
int iftmp.0_4;
int _5;
<bb 2> :
if (c_2(D) > 64)
goto <bb 3>; [INV]
else
goto <bb 4>; [INV]
<bb 3> :
if (c_2(D) <= 90)
goto <bb 8>; [INV]
else
goto <bb 4>; [INV]
<bb 4> :
if (c_2(D) > 96)
goto <bb 5>; [INV]
else
goto <bb 6>; [INV]
