Middle end is asking:
(gdb) up

/home/uros/git/gcc/gcc/combine.c:6938
6938 compare_mode = SELECT_CC_MODE (new_code, op0, op1);
(gdb) p new_code
$5 = LTGT
(gdb) p debug_rtx (op0)
(mem/c:SI (symbol_ref:DI ("e") [flags 0x2] <var_decl 0x7ffff7ffbd80 e>) [1 e+0
S4 A32])
$6 = void
(gdb) p debug_rtx (op1)
(mem/c:SI (symbol_ref:DI ("a") [flags 0x2] <var_decl 0x7ffff7ffbb40 a>) [1 a+0

$7 = void
