_5 = BIT_FIELD_REF <_1, 8, 0>;
_6 = _5 != 0;
_7 = _5 == 0;
_8 = (signed char) _7;
_9 = (signed char) _5;
_10 = _9 + -1;
It is the same.
>here only a target option impacts the behavior
Because -mgeneral-regs-only basically is -mno-sse which also shows the issue.
Basicaly is the lowering of the vector comparison (combined with the referenced
match pattern in the other bug report) which is causing the issue.
