Reduced:
```
struct {
int operator[](long);
} _boxWidths, _boxHeights;
bool _bboxesNormalized;
float _stepX, _stepY;
float *forward___trans_tmp_1, *forward_outputPtr;
void forward() {
float _boxWidth, _boxHeight;
_boxWidth = _boxWidths[0];
_boxHeight = _boxHeights[0];
for (int j; j; ++j) {
float center_x = 0 * _stepX, center_y = 0 * _stepY, imgHeight, imgWidth;
float *dst = forward_outputPtr;
if (_bboxesNormalized) {
dst[0] = dst[1] = (center_y - _boxHeight * 0.5f) / imgHeight;
dst[2] = (center_x + _boxWidth * 0.5f) / imgWidth;
dst[3] = (center_y + _boxHeight * 0.5f) / imgHeight;
} else
dst[2] = _boxWidth * 0.5f + _boxHeight * 0.5f;
forward___trans_tmp_1 = forward_outputPtr + 4;
forward_outputPtr = forward___trans_tmp_1;
}
}
