There must be an issue with the sim value as we already should be handing
that.
```
#ifdef ARCH_BIG_ENDIAN
saved = temp = (int32_t) nxflat_swap32(*target);
#else
saved = temp = *target;
#endif
/* Mask and sign extend */
temp &= how_to->src_mask;
temp <<= (32 - how_to->bitsize);
temp >>= (32 - how_to->bitsize);
/* Offset */
temp += (sym_value + rel_section->vma) >> how_to->rightshift;
/* Mask upper bits from rollover */
temp &= how_to->dst_mask;
/* Replace data that was masked */
temp |= saved & (~how_to->dst_mask);
```
And from the very verbose debug output from ldnxflat
```
