[lld] Use %u instead of %d for uint32_t formatting

Authored by hughbe on Jan 22 2017, 11:36 AM.



StringTableOff is a uint32_t. However, here, we print it as a signed decimal (%d), which is wrong.

Neither is correct. It should be casted either to uintmax_t and printed with %ju or PRIu32 be used. The fancy new formatting system might also work of course, but won't give you a C string.
That said, this should also be changed to use snprintf...

I'd probably just cast to unsigned long and use lu. Using sprintf with (size_t)COFF::NameSize is indeed better.

Use snprintf

I assume you made a typo in your comment @ruiu, and meant snprintf

Sorry for updating after you approved, I didn't notice!

Still LGTM. Please run the tests and submit.
