llvm dev - May 2012 - [LLVMdev] Minor typo in source file ObjectFile.h

const uint64_t UnknownAddressOrSize
<http://llvm.org/doxygen/namespacellvm_1_1object.html#abcfa9b6f24c69c52d2489a102ba3583c>
= ~0ULL


This found at line 260 in ObjectFile.h.  Notice the 0ULL thingy.


Cheers,
Mikael

What do you find troubling about it?  It's simply a way to set all bits in
an unsigned variable.

Yes, you're absolutely right.

But the "problem" is that in Danish, my native language, zero is
spelled
and pronounced "nul".  So when I saw "0ULL", I immediately
jumped up the
chair, forgetting my brain somewhere, and thought: "Wow, there's
somebody
who meant to write NULL."  I thought the 0ULL was a misspelling of NULL.
(~NULL is not such a fortunate construct.)

I am deeply ashamed of myself for reporting this bogus error and I plan to
be much more cautious in the future.


Cheers,
Mikael
