[LLVMdev] BasicBlock.h in the binary and in the source differ

[mats petersson]

Looks like natural evolution to me - I'm pretty sure there was a
commit of that kind not that long ago.

One of the "positive" things with LLVM/Clang is that there is no
desire to keep interfaces stable. Sure that has the drawback that
sometimes you have to change your code that uses the interfaces, but
it also allows improvements that would be very hard to achieve if you
retain "must be backwards and forwards compatible for at least X units
of time".
