10 years agoFix the end location of init-capture annotations in ObjC++
Ben Langmuir [Thu, 30 Apr 2015 18:40:23 +0000 (18:40 +0000)]
Fix the end location of init-capture annotations in ObjC++

And thereby stop asserting.

In ObjC++ modes, we tentatively parse the lambda introducer twice: once
to disambiguate designators, which we also do in C++, and a second time
to disambiguate objc message expressions. During the second tentative
parse, the last cached token will be the annotation token we built in
the first parse. So use getLastLoc() to get the correct end location
for the rebuilt annotation.

Fix private constructor for ScaledNumber.

DigitsT. This was preventing instantiations of ScaledNumber with
anything other than uint64_t types.

In implementing the tests, I ran into another issue. Operators >>= and
<<= did not have variants for accepting other ScaledNumber as the shift
argument. This is expected by the SCALED_NUMBER_BOP.

It makes no sense to allow shifting a ScaledNumber by another
ScaledNumber, so the patch includes two new templates for shifting
ScaledNumbers.
