[cfe-dev] The Conditional Operator and Unused Results

[Justin Bogner]

I submitted [bug 8282], which is that statements like (x?y++:0) will
warn about an unused result for the 0. This idiom occurs in macros for
control flow, ie, in CPU_SET.

Currently, (x ? y : z) warns if either y or z would warn. Should this be
changed to warn only if both y and z would warn?
