New Revision: 310427
URL: http://llvm.org/viewvc/llvm-project?rev=310427&view=rev
Log:
Sema: disable implicit conversion from _Complex to real types in C++.
Converting a _Complex type to a real one simply discards the imaginary part.
This can easily lead to loss of information so for safety (and GCC
compatibility) this patch disallows that when the conversion would be implicit.
The one exception is bool, which actually compares both real and imaginary
parts and so is safe.
