Hi,
N3639, which was voted into the C++14 committee draft today, adds a
std::bad_array_length exception which an implementation is required to
throw if the computed bound for a VLA ("array of runtime bound") is
"erroneous".
"erroneous" can be any of:
- bound <= 0
- bound > some implementation-defined limit
- bound < number of initializers provided
We need a new ABI entry point to throw this exception. I propose we don't
try to encode what went wrong and just use
extern "C" void __cxa_throw_bad_array_length();
analogously to __cxa_throw_bad_array_*new*_length.
Sound good?
