Bug ID: 64276
Summary: would be better to use __cpp_exceptions rather than
__EXCEPTIONS to determine whether exceptions are
available
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: richard-gccbugzilla at metafoo dot co.uk
CC: redi at gcc dot gnu.org
libstdc++ uses __EXCEPTIONS to determine wither exceptions are available, and
uses __GXX_RTTI to determine if RTTI is available. __EXCEPTIONS is ambiguous;
it can mean either "generate cleanups on exception unwind paths" or "allow C++
exception handling syntax", and some compilers allow these flags to be set
independently. It would be more portable (and would set a better example) to
use __cpp_exceptions and __cpp_rtti rather than these macros, now that GCC
supports them.
