#ifndef TWOBLUECUBES_CATCH_ENFORCE_H_INCLUDED

#include "catch_common.h"
Add support for -fno-exceptions (or equivalent) This means * Adding new configuration toggle `CATCH_CONFIG_DISABLE_EXCEPTIONS` and a best-guess configuration auto-checking for it. * Adding new set of internal macros, `CATCH_TRY`, `CATCH_CATCH_ALL` and `CATCH_CATCH_ANON` that can be used in place of regular `try`, `catch(...)` and `catch(T const&)` respectively, while disappearing when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is enabled. * Replacing all uses of `throw` with calls to `Catch::throw_exception` customization point. * Providing a default implementation for the above customization point when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is set. * Letting users override this implementation with their own. * Some minor changes and ifdefs all around to support the above

#include "catch_compiler_capabilities.h"
Introduced ReusableStringStream and removed all uses of std::ostringstream from the main path ReusableStringStream holds a std::ostringstream internally, but only exposes the ostream interface. It caches a pool of ostringstreams in a vector which is currently global, but will be made thread-local. Altogether this should enable both runtime and compile-time benefits. although more work is needed to realise the compile time opportunities.

Split out internal error macros from the common path
2017-08-01 18:46:33 +02:00
Introduce stubs for throwing specific exception types This allows us to move <stdexcept> out of the common path, and replace it with just <exception>. The difference between these two headers is ~13k lines after preprocessing on libstdc++ (16k vs 3k) and ~17k lines for MS's STL(33k vs 16k). Note that this is only beneficial if no other stdlib header we use includes <stdexcept>. AFAIK this is true for the newest MS's STL, but I have no idea of the applicability for libstdc++ and libc++.
