// Detect a number of compiler features - by compiler

// CATCH_CONFIG_COUNTER : is the __COUNTER__ macro supported?
Fixes for MinGW compatibility Some versions of MinGW do not support enough of Win32 API to let us work with SEH, so SEH is now MSVC only (+ configurable toggle). Also made use of gmtime_s MSVC only (as oposed to Windows only). Fixes #805

// CATCH_CONFIG_POSIX_SIGNALS : are POSIX signals supported?
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
2018-09-03 17:52:48 +02:00

Added unique_ptr detection to compiler_capabilities - as well as use by C++11 conformant compilers now enabled for VS2013 on too (see #479) - updated docs with this (and long long and override support)

Add missing catch_platform include to compiler capabilities This was removed in 64be2ad, to fix OS X approval tests. At the time I couldn't investigate because I didn't have access to OS X, but this fixed it (and since we don't have MinGW in CI, the breakage went unnoticed). As it turns out, piece-wise compilation of the Compact reporter had broken OS X detection for a long time, and fixing it was what broke the approvals. After the approval scripts were changed to compensate, this change passes approval tests and fixes

Provide a polyfill over `std::to_string` Android apparently does not support `std::to_string`, so we add a small polyfill over it. Right now only the ULP matcher uses it, but we have had plans to use it in `StringMaker<int>` and friends, as it performs a lot better than `std::stringstream` based stringification on MSVC.

Fixes for MinGW compatibility Some versions of MinGW do not support enough of Win32 API to let us work with SEH, so SEH is now MSVC only (+ configurable toggle). Also made use of gmtime_s MSVC only (as oposed to Windows only). Fixes #805

Provide a polyfill over `std::to_string` Android apparently does not support `std::to_string`, so we add a small polyfill over it. Right now only the ULP matcher uses it, but we have had plans to use it in `StringMaker<int>` and friends, as it performs a lot better than `std::stringstream` based stringification on MSVC. See #1280 for more details

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

Sweep out some extra warnings Swept: `-Wpadded` in some places (where it caused extra size, instead of just saying "hey, we padded struct at the end to align, just as standard says") `-Wweak-vtables` everywhere (Clang) `-Wexit-time-destructors` everywhere (Clang) `-Wmissing-noreturn` everywhere (Clang) The last three are enabled for Clang compilation going forward.

Add support for templated tests This adds support for templated tests and test methods via `TEMPLATE_TEST_CASE` and `TEMPLATE_TEST_CASE_METHOD` macros.
