This // comes from the '_RELEASE_MAJOR', '_RELEASE_MINOR', and // '_RELEASE_PATCHLEVEL' macros. // - What C++ standards conformance level are we using (e.g. '-h // std=c++14')? This comes from the '__cplusplus' macro. // - Are we using GCC extensions ('-h gnu' or '-h nognu')? If we have '-h // gnu' then CCE emulates GCC, and the macros '__GNUC__', // '__GNUC_MINOR__', and '__GNUC_PATCHLEVEL__' are defined. // // This file is organized as follows: // // - Verify that the combination of parameters listed above is supported. // If we have an unsupported combination, we abort with '#error'. // - Establish baseline values for all Boost macros. // - Apply changes to the baseline macros based on compiler version. These // changes are cummulative so each version section only describes the // changes since the previous version. // - Within each version section, we may also apply changes based on // other parameters (i.e. C++ standards conformance level and GCC // extensions). // // To test changes to this file: // // ``` // module load cce/8.6.5 # Pick the version you want to test. // cd boost/libs/config/test/all // b2 -j 8 toolset=cray cxxstd=03 cxxstd=11 cxxstd=14 cxxstd-dialect=gnu linkflags=-lrt // ``` // Note: Using 'cxxstd-dialect=iso' is not supported at this time (the // tests run, but many tests fail). // // Note: 'linkflags=-lrt' is needed in Cray Linux Environment. Otherwise // you get an 'undefined reference to clock_gettime' error. // // Note: If a test '*_fail.cpp' file compiles, but fails to run, then it is // reported as a defect. However, this is not actually a defect. This is an // area where the test system is somewhat broken. Tests that are failing // because of this problem are noted in the comments. // // Pay attention to the macro definitions for the macros you wish to // modify. For example, only macros categorized as compiler macros should // appear in this file; platform macros should not appear in this file. // Also, some macros have to be defined to specific values; it is not // always enough to define or undefine a macro. // // Macro definitions are available in the source code at: // // `boost/libs/config/doc/html/boost_config/boost_macro_reference.html` // // Macro definitions are also available online at: // // http://www.boost.org/doc/libs/master/libs/config/doc/html/boost_config/boost_macro_reference.html // // Typically, if you enable a feature, and the tests pass, then you have // nothing to worry about. However, it's sometimes hard to figure out if a // disabled feature needs to stay disabled. To get a list of disabled // features, run 'b2' in 'boost/libs/config/checks'. These are the macros // you should pay attention to (in addition to macros that cause test // failures). //// //// Front matter //// // In a developer build of the Cray compiler (i.e. a compiler built by a // Cray employee), the release patch level is reported as "x". This gives // versions that look like e.g. "8.6.x". // // To accomplish this, the the Cray compiler preprocessor inserts: // // #define _RELEASE_PATCHLEVEL x // // If we are using a developer build of the compiler, we want to use the // configuration macros for the most recent patch level of the release. To // accomplish this, we'll pretend that _RELEASE_PATCHLEVEL is 99. // // However, it's difficult to detect if _RELEASE_PATCHLEVEL is x. We must // consider that the x will be expanded if x is defined as a macro // elsewhere. For example, imagine if someone put "-D x=3" on the command // line, and _RELEASE_PATCHLEVEL is x. Then _RELEASE_PATCHLEVEL would // expand to 3, and we could not distinguish it from an actual // _RELEASE_PATCHLEVEL of 3. This problem only affects developer builds; in // production builds, _RELEASE_PATCHLEVEL is always an integer. // // IMPORTANT: In developer builds, if x is defined as a macro, you will get // an incorrect configuration. The behavior in this case is undefined. // // Even if x is not defined, we have to use some trickery to detect if // _RELEASE_PATCHLEVEL is x. First we define BOOST_CRAY_x to some arbitrary // magic value, 9867657. Then we use BOOST_CRAY_APPEND to append the // expanded value of _RELEASE_PATCHLEVEL to the string "BOOST_CRAY_". // // - If _RELEASE_PATCHLEVEL is undefined, we get "BOOST_CRAY_". // - If _RELEASE_PATCHLEVEL is 5, we get "BOOST_CRAY_5". // - If _RELEASE_PATCHLEVEL is x (and x is not defined) we get // "BOOST_CRAY_x": // // Then we check if BOOST_CRAY_x is equal to the output of // BOOST_CRAY_APPEND. In other words, the output of BOOST_CRAY_APPEND is // treated as a macro name, and expanded again. If we can safely assume // that BOOST_CRAY_ is not a macro defined as our magic number, and // BOOST_CRAY_5 is not a macro defined as our magic number, then the only // way the equality test can pass is if _RELEASE_PATCHLEVEL expands to x. // // So, that is how we detect if we are using a developer build of the Cray // compiler. #define BOOST_CRAY_x 9867657 // Arbitrary number #define BOOST_CRAY_APPEND(MACRO) BOOST_CRAY_APPEND_INTERNAL(MACRO) #define BOOST_CRAY_APPEND_INTERNAL(MACRO) BOOST_CRAY_##MACRO #if BOOST_CRAY_x == BOOST_CRAY_APPEND(_RELEASE_PATCHLEVEL) // This is a developer build. // // - _RELEASE_PATCHLEVEL is defined as x, and x is not defined as a macro. // Pretend _RELEASE_PATCHLEVEL is 99, so we get the configuration for the // most recent patch level in this release. #define BOOST_CRAY_VERSION (_RELEASE_MAJOR * 10000 + _RELEASE_MINOR * 100 + 99) #else // This is a production build. // // _RELEASE_PATCHLEVEL is not defined as x, or x is defined as a macro. #define BOOST_CRAY_VERSION (_RELEASE_MAJOR * 10000 + _RELEASE_MINOR * 100 + _RELEASE_PATCHLEVEL) #endif // BOOST_CRAY_x == BOOST_CRAY_APPEND(_RELEASE_PATCHLEVEL) #undef BOOST_CRAY_APPEND_INTERNAL #undef BOOST_CRAY_APPEND #undef BOOST_CRAY_x #ifdef __GNUC__ # define BOOST_GCC_VERSION (__GNUC__ * 10000 + __GNUC_MINOR__ * 100 + __GNUC_PATCHLEVEL__) #endif #ifndef BOOST_COMPILER # define BOOST_COMPILER "Cray C++ version " BOOST_STRINGIZE(_RELEASE_MAJOR) "."
