| // Cray C++ compiler setup. |
| // |
| // There are a few parameters that affect the macros defined in this file: |
| // |
| // - What version of CCE (Cray Compiling Environment) are we running? 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. |
