0009 // Cray C++ compiler setup.
0010 //
0011 // There are a few parameters that affect the macros defined in this file:
0012 //
0013 // - What version of CCE (Cray Compiling Environment) are we running? This
0014 //   comes from the '_RELEASE_MAJOR', '_RELEASE_MINOR', and
0015 //   '_RELEASE_PATCHLEVEL' macros.
0016 // - What C++ standards conformance level are we using (e.g. '-h
0017 //   std=c++14')? This comes from the '__cplusplus' macro.
0018 // - Are we using GCC extensions ('-h gnu' or '-h nognu')? If we have '-h
0019 //   gnu' then CCE emulates GCC, and the macros '__GNUC__',
0020 //   '__GNUC_MINOR__', and '__GNUC_PATCHLEVEL__' are defined.
0021 //
0022 // This file is organized as follows:
0023 //
0024 // - Verify that the combination of parameters listed above is supported.
0025 //   If we have an unsupported combination, we abort with '#error'.
0026 // - Establish baseline values for all Boost macros.
0027 // - Apply changes to the baseline macros based on compiler version. These
0028 //   changes are cummulative so each version section only describes the
0029 //   changes since the previous version.
0030 //   - Within each version section, we may also apply changes based on
0031 //     other parameters (i.e. C++ standards conformance level and GCC
0032 //     extensions).
0033 //
0034 // To test changes to this file:
0035 //
0036 // ```
0037 // module load cce/8.6.5 # Pick the version you want to test.
0038 // cd boost/libs/config/test/all
0039 // b2 -j 8 toolset=cray cxxstd=03 cxxstd=11 cxxstd=14 cxxstd-dialect=gnu linkflags=-lrt
0040 // ```
0041 // Note: Using 'cxxstd-dialect=iso' is not supported at this time (the
0042 // tests run, but many tests fail).
0043 //
0044 // Note: 'linkflags=-lrt' is needed in Cray Linux Environment. Otherwise
0045 // you get an 'undefined reference to clock_gettime' error.
0046 //
0047 // Note: If a test '*_fail.cpp' file compiles, but fails to run, then it is
0048 // reported as a defect. However, this is not actually a defect. This is an
0049 // area where the test system is somewhat broken. Tests that are failing
0050 // because of this problem are noted in the comments.
0051 //
0052 // Pay attention to the macro definitions for the macros you wish to
0053 // modify. For example, only macros categorized as compiler macros should
0054 // appear in this file; platform macros should not appear in this file.
0055 // Also, some macros have to be defined to specific values; it is not
0056 // always enough to define or undefine a macro.
0057 //
0058 // Macro definitions are available in the source code at:
0059 //
0060 // `boost/libs/config/doc/html/boost_config/boost_macro_reference.html`
0061 //
0062 // Macro definitions are also available online at:
0063 //
0064 // http://www.boost.org/doc/libs/master/libs/config/doc/html/boost_config/boost_macro_reference.html
0065 //
0066 // Typically, if you enable a feature, and the tests pass, then you have
0067 // nothing to worry about. However, it's sometimes hard to figure out if a
0068 // disabled feature needs to stay disabled. To get a list of disabled
0069 // features, run 'b2' in 'boost/libs/config/checks'. These are the macros
0070 // you should pay attention to (in addition to macros that cause test
0071 // failures).

0075 ////
0076
0077 // In a developer build of the Cray compiler (i.e. a compiler built by a
0078 // Cray employee), the release patch level is reported as "x". This gives
0079 // versions that look like e.g. "8.6.x".
0080 //
0081 // To accomplish this, the the Cray compiler preprocessor inserts:
0082 //
0083 // #define _RELEASE_PATCHLEVEL x
0084 //
0085 // If we are using a developer build of the compiler, we want to use the
0086 // configuration macros for the most recent patch level of the release. To
0087 // accomplish this, we'll pretend that _RELEASE_PATCHLEVEL is 99.
0088 //
0089 // However, it's difficult to detect if _RELEASE_PATCHLEVEL is x. We must
0090 // consider that the x will be expanded if x is defined as a macro
0091 // elsewhere. For example, imagine if someone put "-D x=3" on the command
0092 // line, and _RELEASE_PATCHLEVEL is x. Then _RELEASE_PATCHLEVEL would
0093 // expand to 3, and we could not distinguish it from an actual
0094 // _RELEASE_PATCHLEVEL of 3. This problem only affects developer builds; in
0095 // production builds, _RELEASE_PATCHLEVEL is always an integer.
0096 //
0097 // IMPORTANT: In developer builds, if x is defined as a macro, you will get
0098 // an incorrect configuration. The behavior in this case is undefined.
0099 //
0100 // Even if x is not defined, we have to use some trickery to detect if
0101 // _RELEASE_PATCHLEVEL is x. First we define BOOST_CRAY_x to some arbitrary
0102 // magic value, 9867657. Then we use BOOST_CRAY_APPEND to append the
0103 // expanded value of _RELEASE_PATCHLEVEL to the string "BOOST_CRAY_".
0104 //
0105 // - If _RELEASE_PATCHLEVEL is undefined, we get "BOOST_CRAY_".
0106 // - If _RELEASE_PATCHLEVEL is 5, we get "BOOST_CRAY_5".
0107 // - If _RELEASE_PATCHLEVEL is x (and x is not defined) we get
0108 //   "BOOST_CRAY_x":
0109 //
0110 // Then we check if BOOST_CRAY_x is equal to the output of
0111 // BOOST_CRAY_APPEND. In other words, the output of BOOST_CRAY_APPEND is
0112 // treated as a macro name, and expanded again. If we can safely assume
0113 // that BOOST_CRAY_ is not a macro defined as our magic number, and
0114 // BOOST_CRAY_5 is not a macro defined as our magic number, then the only
0115 // way the equality test can pass is if _RELEASE_PATCHLEVEL expands to x.
0116 //
0117 // So, that is how we detect if we are using a developer build of the Cray
0118 // compiler.
