|
// 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).

// 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.
