They go into a code path that +// implements Feature F, and will log the proper error/warning messages. Parsing +// will then always continue as if the tested feature was enabled. +// +// There is typically no if-testing or conditional parsing, just insertion of the calls above. +// However, if symbols specific to the extension are added (step 5), they will +// only be added under tests that the minimum version and profile are present. +// +// 1) Add a symbol name for the extension string at the bottom of Versions.h: +// +// const char* const XXX_extension_X = "XXX_extension_X"; +// +// 2) Add extension initialization to TParseVersions::initializeExtensionBehavior(), +// the first function below: +// +// extensionBehavior[XXX_extension_X] = EBhDisable; +// +// 3) Add any preprocessor directives etc. in the next function, TParseVersions::getPreamble(): +// +// "#define XXX_extension_X 1\n" +// +// The new-line is important, as that ends preprocess tokens. +// +// 4) Insert a profile check in the feature's path (unless all profiles support the feature, +// for some version level). That is, call requireProfile() to constrain the profiles, e.g.: +// +// // ... in a path specific to Feature F... +// requireProfile(loc, +// ECoreProfile | ECompatibilityProfile, +// "Feature F"); +// +// 5) For each profile that supports the feature, insert version/extension checks: +// +// The mostly likely scenario is that Feature F can only be used with a +// particular profile if XXX_extension_X is present or the version is +// high enough that the core specification already incorporated it. +// +// // following the requireProfile() call... +// profileRequires(loc, +// ECoreProfile | ECompatibilityProfile, +// 420, // 0 if no version incorporated the feature into the core spec. +// XXX_extension_X, // can be a list of extensions that all add the feature +// "Feature F Description"); +// +// This allows the feature if either A) one of the extensions is enabled or +// B) the version is high enough. If no version yet incorporates the feature +// into core, pass in 0. +// +// This can be called multiple times, if different profiles support the +// feature starting at different version numbers or with different +// extensions. +// +// This must be called for each profile allowed by the initial call to requireProfile(). +// +// Profiles are all masks, which can be "or"-ed together. +// +// ENoProfile +// ECoreProfile +// ECompatibilityProfile +// EEsProfile +// +// The ENoProfile profile is only for desktop, before profiles showed up in version 150; +// All other #version with no profile default to either es or core, and so have profiles. +// +// You can select all but a particular profile using ~.
