Before using #include to read this file, define a macro: AARCH64_OPT_EXTENSION(EXT_NAME, FLAG_CANONICAL, FLAGS_ON, FLAGS_OFF, FEATURE_STRING) EXT_NAME is the name of the extension, represented as a string constant. FLAGS_CANONICAL is the canonical internal name for this flag. FLAGS_ON are the bitwise-or of the features that enabling the extension adds, or zero if enabling this extension has no effect on other features. FLAGS_OFF are the bitwise-or of the features that disabling the extension removes, or zero if disabling this extension has no effect on other features. FEAT_STRING is a string containing the entries in the 'Features' field of /proc/cpuinfo on a GNU/Linux system that correspond to this architecture extension being available. Sometimes multiple entries are needed to enable the extension (for example, the 'crypto' extension depends on four entries: aes, pmull, sha1, sha2 being present). In that case this field should contain a space (" ") separated list of the strings in 'Features' that are required. Their order is not important. */ /* Enabling "fp" just enables "fp".
