| /* This is a list of ISA extentsions in AArch64. |
| |
| 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. */ |
