/* This is a list of ISA extentsions in AArch64.
Before using #include to read this file, define a macro:
AARCH64_OPT_EXTENSION(EXT_NAME, FLAGS_ON, FLAGS_OFF, FEATURE_STRING)
EXT_NAME is the name of the extension, represented as a string constant.
FLAGS_ON are the bitwise-or of the features that the extension adds.
FLAGS_OFF are the bitwise-or of the features that the extension removes.
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 whitespace-separated list of the strings in 'Features'
that are required. Their order is not important. */
