Before using #include to read this file, define a macro:
- AARCH64_OPT_EXTENSION(EXT_NAME, FLAG_CANONICAL, FLAGS_ON, FLAGS_OFF,
- SYNTHETIC, 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.
- - SYNTHETIC is a boolean to indicate whether the option is a purely synthetic
- grouping of options and that the option itself has no feature bit (e.g.
- crypto). This is used to determine when sum of the individual options in
- FLAGS_ON can be replaced by FLAG_CANONICAL in options minimization. If the
- group is synthetic then they can be replaced when all options in FLAGS_ON
- are enabled, otherwise they can only be replaced when
- FLAGS_ON | FLAG_CANONICAL are enabled.
+ AARCH64_OPT_EXTENSION(NAME, IDENT, REQUIRES, EXPLICIT_ON,
+ EXPLICIT_OFF, FEATURE_STRING)
+
+ - NAME is the name of the extension, represented as a string constant.
+
+ - IDENT is the canonical internal name for this flag.
+
+ - REQUIRES is a list of features that must be enabled whenever this
+ feature is enabled. The relationship is implicitly transitive:
+ if A appears in B's REQUIRES and B appears in C's REQUIRES then
+ A and B must be enabled whenever C is. Thus, turning on C also
+ turns on A and B, while turning off A or B also turns off C.
+
+ - EXPLICIT_ON is a list of features that are enabled by an explicit
+ +NAME specification, in addition to those listed in REQUIRES.
+ Usually this is an empty list; comments below explain the exceptions.
+ The list is implicitly transitively closed wrt REQUIRES (but *not*
+ to EXPLICIT_ON, since NAME is the only thing explicit in +NAME).
+ Thus if A is in B's REQUIRES and B is in C's EXPLICIT_ON, +C will
+ enable both B and A. B's EXPLICIT_ON has no effect on +C.
+
+ - EXPLICIT_OFF is a list of features that are disabled by an explicit
+ +noNAME specification, in addition to the features that are transitively
+ dependent on NAME (according to REQUIRES). As with EXPLICIT_ON,
+ this is usually an empty list; comments below explain the exceptions.
+ If a feature A appears in this list then the list implicitly includes
+ any features that are transitively dependent on A (according to REQUIRES).
+
- 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
that are required. Their order is not important. An empty string means
do not detect this feature during auto detection.
- NOTE: Any changes to the AARCH64_OPT_EXTENSION macro need to be mirrored in
- config.gcc. */
