Static Public Member Functions
static bool hasFlag (StringRef Feature)
Determine if a feature has a flag; '+' or '-'.
static StringRef StripFlag (StringRef Feature)
Return string stripped of flag.
static bool isEnabled (StringRef Feature)
Return true if enable flag; '+'.
static LLVM_ABI void Split (std::vector< std::string > &V, StringRef S)
Splits a string of comma separated items in to a vector of strings.

Manages the enabling and disabling of subtarget specific features.

Features are encoded as a string of the form "+attr1,+attr2,-attr3,...,+attrN" A comma separates each feature from the next (all lowercase.) Each of the remaining features is prefixed with + or - indicating whether that feature should be enabled or disabled contrary to the cpu specification.
