Detailed Description

Target - Wrapper for Target specific information.

For registration purposes, this is a POD type so that targets can be registered without the use of static constructors.

Targets should implement a single global instance of this class (which will be zero initialized), and pass that instance to the TargetRegistry as part of their initialization.

createMCSymbolizer - Create a target specific MCSymbolizer.

Parameters

TT	The target triple.
GetOpInfo	The function to get the symbolic information for operands.
SymbolLookUp	The function to lookup a symbol name.
DisInfo	The pointer to the block of symbolic information for above call back.
Ctx	The target context.
RelInfo	The relocation information for this target. Takes ownership.

inline

createTargetMachine - Create a target specific machine implementation for the specified Triple.

Parameters

TT	This argument is used to determine the target machine feature set; it should always be provided. Generally this should be either the target triple from the module, or the target triple of the host if that does not exist.

isValidFeatureListFormat()

bool Target::isValidFeatureListFormat ( StringRef FeaturesString )

static

isValidFeatureListFormat - check that FeatureString has the format: "+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. The string must match exactly that format otherwise MCSubtargetInfo::ApplyFeatureFlag will fail. For example feature string "+a,+m,c" is accepted, and results in feature list {"+a", "+m", "c"}. Later in ApplyFeatureFlag, it asserts that all features must start with '+' or '-' and assert is failed.
