Peter Collingbourne fdb1a6c341 DataFlowSanitizer: greylist is now ABI list. ... This replaces the old incomplete greylist functionality with an ABI list, which can provide more detailed information about the ABI and semantics of specific functions. The pass treats every function in the "uninstrumented" category in the ABI list file as conforming to the "native" (i.e. unsanitized) ABI. Unless the ABI list contains additional categories for those functions, a call to one of those functions will produce a warning message, as the labelling behaviour of the function is unknown. The other supported categories are "functional", "discard" and "custom". - "discard" -- This function does not write to (user-accessible) memory, and its return value is unlabelled. - "functional" -- This function does not write to (user-accessible) memory, and the label of its return value is the union of the label of its arguments. - "custom" -- Instead of calling the function, a custom wrapper __dfsw_F is called, where F is the name of the function. This function may wrap the original function or provide its own implementation.
