Rose::BinaryAnalysis::Partitioner2::FunctionPaddingMatcher Class Referenceabstract

Description

Base class for matching function padding.

Function padding is bytes that appear immediately prior to the entry address of a function usually in order to align the function on a suitable boundary. Some assemblers emit zero bytes, others emit no-op instructions, and still others emit combinations of no-ops and zeros. It's conceivable that some compiler might even emit random garbage.

Attempt to match padding.

Attempts to match function padding that ends at the address immediately prior to anchor. If a match is successful then the return value is the starting address for the padding and must be less than anchor. When no match is found then anchor is returned. The size of the matched padding is always anchor-retval where retval is the returned value.

Implemented in Rose::BinaryAnalysis::Partitioner2::ModulesM68k::MatchFunctionPadding.
