copy_if_else()

template<class InputIt, class OutputIt1, class OutputIt2, class UnaryPredicate>

std::pair< OutputIt1, OutputIt2 > copy_if_else ( InputIt First, InputIt Last, OutputIt1 d1, OutputIt2 d2, UnaryPredicate Predicate )

static

Copy elements in the range [First, Last) to d1 when the predicate is true or d2 when the predicate is false.

This is essentially both std::copy_if and std::remove_copy_if combined into a single pass.

find_best()

template<class InputIt, class UnaryPredicate, class Comparator>

InputIt find_best ( InputIt First, InputIt Last, UnaryPredicate Predicate, Comparator BetterThan )

static

Find the best match in the range [First, Last).

An element matches when Predicate(X) returns FindBest_Match or FindBest_PerfectMatch. A value of FindBest_PerfectMatch also terminates the search. BetterThan(A, B) is a comparator that returns true when A is a better match than B. The return value is the position of the best match.

This is similar to std::find_if but finds the best of multiple possible matches.

getMatchingLoType()

unsigned getMatchingLoType ( const ELFRelocationEntry & Reloc )

static

Determine the low relocation that matches the given relocation.

If the relocation does not need a low relocation then the return value is ELF::R_MIPS_NONE.

The relocations that need a matching low part are R_(MIPS|MICROMIPS|MIPS16)_HI16 for all symbols and R_(MIPS|MICROMIPS|MIPS16)_GOT16 for local symbols only.
