copy_if_else()

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

static 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 >

static 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()

static 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.
