Member Function Documentation

get_machine()

virtual uint16_t Halide::Internal::Elf::Linker::get_machine ( )

pure virtual

get_flags()

virtual uint32_t Halide::Internal::Elf::Linker::get_flags ( )

pure virtual

get_version()

virtual uint32_t Halide::Internal::Elf::Linker::get_version ( )

pure virtual

append_dynamic()

virtual void Halide::Internal::Elf::Linker::append_dynamic ( Section & dynamic )

pure virtual

get_got_entry()

virtual uint64_t Halide::Internal::Elf::Linker::get_got_entry ( Section & got, const Symbol & sym )

pure virtual

Add or get an entry to the global offset table (GOT) with a relocation pointing to sym.

needs_plt_entry()

virtual bool Halide::Internal::Elf::Linker::needs_plt_entry ( const Relocation & reloc )

pure virtual

Check to see if this relocation should go through the PLT.

add_plt_entry()

virtual Symbol Halide::Internal::Elf::Linker::add_plt_entry ( const Symbol & sym, Section & plt, Section & got, const Symbol & got_sym )

pure virtual

Add a PLT entry for a symbol sym defined externally.

Returns a symbol representing the PLT entry.

relocate()

virtual Relocation Halide::Internal::Elf::Linker::relocate ( uint64_t fixup_offset, char * fixup_addr, uint64_t type, const Symbol * sym, uint64_t sym_offset, int64_t addend, Section & got )

pure virtual

Perform a relocation.

This function may opt to not apply the relocation, and return a new relocation to be performed at runtime. This requires that the section to apply the relocation to is writable at runtime.
