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.
