## ◆ 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.
