template <class Module, typename TlsDescResolver>

struct ResolverDefinition

Defined at line 158 of file ../../src/lib/elfldltl/include/lib/elfldltl/resolve.h

This type implements a Definition which can be used as the return type for

the `resolve` parameter for RelocateSymbolic. See link.h for more details.

The Module type must have the following methods:

* const SymbolInfo

symbol_info() const

Returns the SymbolInfo type associated with this module.

This is used to reify the Sym in the referring module to a name.

* size_type load_bias() const

Returns the load bias for symbol addresses in this module.

* size_type tls_module_id() const

Returns the TLS module ID number for this module.

This will be zero for a module with no PT_TLS segment.

It's always one in the main executable if has a PT_TLS segment,

but may be one in a different module if the main executable has none.

* bool uses_static_tls() const

This module may have TLS relocations for IE or LE model accesses.

* size_type static_tls_bias() const

Returns the static TLS layout bias for the defining module.

* fit::result

<bool

, TlsDescGot> tls_desc(Diagnostics

, const Sym

, Addend addend) const

* fit::result

<bool

, TlsDescGot> tls_desc(Diagnostics

) const

See elfldltl::RelocateSymbolic API comments about the two overloads.

This implements that method but for some particular defined symbol in

`.symbols_info().symtab()`.

* fit::result

<bool

, const Sym*> Lookup(Diagnostics

, SymbolName

name) const

This can usually be just `return fit::ok(name.Lookup(symbol_info()));`.

It's responsible for looking up a symbol name in the module.

It can return failure to declare that resolution has failed entirely.

It returns success with nullptr just to indicate this module does not

define this symbol name. The returned pointer must be from symbol_info()

so that its string table can be used.
