globalOffset The absolute offset of the newly linked code dataTLS The original TLS data Region from the target (can be NULL) bssTLS The original TLS bss Region from the target (can be NULL) lmap Holds information necessary to do layout

Returns the ending Offset of the Region

char * emitElfStatic::linkStatic ( Symtab *  target,
StaticLinkError &  err,
string &  errMsg 
)

NOTE: Most of these functions take a reference to a StaticLinkError and a string for error reporting purposes. These should prove useful in identifying the cause of an error Statically links relocatable files into the specified Symtab object, as specified by state in the Symtab object

target relocatable files will be linked into this Symtab

Returns a pointer to a block of data containing the results of the link The caller is responsible for delete'ing this block of data

bool emitElfStatic::resolveSymbols ( Symtab *  target,

)

Resolves undefined symbols in the specified Symtab object, usually due to the addition of new Symbols to the Symtab object. The target Symtab object must have a collection of Archives associated with it. These Archives will be searched for the defined versions of the undefined symbols in the specified Symtab objects.

target the Symtab containing the undefined symbols relocatableObjects populated by this function, this collection specifies all the Symtabs needed to ensure that the target has no undefined Symbols once the link is performed
