Function Documentation

static bool computeCtorDtorAddress	(	relocationEntry &	rel,
		Offset	globalOffset,
		LinkMap &	lmap,
		string &	errMsg,
		Offset &	symbolOffset
	)			`[static]`

Given a relocation, determines if the relocation corresponds to a .ctors or .dtors table that requires special consideration. Modifies the passed symbol offset to point to the right table, if applicable.

rel The relocation entry to examine globalOffset The offset of the linked code (used for symbol offset calculation) lmap Holds information about .ctors/.dtors tables errMsg Set on error symbolOffset Modified by this routine to contain the offset of the table

Returns true, if there are no errors including the case where the relocation entry doesn't reference the .ctors/.dtors tables.
