Currently LLD supports --defsym only in the form of --defsym=<symbol>=<integer>, where the integer is interpreted as the absolute address of the symbol. This patch extends it to allow other symbol name to be given as an RHS value. If a RHS value is a symbol name, the LHS symbol will be defined as an alias for the RHS symbol. Internally, a LHS symbol is represented as a zero-size defined atom who has an LayoutAfter reference to an undefined atom, whose name is the RHS value. Everything else is already implemented -- Resolver will resolve the undefined symbol, and the layout pass will layout the two atoms at the same location. Looks like it's working fine. Note that GNU LD supports --defsym=<symbol>=<symbol>+<addend>. That feature is out of scope of this patch. Differential Revision: http://reviews.llvm.org/D3332 llvm-svn: 206417 |
