            Bug ID: 34948
           Summary: -defsym should accept expressions, not just symbols
           Product: lld
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org

The -defsym SYM=VAL option in other linkers accepts an absolute address         
constant (e.g. 0 or 0x1234) or even an expression like 1+2 or symbol+3for       
VAL, not just a symbol name.  In gold and BFD, it takes basically any           
expression you can use in freestanding linker script contexts like
