     3 * Remove dead code.

     5   STRIP_DEAD_CODE = -Wl,-static -fvtable-gc -fdata-sections -ffunction-sections -Wl,--gc-sections -Wl,-s

     6 

     7   -Wl,-static

     8                 Link against static libraries. Required for dead-code

     9                 elimination.

    10 

    11   -fvtable-gc

    12                 C++ virtual method table instrumented with garbage collection

    13                 information for the linker.

    14 

    15   -fdata-sections

    16                 Keeps data in separate data sections, so they can be discarded

    17                 if unused.

    18 

    19   -ffunction-sections

    20                 Keeps funcitons in separate data sections, so they can be

    21                 discarded if unused.

    22 

    23   -Wl,--gc-sections

    24                 Tell the linker to garbage collect and discard unused

    25                 sections.

    26 

    27   -s

    28                 Strip the debug information, so as to make the code as small

    29                 as possible. (I presume that you'd want to do this in a

    30                 dead-code removal build.)
