* Remove dead code.
STRIP_DEAD_CODE = -Wl,-static -fvtable-gc -fdata-sections -ffunction-sections -Wl,--gc-sections -Wl,-s
-Wl,-static
Link against static libraries. Required for dead-code
elimination.
-fvtable-gc
C++ virtual method table instrumented with garbage collection
information for the linker.
-fdata-sections
Keeps data in separate data sections, so they can be discarded
if unused.
-ffunction-sections
Keeps funcitons in separate data sections, so they can be
discarded if unused.
-Wl,--gc-sections
Tell the linker to garbage collect and discard unused
sections.
-s
Strip the debug information, so as to make the code as small
as possible. (I presume that you'd want to do this in a
dead-code removal build.)
* Map file.
$ ld -Map=file.map <opts> <files>
or
$ gcc -Wl,-Map=file.map <opts> <files>
