stripping symbols and dead-code



Hello!

I'm using XCode 2.2, gcc-4.0.0, ld version "cctools-590.obj~12".

0. Is there any reason to dead-strip (ld's -dead_strip) instead of
symbol-strip (ld's -s or strip)?

1. Is there any option to activate symbol-stripping besides dead-code
stripping in the build settings, besides adding -Wl,-s to "Other Linker
Flags"?

2. Why do I get an error if I use both symbol and dead-code stripping? I
pass the -Wl,-s and -Wl,-dead_strip to g++-4.0 (in "Other Linker
Flags"). The error is

/usr/bin/ld: internal error: assign_output_symbol_indexes() inconsistent
local symbol counts
collect2: ld returned 1 exit status

3. Why does code becomes bigger if I both symbol-strip and dead-strip?
Compare this:

(All numbers in bytes)
no strip
10,176,979	

dead-code strip
9,167,015

symbol strip
1,513,115

dead-code strip, then symbol strip (using strip)
1,595,959

The most efficient in my case seems to be the symbol strip. There are
about 80 kB extra if I both dead-strip and symbol-strip.

Thanks for any help!
