No, that's incorrect. All that --enable-target-optspace does is change the definition of CFLAGS_FOR_TARGET, which causes the GCC support libraries (i.e. libgcc, libstdc++, etc) to be built with -Os rather than -O2. It has no effect on the functionality of the compiler itself. p. _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
