Can all > of libstdc++ and the libstdc++ testsuite be run with this flag? Yes. You may even hack opts.c to enable unit-at-a-time at -O2 and get practically useable compiler. I hope I will make unit-at-a-time by default at -O2 for 3.4 but until this happens (or in case I hit the wall somewhere) we can compile libstdc++ with it. The resulting library is few % bigger that is quite non-standard (usually I get code size reduction from c++ code in unit-at-a-time). It would be nice to understand the reason.
