For those following the gcc4 stuff, the latest gcc4 snapshot (0514) just compiled the latest glibc snapshot (0421), here. Of course, they both remain both hard-masked and keyword masked for testing, as does the latest binutils, which the gcc4 snapshot needs, but they are all in my overlay and emerged successfully, glibc with the latest gcc4 and binutils, where glibc wouldn't compile with gcc4 b4. I fully rebooted after emerging glibc, everything seems to work, no unusual messages in syslog, I'm up and running KDE and xorg (also a testing snapshot, 6.8.99.5, but compiled with gcc-3.4.3-whatever, as it does /not/ seem to compile with gcc4, yet, and probably won't until at least the .6 xorg snapshot), so it looks good!
BTW, haven't done any hard number comparisons, but I do run a memory monitor sysguard applet in kicker, and if I'm not mistaken, the system with the new glibc seems to be taking ~50MB less memory, also, perhaps 75MB less. Note that the glibc ebuild forces -O2 and strips nearly all other CFLAGS. Performance doesn't feel different with the gcc4 compiled glibc, altho as I noted earlier, kde is DEFINITELY faster on the loadup since I recompiled most of the major parts of it with gcc4, probably due to the use of the new gcc4 visibility-hidden stuff used for all those intended for internal use only functions, which don't need scanned for linking now. -- Duncan - List replies preferred.
