I've read that gcc 4 is supposed to have this fantastic new optimization scheme, but after getting a minimally working lfs, it is definitely much slower than my gcc 3.4.3 generated lfs. But I changed optimization flags a bit, so I'm wondering if anyone has any advice on the following:
I have a dell inspiron laptop, running a pentium m 730 (1.6 GHz pentium m dothan core). On my first lfs build I used gcc 3.4.3 with -O3 -march=i686 On my second lfs build I used gcc 4.0.1 with -O2 -march=pentium-m It seemed slower in many things such as emacs (started in less than a second on the first build, about 2 seconds on second build). Unfortunately, there were more than one thing changed. So I don't really want to build the 8 possible choices to see which one works the best. Does anyone have any special insight to give? The optimization hints and writings all seem to only pertain to gcc 3.4 or before. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
