Yikes!!! Let's just say that I strongly disagree with them. 1) I do not consider -O3 to be "safe". Back a few years ago in my Redhat days, I did my first custom compiles with the Mozilla 0.95 (*NOT* Firefox 0.95) sources. The thing that drove me to learn was that the standard Mozilla 0.95 build was excruciatingly slow on a 433 mhz PIII with 128 megs of RAM. When I built with -O3, the resulting program would usually segfault on startup or soon thereafter. With -O2, Mozilla 0.95 was stable and was almost reasonably fast. 2) They miss mmx, sse, sse2, sse3, 3dnow, and mfpmath=sse, which are a lot safer than O3. -- Walter Dnes <[EMAIL PROTECTED]> My musings on technology and security at http://tech_sec.blog.ca -- gentoo-user@gentoo.org mailing list
