debian architecture history question

From: Paul E Condon on 11 Jun 2010 12:50 I'm in the process of working a bug on my desktop PC. The CPU is a Semperon (32bit AMD). I recall that I once used i686. But now I think I am using i386. When I make a bug report, reportbug includes the line: "Architecture: i386 (i686)" I guess that i686 has somehow been merged into i386, but I cannot confirm this guess by googling. I only get old discussion, nothing announcing a resolution to the discussion. I'm sure there is an announcement somewhere that explains how the issue was resolved and why everyone should be happy. I'd like to read it and be happy. But I can't find it. Please help. -- Paul E Condon pecondon(a)mesanetworks.net -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

The kernel may be built for a 686-compatible processor, though. > When I make a bug report, reportbug includes the line: > "Architecture: i386 (i686)" > > I guess that i686 has somehow been merged into i386, but I cannot > confirm this guess by googling. This is wrong. The first string is the output from "dpkg --print-architecture", the one in parentheses comes from "uname -m".

Other than the kernel, which is compiled for 686 instruction sets, and maybe a few core packages that would benefit from targeting the 686 architecture, Debian compiles the rest of the packages against 386. -- .

The i486, i586, and i686 instruction sets were strict supersets of the i386 instruction set. Mostly likely this line is reporting your dpkg architecture and your kernel architecture. The dpkg architecture is still called i386, but I believe the libc requires the i486 instruction set, and there is no pre-compiled kernel image that does not require at least the i486 instruction set. I think all the 32-bit processors on the market right now are i686 or better, but there might be some i586 embedded processors on the market still. Debian provides a pre-compiled kernel images that depends on the i686 architecture, and can therefore take advantage of the extra (faster) instructions in i686 processors. I'm not exactly sure what the policy is for packages in the i386 archives in general, but I believe they are supposed to have -586 or -686 in their package name is they require those instruction sets. Some of the A/V codec libraries had stuff like that for a while, IIRC. I believe currently they auto-probe for the processor features and use what is available at runtime. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss(a)iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
