# Some notes, Fri May 16 12:31:32 PDT 2003:
#
# Why i486 and not i386?  Because the shared C++ libraries in gcc-3.2.x will
# require 486 opcodes even when a 386 target is used (so we already weren't
# compatible with the i386 for Slackware 9.0, didn't notice, and nobody
# complained :-).  gcc-3.3 fixes this issue and allows you to build a 386
# compiler, but the fix is done in a way that produces binaries that are not
# compatible with gcc-3.2.x compiled binaries.  To retain compatibility with
# Slackware 9.0, we'll have to use i486 (or better) as the compiler target
# for gcc-3.3.
#
# It's time to say goodbye to i386 support in Slackware.  I've surveyed 386
# usage online, and the most common thing I see people say when someone asks
# about running Linux on a 386 is to "run Slackware", but then they also 
# usually go on to say "be sure to get an OLD version, like 4.0, before glibc,
# because it'll be more efficient."  Now, if that's the general advice, then
# I see no reason to continue 386 support in the latest Slackware (and indeed
# it's no longer easily possible).

# Some more notes, Mon Aug  3 19:49:51 UTC 2015:
#
# Changing to -march=i586 for 32-bit x86 as several things (Mesa being one of
# them) no longer work if constrained to -march=i486.  We're not going to use
# -march=i686 since the only additional opcode is CMOV, which is actually less
# efficient on modern CPUs running in 32-bit mode than the alternate i586
# instructions.  No need to throw i586 CPUs under the bus (yet).
