It is the time to build the gcc package itself, AFAIU. I was also initially confused.

Do bear in mind in these numbers that we're currently building on PandaBoards, TrimSlices, and the like. They have nothing like the many MB of L2 cache you're going to see in real 32-bit ARM servers in the coming months, which will also have much improved on-chip IO. I actually think the 2-2.5x speedup estimates we've been given will end up being low because for IO bound operation we're going to have up to 4x the cache, 4x the RAM, and a lot of other microarchitectural improvements.

With the ARM instruction set, unless using Thumb, you have each instruction coded on 32 bits, so 256 assembly instructions weight 1 Kbyte.

This is not generally true. Just compare the installed sizes across architectures for e.g. http://packages.debian.org/wheezy/libc6 or http://packages.debian.org/wheezy/coreutils
2 hour ARM build Posted Mar 25, 2012 0:25 UTC (Sun) by jzbiciak (✭ supporter ✭, #5246) [Link] I wonder what the compile time might look like on this beast when it comes out. (Full disclosure: I work on the team making that chip, so mine is more than just a passing interest.)

Give a few samples to us Debian folks for use in build machines, and we'll let you know! :-)
Seriously, we're always looking for donations of newer/faster hardware for building and testing with.
