[FX] elfurbe: Nightly [Branch|Trunk/OSX] (G3/G4/G5/Intel)

[elfurbe]

Hm. That's probably what I'd do. Sometimes these nightlies can wreak havoc in the profile folder.

what optimizations do these builds have?

[elfurbe]

I compile all with -O3, and I use altivec and auto-vectorization where applicable, and that's it. I played with lots of other options when I started, but I've found those to be good enough.

Had some trouble building for 08.02, seems to be rectified today.

How do you know which to use 7400 or 7450? I just acquired a TiBook 550MHz, I think that it has a 7440 chip (not sure).

[elfurbe]

You'll have a 7400 compatible.

or, if you're really into understanding it:

I won't pretend to understand the nature of the whole thing, but 7450, 7455, 7457, 7447/a are the ones that get benefit from the "7450" gcc option and 7410 and 7440 gain with the "7400" option. Your Ti 550 does have a 7440, so you'll want the 7400 version.

Methinks.

All 744x CPUs are members of the 7450 architecture. 744x is the same as 745x without the provision for level 3 cache. 7440 users will benefit more when code is tuned for 7450.

This post used to be a duplicate of the one above it, but now it's just a useless piece of nothing.

LOL!

Thanks. 7450 optimization it is then...

Offtopic: Man, there is such a big difference going from a PMG5 dual 2GHz to a TiBookG4 550MHz. But I can't complain since it is a free hand-me-down. I only have to pay to upgrade the RAM from 256MB to 768MB!

Ontopic: elfurbe, you might want to put up a FAQ about which of your builds on which machines...

[elfurbe]

I bow to your authority, mento.

As to the FAQ, that's not a bad plan. Maybe I'll add a bit to the webpage explaining which builds go with which machines.

The first triumph of my totally automated build system! Getting the cron to work was a pain, but last night it kicked up the jams. Viva el cron!

So, hopefully, you (that's an all-inclusive you representing anyone who would want to download my builds) can expect regular nightly updates, rather than the sporadically timed builds I've been performing.

[elfurbe]

Added an FAQ and my mozconfig to my top post. Hopefully it answers the questions properly.
