Oh man
05:47
<&McMartin>
Despite having way more registers and useful addressing modes, I think the 386 just showed the M68000 what for
05:48
<&McMartin>
64-bit integer math is soooooooo much easier on the 386
06:32
<&Reiver>
...what.
06:33
<&McMartin>
Despite being a 32-bit chip, it's got special instructions that let you do 64-bit multiplies, divides, and bit-shifts without touching memory
06:33
<&McMartin>
Generally by reading or writing multiple registers at once
06:34
<&McMartin>
You have to do a lot more juggling with the other (generally acknowledged as better) chip because it loses data along the way, at least in its earliest incarnations
06:34 * McMartin is trying to backport some nice routines into DOS-era systems but they're kind of full of 64-bit math, you see~

Ha HA

Victory

<&McMartin>
My hand-written version of this code hits RAM "unnecessarily" half as often and is 15% smaller compared to gcc -m32 -O2.
07:11
<&McMartin>
Of course, without -m32 the "necessary" memory hits drop to 0 for all concerned >_>
07:11
<&McMartin>
Also looking at its generated code let me rewrite some bits more efficiently
07:12
<&McMartin>
... but that "more efficiently" turned out to be "save one byte"

< simon_>
what word class is 'sent' in 'a sent letter'? that's not an adjective, is it? is it an adverb?
11:09
<~Vorntastic>
participle
11:40
<~Vorntastic>
Which is to say: it's an adjective formed from a verb via the participle form(s)
11:41
<@TheWatcher>
Which is to say: grammar causes headaches.
11:42
<@TheWatcher>
(But it's the best we've got. Thanks English. Thenglish.)
