Anyone?

[Kerash]

Anyones Input would be Credited and Most importantly, Apreciated:

I'm working on this instruction, But when it's executed it causes an FP-Stack Overflow ( Floating Point )
Can anyone see what could be causing this????

.CODE
packssdw mm7,mm0 ;Pack with Signed Saturation ( DoubleWord )
paddd mm6,mm7 ;mm6 AND mm7-- mm6 ( WrapAround )
movq [ebx],mm6 ; ( QuadWord )
sendmessage (...)
.END

Any help would be apreciated :/

I haven't done much x86 simd programming, but here is my two cents:

paddd would cause a floating point overflow (that's what a wraparound is, an overflow).

I believe you can disable the floating point overflow exception. You may want to look in to that.

You don't know much about assembly? It's Kewl, i don't know much about .. ok i should say i don't know anything about ' hardware ' tell you the truth i couldn't see the difference between a modem and a sound card, But i do know abit about software:)
and, i love assembly, 'tiss my life, Though it's not for everybody, Also why i have Windows :))

You see in the instruction ' paddd ' I us ' add ' to add the 2 ' d ' doublewords

Though, It was because i forgot the ' EMMS ' Instruction.
( That clears the MMx state by setting the floating point tag word to all 1's )
the MMx State id "aliased" on the floating point state, so all MMx instructions invalidate the floating point tag word when they execute.

and, i wanted that picture by my name but it wasn't there when i had to choose, hehe! damnit! :(

setting the floating point tag word to all 1's

Actually, I could be wrong, but I believe that disables the fp overflow exception.

BTW, if you ever have any other programming questions, feel free to ask. I'm a professional game programmer, and I believe I know quite a bit (though I could be wrong http://www.opentechsupport.net/forums/smile.gif )

Yes. That would stop the resulted stack overflow of the ' code ' supplied by myself in the original post, Though that is what i said... wasn't it? In the ... * Thinks * 3rd post i beleive?
My reply, To your reply. To be exact.

Ahh yes, i had a feeling you where somewhat ascotiated with C, or C++ or even Both,
C: Another Object-Oriented Language i'm thinking, Suposedly a ' high-level ' language, I don't know. HLA looked to me as if it was modeled after C, Thus the reasson i stayed away from it.

Though congrats on your Bioware Status.
A carreer in Optimizing sounds apealing:)
What size of a team are you used to working with?
And what area's do you have a foot in at Bioware?

What does team include in your definition?

If it's just programmers, then the smallest I've worked with is two others, and the largest is 10 others.

If it includes artists, designers, writers, etc, the smallest I've worked with is probably 6, and the largest is probably somewhere in the mid 20s.

The only ' Scripting ' You could say, That i do would be what i do with Javascript, I guess you could say.

Though i am a Software Guru, and an Assembly Hag, I don't like Posers and i don't like Spammers, i also disslike 90% of the people on battle.lag, I'm 16, and i'ma pot head that like to get all fried and discuss Software, And tech support for people that need help, As well as i do what i want and Stick up my Two Middle fingures when someones got a problem with it. Cause i just don't give a fawk.

Alot of Folks *** with me.. It's hard to hang out in Crowds.....but i guess thats the price you pay, To be such a big shot like i am.......People don't know, about things i say or do, They don't understand... about the Sh!t that i've been thru, People Claiming they know me, When they don't know the half of it.

[Canis Lupus]

Hmmm, since this thread has obviously gone south, I will therefore close it.

Sorry Wargy, but I try to avoid deleting threads ... as for Kerash, and anyone else who wants to discuss matters pertaining to TG, please do so at "their" forums, or take it out on the Rants & Raves Forum - that's why that forum is there (but I would recommend that you use the TG forums if you want to criticize anything pertaining to TG).

Boy, this thread went bad real fast. Hope everyone respects my decision to close it. And please try to settle things in the right turf.

Thread closed...
