3) sending women you don't like pictures of dog tits over twitter"

Atari �it�s 1994 and we literally have no money� Corporation

the GPU and DSP each have internal 32-bit SRAM that you can copy programs to. that�s not affected by this. the external memory bus is 16-bit and a lot slower anyway.

a few years ago someone figured out that you can reliably do jumps in external memory as long as the alignment for everything is just right but the speed penalty makes it no good

someone needs to fix this in an emulator�

�and see what it breaks

i found the article with the deets on how to make it work actually

JUMP from locations must be LONG aligned (Addresses ending in 0,4,8 or C in hexadecimal)� sometimes for jumps between Local and Main, PHRASE alignment seems necessary (Addresses ending in 0 or 8 in hexadecimal - actually recent studies have shown some cases where the JUMP FROM address in local has needed to be word aligned - the jump too was always LONG)) [Actually there's even a further point - if the jump is called very frequently - sometimes even the alignment and MOVEI seem not to help - one therefore needs to try to keep the jumps a little further apart in time]
In order to help clear the pipeline/pre-fetch for jumps between Main Ram and local RAM on the RISC chip, it is advisable to immediately precede the JUMP with a MOVEI. (Recent work has indicated that it is sometimes beneficial if the MOVEI is NOT the regester used in teh JUMP)
JR from locations seem to be free
External page jumps must be LONG aligned
Internal page jumps must be word offset from long aligned (addresses ending in 2,6,A or E in hexadecimal)
Two NOP's should come after a JUMP or a JR instruction (experimentation with a single operand instruction instead of the first NOP is possible).

anyway I wrote this as part of the line blitting routine to take advantage of the delay slot and thus save 1 (one) cycle and now I feel dirty

code:

	;; 1-phrase pitch, 8-bit pixels, 320px width, XADD = ?
	cmpq	#0,SLOPE		;is slope 0?
	jr	eq,.slope_is_zero	;yes, add one to X per pixel instead of the slope register

	;; slope is not zero
	movei	#PITCH1|PIXEL8|WID320|XADDINC,TEMP1 ;X += X step registers
	jr	t,.step_sign_check		    ;continue setting blitter registers
	store	TEMP1,(B_A1_FLAGS)		    ;always executed after the jump. CYCLE SAVED

.slope_is_zero:
	movei	#PITCH1|PIXEL8|WID320|XADDPIX,TEMP1 ;executed if slope == 0
	store	TEMP1,(B_A1_FLAGS)

.step_sign_check:
[set more registers...]

one cool thing about the RISC chips: their divide units support both integer divides and fixed-point divides so 3D math is easier without an FPU

code:

	;Slope calculation.
.calculate_slope:
	;TODO: division by 0 returns 0xFFFFFFFF per hardware manual
	move	Y_DIST,DIVIDEND
	move	X_DIST,DIVISOR
	
	;Set up for 16.16 divide
	moveq	#1,TEMP1
	movei	#G_DIVCTRL,TEMP2
	store	TEMP1,(TEMP2)
	
	div	DIVISOR,DIVIDEND	;destination / source
	move	DIVIDEND,SLOPE		;slope = DIVISOR/DIVIDEND
	
	;; back to integer divide
	moveq	#0,TEMP1
	movei	#G_DIVCTRL,TEMP2
	store	TEMP1,(TEMP2)

Yeah, I saw the changed Twitter handle, then clicked through and saw her profile changed too, so I figured I had at least a 50% chance of being right.

That's generally the amount of confidence I have in my programs being right, too.

unless they changed it back again, subscription also gets you permanent fallback for whatever comes out a year before the license expires (so if you get a 1 year license, it's the current version, if you get a 2 year license it's whatever comes out in the next year)

jetbrains had a problem: they had to hold features because they needed to make upgrades worthwhile, and they would rather release features when ready and adopt an evergreen model. they wanted to move to a straight subscription model, but customers who liked having real ownership of the yearly release were mad, so they made it so you could get ownership of a release if you paid for a year. everybody is super happy about it and got what they wanted
