Re: New shared libraries of zlib and pnglib available

Hi Thorsten, no LDG in VISION are only used for dynamic modules such as rotation, gamma correction, blackhole, etc. Filters could be implemented in LDG but it was done like this simply because of the more comlicated user interface it requires (matrix values to enter). A LDV (=VISION's LDG) could pot...

Re: New shared libraries of zlib and pnglib available

Hi Thorsten, Wow, that's a nice catch :-)! WHo is maintening LDG now? Olivier/Mikro? It would be nice to have official new release with this fix. There is currently a workaround in VISION but better have a clean release. The workaround you suggest is not viable in VISION as by its nature all LDG and...

Re: All FreeMiNT builds again available and more!

Hi mikro, nice initiative :-) I had to rename mint\1-19-cur\xaaes.km to mint\1-19-cur\xaaes040.km to boot properly on Aranym. However, this is not the end of the story: I don't have my host drive(H:) anymore, I'm did not dig into this but AFAIK, only Aranym configuration matters here no? Also my net...

Re: SHA256 for all Ataris

Hi,

just updated https://github.com/JeanMars/SHA256 with GCC support and makefile for 68000/68000/ColdFire(untested)
Results are pretty weird to me; gcc does it better even against human assembly code, purec looks far away which is surprising.

Cheers,
Jean

Re: Using gcc, basic questions

Looks like I found response for #2: http://tho-otto.de/crossmint.php m68k-atari-mint-gcc is the C compiler. m68k-atari-mint-g++ is the C++ compiler. They just work. I only tested the C and C++ languages, but other languages may work, too. If you want to generate DRI symbols in the final executable, ...

Using gcc, basic questions

Hi, just starting using gcc, I have a couple of basics questions: - I installed gcc 7.3.0 for native atari under Aranym, latest gcc is 8.2.3 for cross compiler, any chance 8.2.3 is available for native? - I installed gcc-7.3.0-m68020-60mint.tar.bz2 as running in Aranym on a 68060, looks like generat...

Re: SHA256 for all Ataris

Hi, thanks for links. Yes I'm aware that gcc binaries are much larger than PureC ones because of posix, just wanting to give gcc a try for some tests or additional tool dev. To me, main lack is not being able to use a debugger with gcc. PureD is so nice for that. Wil first go for native compilation ...

Hi, That will be tough. The implementation i used already has everything "unrolled", and does not use a table like your assembler version. . I don't get your point here. Do you refer to .constants label in assembly file? To me it should be faster accessing these by an address register (a5)...

Re: SHA256 for all Ataris

Hi, Thorsten, you ruined my day ;-) wow I'm very impressed by how much efficient is code generated by gcc; honestly I did not expect a 'C' code to be faster than 68k one in this context. Typically I expected a about a 1/2 ratio, like code generated by PureC. I don't think 68020 instructions would he...

Re: SHA256 for all Ataris

No, I did not take time to investigate this; just considering the way assembly code looks to make optimum usage of registers and code compacity, I would expect some pretty nice speed benefit compared to 'C' codes I've seen (openssl, polarSSL). If someone has some benchmark with these, that would be ...

SHA256 for all Ataris

Hi all, When debuging VISION, I needed to compute some basic hash to know if a given buffer has been changed; I made something pretty simple but by curiosity I looked if there is a SHA256 implementation on Ataris. The ones I've seen, like polarSSL, looked too much 'C' oriented for me, I expected som...

Hi, If you want test for appl_getinfo you can use this: https://freemint.github.io/tos.hyp/en/a ... l_xgetinfo Problem with this routine is that it won't return support for a classic Falcon as AES is 3.30.

Re: VISION 4.5a is out!

Hi Eero, appl_getinfo is only available on TOS > 4.00; for regular Falcon (I mean running original TOS) version is 3.30. So there is a special case on this because VISION knows it features popups. What I can do is to test against this version (3.30) for Falcon to not use AES popups in your case. For...

Re: VISION 4.1a is out!

Hi Cyprian,

I made the test; set a 256 colors resolution, loaded a JPG image into VISION, saved it to IMG.
VISION/Smurf/Pixart loads it OK but Thing loads it wrongly,
So not sure it's a VISION issue here.
