linear assembly - copy routine not working for C6713

Robert,

Why are you writing in assembly instead of C? The C compiler is pretty good.

Which versions of tools are you using? CCSv?, CodeGen ?, emulator (board?) or simulator (which?)

How do you go about debugging something like this? Since this must be an exercise to learn to write in assembly, you will not gain anything by someone telling you what's wrong, even if we could do that.

Have you tried passing smaller arguments, like size=8 and the inc values being reasonably small like 2, 3, 4, etc? Does it work right in those cases?

When you are debugging, you have to find out exact numbers, not "about 380". Run it for 379 and look at memory, then run it for 380 and look at memory, then 381, or wherever you need to be to know the boundary between working and failing.

What you learn from those starting tests will lead you to the next set of tests, and somewhere along the way you may notice odd behavior in memory or in the registers as you single-step through the assembly code.

You can look into more advanced breakpoints than just "stop here". You can associate counters with breakpoints and make different things happen when you reach a breakpoint other than just Halt.

Please post back with what you try, what results you get, and what new insights you have that can lead to some additional steps.

Your function name implies copying integers (i2i) and your text says you are copying integers, but your function is copying shorts. The C function memcpy copies bytes.

Regards,
RandyP

Randy,

CCSV5.1, 7.3 compiler tools, 5.41.11.38 BIOS, 6713DSK. 

I debug by stepping over the function and dumping the source and destination, and comparing the two offline.  It’s consistently good until 372 (out of 1024 requested).

I am passing in shorts (Int16), so ldh, sth is correct.  

This code was ported from CCSV3.3, where it (and other) linear assembly was working fine. 

Regards,

Robert

Robert,

With the added history of your code, my statement above about "an exercise" sounds patronizing and rude. Sorry.

Can you please post the assembly output for just this function from the CCS 3.3 version and the assembly output for this new version? The -k compiler switch will tell the compiler to keep a copy of the .asm file in your output folder, usually .\Debug or .\Release.

Regards,
RandyP

Randy,

I'm not able to compile under CCS 3.3 anymore, but attached is the latest, 5.1 version.

Thanks,

Robert

Find a way to get the assembly code for the version you said worked. There is no reason I can see for this to not work. Try loading the old one and looking in the Disassembly window.

You will also need to go back to my first post and report back on your results using the debug techniques I mentioned.
