Deadstripping

asmjockey — Sat, 05 Dec 2009 03:59:36 GMT

Hello,

I've not found a way to turn off deadstripping within the IDE. Is there a way to do this without linking at the command line?

Thanks!

From Target Setting Panels -> ColdFire Linker -> Select "Disable Deadstripping"

Sorry, being explicit might be helpful, huh? I'm using the HCS12 (ver 5) and the 56800E.

Thanks!

Hi,

for CW for HCS12: you can add the objects that you don't want to optimize into the ENTRIES section of your .prm file.

You can also try this: ( I used it on my 52259 project)

#pragma force_active on

// put the code you wish to keep ( not optimized away) here

#pragma force_active off

Thank you both, eGuy and stanish!

I'm really looking for a global handling - running an RTOS that indirectly uses lots of unlabeled pointers. Manually linking with a postpended '+' on each obj works fine, and I was hoping there's a way I didn't see to do that. I guess maybe a linker.bat to add the '+' might have to be it.

I appreciate it!

Hello

Notation to use is different for DSP56800E and for HC12.

For HC12 if you want to disable dead striping for a module called myfile.c, use following notation in your application .prm file.

ENTRIES
myfile.c.o:*
END

You can enumerate several files in the ENTRIES block. Just use space character as separator.

For DSP58000E, you can disable dead striping for a specific section using linker command KEEP_SECTION.

You just have to place whole code from that module in a user defined section and disable dead striping for that section.
