Ccs12

I have a few routines written in assembly. CCS9 is able to correctly link the assembly in to the C code.

Are both the projects in CCS9 and CCS12 set to use the same ABI, or is one using COFF and the other EABI?

The reason for asking is that as per Assembly Code Changes there are some different between the two ABI for creating assembler which links to C code.

I am getting errors in cCS12 that it can not find sone variables

Please provide the exact error messages.

Thanks

Most everything has been COFF up till now. I will verify. 

undefined first referenced

CalcDecel ./Include/utils.obj

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "HR17ENWV.out" not built

gmake[1]: *** [HR17ENWV.out] Error 1
gmake: *** [all] Error 2

The assembly routine is called "CalcDecel". All assembly variables are defined with an underscore "_CalcDecel".

Hi Chester, 

The new compile is indeed using eabi. I rese to COFF and then got an error about -idiv support. Changing that to "none" then popped up the error about the rts2800_fpu32_eabi.lib being incompatible. I imagine to fix that, IU have to use the "non eabi" lib file. 

However, now I would be missing out on some of the perceived new cool featured of the integer division. 

So, is there a doc detailing how to make my old assembly code "eabi" compliant?

Regards,

David

That means I don't actually need my assembly code at all.

It is possible you never did.  The type long double is 64-bit IEEE in both the older COFF ABI and the newer EABI.

I've been porting this code since its origination on an Intel 8031. Pretty sure I needed it then. When we first migrated to the 2406 on CCS2, I don't think 64bit types were available then.

Never bothered to look after that since the Assembly routine worked and never gave me problems until now...

How long has the 64 bit type been available in COFF?

Since version 6.4.x, which was first released about 8 years ago.

Thanks George, 

That makes sense. I only started using version 6 about 4 years ago. Migrated the code from 2407 (CCS3.3) to 28069 and the assembly routine worked fine. So, never even looked. But, now I know...

Now, if only I could figure out what else is going on in version 12 with the bizarre debug behavior, life would be good...
