Compiler/TMS320F28377S: No update of DP register

Do I miss something, or is this a compiler problem?

Unfortunately, it appears to be a compiler problem.  To address this problem, we need a test case that allows us to reproduce it.  We don't need the whole program.  Just the one source file with these problem assignment statements.  Please submit it as described in How to Submit a Compiler Test Case.

Thanks and regards,

Hi George.

I've attached the requested pp file.

ts_src01.pp.txt

I've found the problem in "FRAM_Fill" function.

Compilerversion is v17.9.0.STS.

Here is the compilercall:

If you need something else, let me know.

Thank you for submitting a test case.  I can reproduce the problem.  I filed CODEGEN-3795 in the SDOWP system to have this addressed.  You are welcome to follow it with the SDOWP link below in my signature.

Thanks and regards,

Hi George.

Thanks for the Information.

Do you know how to workaround this problem? And do you know under which conditions this problem will occur? How can I find possible locations in my source code where the problem may exist?

Thank you
