CCS - C64x optimization issues

HRi

Hi,

When I'm compiling my project with -o3 everything looks fine but when I'm compiling with -pm or -pm -op3 I'm getting warnings & errors (I'm using CCS3.3 & CGT v6.1.16) -

warning: missing DW_AT_name attribute

warning: function definitions in CSU declarations are not supported

application error: cannot resolve the DW_AT_type attribute for this DIE:

[000fcb80] DW_TAG_member

DW_AT_type void

DW_AT_accessibility 0x3

application error: the type information for void was not found

What can be the reason?

Many Thanks

We would need a test case to get to the bottom of this issue. Are you able to provide a test case that reproduces the issue along with build options, so we cam investigate further?

Aarti,

I will check if I can build a small example project, is there anything I can check in the meantime,

Many Thanks,

My guess is that there is a bug related to using the -pm option in combination with -g (debug), in which case the error should go away if compiled with --symdebug:none (no debug info). I don't have much more to suggest at this time but a test case should definitely help.

Hi Aarti,

Is it possible to Email you the project without posting it on the E2E website?

Many Thanks

HR,

I will add you as a friend and start a private conversation to tell you where to email the project.

Thank you for providing the files to recreate this. I can duplicate the error and entered this as a bug in our defect tracking system. The reference # is SDSCM00037771, and you can track the status of it using the SDOWP link in my signature.

The code which emits the internal error has been reworked for release 7.0.0, and the compiler will no longer give an internal error for this test case. The changes are too extensive to back-fit to 6.1.x. A fix may yet be found for the 6.1.x branch, but it's probably not going to be soon.

You should either upgrade to 7.x or use the --no_compress option to avoid the internal error. (Of course, this will increase code size.) Not using "-pm" also seems to avoid the bug. Disabling debugging information should also avoid the bug.

Can I use release 7.0.0 with CCS3.3?

Many Thanks,

Yes, you can. Just install the codegen tools from Update Advisor download page and select that version from within CCS component manager.
