TMS320F28335: SYSBIOS 1405 - Compiler remark on C2000 elf builds

Part Number: TMS320F28335
Other Parts Discussed in Thread: SYSBIOS

Hello,

We are reviewing the list of defects that have been fixed in SYS/BIOS since release 6.0.76.08 - these are identified with JIRA Issue IDs in the GA Release note for subsequent versions.

Since we don't have access to the JIRA database, it would be helpful if someone could tell us more about SYSBIOS 1405 - Compiler remark on C2000 elf builds, which is mentioned in the release notes for SYS/BIOS 6.83.00.18.

Is this just a documentation issue or could it affect code generated for a C28x application running on SYS/BIOS 6.0.76.08?

Thanks,

Robert Stroud

    The remark it's referring to was an advisory from CCS--"advice: (Performance) EABI double precision is 64-bits as opposed to 32-bits for COFF. Consider changing doubles to floats for improved performance in FPU32-mode." The reason a bug was filed was that CCS was displaying it as an error rather than just advice--see the related CCS bug EXT_EP-9856

    On the SYS/BIOS side, the resolution was to just suppress the message (--diag_suppress=3195) since the use of double was deliberate.

    Thanks - that's helpful. Sounds like there's nothing to worry about here.
