TMS570LS3137: Disable RTTI has no effect on compiled code

Brian Gestner

Part Number: TMS570LS3137

Tool/software:

Hi.

I tried to disable RTTI feature.

It does not appear it generates any different code regardless of whether the RTTI option is specified or not.

I verified this by adding options to keep the assembly file from the compilation stage and I can clearly see that with and without the RTTI option there is no difference in the assembly code generated.

Is this still the expected behavior of the most recent compiler for TMS570LS3137?

Thank you,

Brian

    Hi Brian,

    I assigned it to the compiler expert to get the help on this, hopefully he will give us an update as soon as possible.

    I presume you use the older TI Arm compiler name armcl.

    That's correct.  The issue EXT_EP-11597 was filed to have the documentation changed to reflect this behavior.  That entry refers to the C2000 compiler, but it applies to the TI Arm compiler as well.

    Thanks and regards,
