Compiler/AM5726: Address Sanitizer Not Included in the SDK

mustafa.gonul

Part Number: AM5726

Tool/software: TI C/C++ Compiler

Hi,

I am currently working on BB-X15 with SDK 6.03. I have a project and I would like to use address sanitizer on this project. When I enable address sanitizer flags, at the linking stage, I get an error regarding libsasan_preinit.o. When I check the SDK installation, I have seen that there is no libasan_preinit.o in the /usr/lib which is the default directory for the file. When I investigate deeper, I have seen that libsanitizer.spec is also missing. When I check GCC 8.3, I have seen these files are included.

I appreciate if you can include address sanitizer in the SDK for the next releases.

Kind regards,

Mustafa

Hi Mustafa,

I need to some further study on this and see if this can be supported and what is the dependency with the SDK.

To give a helping hand, can you please elaborate what you are trying to do and why/how you think this should be implemented in the SDK? Any pointers would be useful.

Regards

Karthik

Hi Karthik,

Address sanitizer is a GCC feature to be used to detect memory leaks. For an application, it can be enabled/used with several flags: -fsanitize=address for compiler, -fsanitize=address -lasan for linker. For further information you can check the following links:

There are several parts of the address sanitizer included in the SDK, header files, libraries, spec files, object files etc. Other parts except two files mentioned above as far as I see are in the SDK, it means that you have enabled the address sanitizer for the GCC but not copied these two.

In SDK 5, we were using this feature without no problem (I have rechecked the SDK5 installation, these files are there.)

But in SDK 6 these files are missing and unfortunately we cannot use address sanitizer because of that:

In SDK5, address sanitizer : Working
In SDK6, address sanitizer : Not working

Kind regards,

Mustafa

Hi Mustafa,

I have been trying to check this in the background and there is a requirement logged to check this on the next release.

Would you please let me know if you have a workaround/solution for now and that this can be addressed in the future?

Regards

Karthik

Hi Karthik,

Sorry for late response. Unfortunately, we have no workaround/solution on our side. Address sanitizer is one of the most used feature of GCC at our side, I am very glad that it will be in the next release.

Kind regards,

Mustafa
