Hi Ken,

There should be no difference from GNUARM or ARMCLANG in this respect. Should not need any special switches.

If you wish to try out our tools, you can download a trial version until we have arranged for a permanent solution, see: https://www.iar.com/iar-embedded-workbench/#%21?architecture=Arm

Cheers, Thomas

Hi Thomas,

I have a question about IAR compiler since we verify default GNUARM and ARMCLANG in the existing sources. If we are trying to implementing some internal version of libc APIs like 'memcmp', would IAR link with this implemented version first, or it just report a link error of duplicated symbol? Any switches do we need to assign to support this?

Thanks.
