In my quest to port TF-M to the IAR toolchain I've run into issues with a few of the tests, and I need some hints where to look.

The cmake build command line: --- cmake .. -G"Unix Makefiles" -DPROJ_CONFIG=C:\Users\thomasto\Projects\tf-m16\trusted-firmware-m\configs\ConfigRegression.cmake -DTARGET_PLATFORM=MUSCA_A -DCOMPILER=IARARM -DCMAKE_BUILD_TYPE=RelWithDebInfo ---

This results in three similar tests that fails: ---

Executing 'TFM_SST_TEST_1018'

Description: 'Get interface with invalid thread name'   Get should not succeed with invalid thread name (Failed at C:/Users/thomasto/Projects/tf-m16/trusted-firmware-m/test/suites/sst/non_secure/psa_ps_ns_interface_testsuite.c:936)   TEST FAILED!

Executing 'TFM_SST_TEST_1019'

Description: 'Get info interface with invalid thread name'   Get info should not succeed with invalid thread name (Failed at C:/Users/thomasto/Projects/tf-m16/trusted-firmware-m/test/suites/sst/non_secure/psa_ps_ns_interface_testsuite.c:1015)   TEST FAILED!

Executing 'TFM_SST_TEST_1020'

Description: 'Remove interface with invalid thread name'   Remove should not succeed with invalid thread name (Failed at C:/Users/thomasto/Projects/tf-m16/trusted-firmware-m/test/suites/sst/non_secure/psa_ps_ns_interface_testsuite.c:1093)   TEST FAILED! ---

Where do I find the logic that determines if these tests succeed or fails?

Cheers, Thomas
