Hi, I've been looking into generating code coverage reports from RTEMS tests in RTEMS 6. I'm using SPARC with gr712rc BSP.
I'm following the steps outlined in the coverage analysis documentation https://docs.rtems.org/branches/master/user/testing/coverage.html However, when I run it on any tests, even sample/hello.exe I get the logs in lines of the following: `RTEMS Testing - Tester, 6.0.not_released Command Line: ./rtems-test --rtems-tools=/home/yoman/RTEMS/rtems/6 --log=log_leon3_sis --rtems-bsp=leon3-sis-cov --coverage /home/yoman/RTEMS/src/rtems/build/sparc/gr712rc/testsuites/validation/ts-validation-0.exe Host: Linux ubuntu 5.13.0-35-generic #40~20.04.1-Ubuntu SMP Mon Mar 7 09:18:32 UTC 2022 x86_64 Python: 3.8.10 (default, Nov 26 2021, 20:14:08) [GCC 9.3.0] Host: Linux-5.13.0-35-generic-x86_64-with-glibc2.29 (Linux ubuntu 5.13.0-35-generic #40~20.04.1-Ubuntu SMP Mon Mar 7 09:18:32 UTC 2022 x86_64 x86_64) [1/1] p:0 f:0 u:0 e:0 I:0 B:0 t:0 L:0 i:0 W:0 | sparc/leon3-sis: ts-validation-0.exe Passed: 1 Failed: 0 User Input: 0 Expected Fail: 0 Indeterminate: 0 Benchmark: 0 Timeout: 0 Test too long: 0 Invalid: 0 Wrong Version: 0 Wrong Build: 0 Wrong Tools: 0 Wrong Header: 0 ---------------- Total: 1 Average test time: 0:00:02.008333 Testing time : 0:00:02.008333 Running coverage analysis (/home/yoman/RTEMS/rtems/6/bin/leon3-sis-coverage) Function is both external and inlined: _Message_queue_Create Function is both external and inlined: _Message_queue_Create Function is both external and inlined: _Message_queue_Create Function is both external and inlined: _Thread_Initialize_information Function is both external and inlined: _Thread_Initialize_information Function is both external and inlined: _Thread_queue_Initialize Function is both external and inlined: _Thread_queue_Initialize Function is both external and inlined: _Thread_queue_Resume Function is both external and inlined: _Thread_queue_FIFO_first Function is both external and inlined: _Thread_queue_FIFO_first Function is both external and inlined: _Thread_CPU_budget_consume_and_yield Function is both external and inlined: _Thread_CPU_budget_consume_and_yield Function is both external and inlined: _Thread_Join Function is both external and inlined: _Thread_Join Function is both external and inlined: _Thread_Set_state_locked Function is both external and inlined: _Thread_Set_state_locked Function is both external and inlined: _Thread_Set_state_locked Function is both external and inlined: _Thread_Set_state_locked Function is both external and inlined: _Timecounter_Binuptime Function is both external and inlined: _Timecounter_Bintime Function is both external and inlined: _Timecounter_Getboottimebin Function is both external and inlined: _Thread_Priority_perform_actions Function is both external and inlined: _Thread_Priority_perform_actions Function is both external and inlined: _Thread_Clear_state_locked Function is both external and inlined: _Thread_Clear_state_locked Function is both external and inlined: _Thread_Clear_state_locked Function is both external and inlined: _Thread_Clear_state_locked Function is both external and inlined: _Malloc_System_state Function is both external and inlined: _Malloc_System_state Function is both external and inlined: _Malloc_System_state Function is both external and inlined: rtems_counter_initialize_converter Function is both external and inlined: rtems_counter_initialize_converter Function is both external and inlined: rtems_version_minor Function is both external and inlined: _Heap_Get_first_and_last_block Function is both external and inlined: _Heap_Get_first_and_last_block Error while running sparc-rtems6-objdump on /home/yoman/RTEMS/src/rtems/build/sparc/gr712rc/testsuites/validation/ts-validation-0.exe Objdump error in generating objdump Coverage time: 0:00:01.085511 Coverage generating reports Coverage analysis finished: /home/yoman/RTEMS/rtems/6/bin` I've tried to do a fresh VM fresh RTEMS build, results are exactly the same. It seems like it's something to do with `objdump`? That would explain the generated report containing only unreferenced symbols. Any tips on what's wrong or where to start looking to try and fix it? I wanted to generate coverage reports for the tests I developed, but not sure if there's any other way than through making this part work. Thanks and all the best!
