However with version 11.4.0 we did see a '.gcda:stamp mismatch with notes file' while running gcov tool. The same command goes fine with the previous branch code which uses gcc 10.3.0. Example would be like : <toolchain-path>/gcov -l src-file.c -o ./src-file-obj-dir-path src-file.gcda:stamp mismatch with notes file File 'src-file.c' Lines executed:0.00% of 36 Creating 'src-file.c.gcov' File '../../abcd/ef/hijk.h' Lines executed:0.00% of 2 Creating 'src-file.c##hijk.h.gcov' File '../include/lmno.h' Lines executed:0.00% of 2 Creating 'src-file.c##lmno.h.gcov' Lines executed:0.00% of 40 This is seen for several files in the new branch of code where gcc v11.4.0 is used and not seen with older branch where the gcc version is 10.3.0. We generate the gcov based image (compiled with --coverage in CFLAGS) , load the image on the device, do testing, collect gcda files from device and put it back in the same obj-dir location and run the gcov tool to get the gcov files (eg :src-file.c.gcov). We checked the time stamp of gcda vs gcno files and even then the issue was seen. Was there any specific enhancement with 11.x version which would be causing the issue or is there any further check to be done during the compilation with --coverage or during the gcov tool run ? Due to my organisation restriction, I'm not able to give more info on the file names used and the make file info but I can try the best to get the info for your understanding. Awaiting valuable reply. Thank you team for your support always !
