https://community.arm.com/support-forums/f/compilers-and-libraries-forum/53354/arm-gnu-toolchain-11-3-rel1-missing-gcov_-symbols
   
   $ arm-none-eabi-gcc -v
   ```
   ...
   gcc version 11.3.1 20220712 (Arm GNU Toolchain 11.3.Rel1)

   $ cat main.c
   ```
   int __start(void)
   {
     return 0;
   }
   ```
   
   Compiler with arm GCC-11.3:

-fomit-frame-pointer -fprofile-generate \ -ftest-coverage -mthumb --coverage 
-fno-common -Wall -Wshadow -Wundef -ffunction-sections -fdata-sections -g \ 
-mlittle-endian -mcpu=cortex-m0 -mthumb -mfloat-abi=soft main.c -o main.o
   ```
   
   ```
   $ arm-none-eabi-ld --entry=__start -nostdlib --gc-sections 
-Tpimoroni-tiny2040-flash.ld -o test_gcov --start-group main.o \ 
~/gcc/linux/arm/bin/../lib/gcc/arm-none-eabi/11.3.1/thumb/v6-m/nofp/libgcov.a 
--end-group arm-none-eabi-ld: main.o: in function `__start':
