You can compile a package containing a test procedure putting 123 into an Integer field of a record (tagged or not) and look at the assembler output.
With GNAT it's gcc -S -O2 test_pkg.adb
NB: the procedure probably needs to feed then an "out" parameter to prevent the compiler optimizing out completely the assignment with 123.
