For simplicity, I have created a GDB test which you can use for validation if
you like:

# Used to catch regression where GDB would expand CU table when printing
# fundamental types that are in "mixed-case".

if {[prepare_for_testing "failed to prepare" $testfile \
         [list $srcfile $srcfile2] {debug nowarnings}]} {
    return -1
}

set readnow_p [readnow]

# The command we test here produce many lines of output; disable "press
# <return> to continue" prompts.
gdb_test_no_output "set height 0"

gdb_file_cmd ${binfile}

# Check no CU are currently read before starting the program
gdb_test "maint print statistics" \
    ".*Number of read CUs: 0.*" \
    "No CU are read at the start"

gdb_test "print INT" "" "printing uppercase fundamental type"

# Now check CUs have still not been read after printing
gdb_test "maint print statistics" \
    ".*Number of read CUs: 0.*" \
    "No CU are read after printing fundamental type"
