Hello, I have a question about data section contents.
Even if I don't allocate any variable in data section,
there is a certain amount of data section.
I compiled this file with intel-linux --> mn10300-elf
I didn't make any global variable here.
I compile this file with this command.
mn10300-elf-gcc -o test test.c -Tsim.ld
text data bss dec hex filename
3057 1848 12 4917 1335 test
There are 1848 bytes of data section. When I
disassemble test, I see _impure_data and _impure_ptr
labels in data section. What are these labels for?
