GCC size output when compiled for ARM:
- $ arm-none-eabi-gcc -Os -c aes.c -o aes.o
- $ size aes.o
- text data bss dec hex filename
- 1079 0 204 1283 503 aes.o

-And if we're compiling for the Thumb ISA:

- $ arm-none-eabi-gcc -O2 -c -mthumb aes.c -o aes.o
- $ size aes.o
- text data bss dec hex filename
- 856 0 204 1060 424 aes.o

-Somehow, -O2 is a bit smaller than -Os with this compiler. I am using Mentor Graphics ARM toolchain:
