Hi all:
hello.c --- int main(void) { return (0);}
gcc hello.c
size a.exe
text data bss dec hex filename
1024 1024 12 2060 80c a.exe
arm-elf-gcc xxxxxxx hello.c xxxxxx (no debug option -g not listed)
arm-elf-size a.out
text data bss dec hex filename
206540 7484 180644 394668 605ac a.out
Why so much different??? It seems that the arm-elf-gcc output is much larger
that the gcc output. How can I get the actual size of the app for the arm? I
convert it to binary by using arm-elf-objcopy -O binary a.out b, I got b
200KB , how come? Is it possible for just for a plain main function? Is
there any way to get the size of each section for the binary file?
Thanks a lot
james
