我注意到可执行文件的大小变得比armhf 上的大。我查看了 - 现在的最小值int main (int argc, char **argv) {return 0;}（在 gcc -Wall mini.c -o mini; strip mini 之后）约为 67 KB，其中约 64 KB 被零填充。
我怀疑编译器本身不应该受到指责，因为如果你得到 mini.o，那么它的大小约为 1200 字节。
完全是这样的：
root@orangepizero2w:~/test# cat mini.c
int main (int argc, char **argv) {
return 0;
}
root@orangepizero2w:~/test# gcc -o mini mini.c
root@orangepizero2w:~/test# strip mini
root@orangepizero2w:~/test# ls -l mini
-rwxr-xr-x 1 root root 67592 ноя 15 13:29 mini
root@orangepizero2w:~/test# ldd mini
linux-vdso.so.1 (0x0000ffff9157f000)
libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffff91370000)
/lib/ld-linux-aarch64.so.1 (0x0000ffff91542000)
root@orangepizero2w:~/test# gcc -c -o mini.o mini.c
root@orangepizero2w:~/test# ls -l
итого 76
-rwxr-xr-x 1 root root 67592 ноя 15 13:29 mini
-rw-r--r-- 1 root root 50 ноя 15 13:21 mini.c
-rw-r--r-- 1 root root 1272 ноя 15 13:30 mini.o
root@orangepizero2w:~/test#
问题：为什么？最重要的是——为什么？而在没有无条件预留64KB的情况下之前又是如何工作的呢？
更新：我试图查看 objdump，但我对此一无所知：
