You probably have an issue with the versions of gdb or qemu you are using, since I was not able to reproduce your problem with a version 10.1 of aarch64-elf-gdb and a version 6.2.0 of qemu-system-aarch64 compiled from scratch on an Ubuntu 20.04.3 LTS system:

Is array different w/ and w/o GCC aligned attribute in rpi3?

Asked 2021-Jul-15 at 07:08

Currently I'm tracing the example of rpi3 mailbox and I found something weird. According to wiki:

The buffer itself is 16-byte aligned as only the upper 28 bits of the address can be passed via the mailbox.

and I found the code might be relative with the description:

Is array different w/ and w/o GCC aligned attribute in rpi3?

Well, no, the array itself is not different, only the placement of the whole array is affected.

If you want like array elements to be aligned, do an array of aligned structures.

I found it's 4 bytes aligned

Sure, elements of the array are 4 bytes aligned - looks like int has 4 bytes on your platform.

My question is what is the purpose of this attribute in here

To make the array mbox aligned to 16, not its elements.

did it matter?

Yes.
