HINT #0x7 is XPACLRI which is one of the ARMv8.3 pointer authentication
instructions. This is where they went into binutils:

(which gives a helpful link to
https://community.arm.com/processors/b/blog/posts/armv8-a-architecture-2016-additions
if you want to know what pointer authentication is all about).
Since these HINT insns all NOP on CPUs before v8.3, gcc can happily use them
even if it's not specifically compiling for a v8.3 CPU.
