--- Comment #46 from ard.biesheuvel at linaro dot org ---
One issue that this causes, which I did not see mentioned anywhere in the
thread, is that the use of adrp/add and adrp/ldr imposes a 4 KB section
alignment. In EDK2 Tianocore (UEFI reference implementation), we deliberately
use -mcmodel=large to get around this requirement, since code size is a big
deal when executing from NOR flash, and the architecture of EDK2 (lots and lots
of small separately linked binaries) makes
the overhead of 4 KB section alignment prohibitive. (It uses 32 byte section
alignment unless there are objects like a vector table that require more)
