It fails for me with arm-linux-gnueabihf-gcc-11 (gcc version 11.4.0
(Ubuntu 11.4.0-1ubuntu1~22.04)).

$ arm-linux-gnueabihf-as -v
GNU assembler version 2.38 (arm-linux-gnueabihf) using BFD version
(GNU Binutils for Ubuntu) 2.38

In response to v1, you replied:

| That ultimately depends on binutils support for SHF_GNU_RETAIN (2.36+).

So binutils 2.38-4ubuntu2.6 is sufficiently new, but it doesn't work?
