> This works fine when compiling under risc-v with the -g arch, such as rv32gc or rv64gc. However, depending on the vintage of the compiler, it does not work when compiling with an arch such as riscv32imac.

Regarding "depending on the vintage of the compiler" : My understanding is that only the latest one or two major releases of Clang and the latest Clang is officially supported.
So we shouldn't worry about the old versions. They are simply unsupported.
