Invalid and baremetal platform values are reserved in https://github.com/ARM-software/abi-aa/blob/main/pauthabielf64/pauthabielf64.rst (constant names themselves are not defined there though). Regarding everything related to llvm_linux platform - it's not defined anywhere and I've defined it here since we need some sort of working ELF marking scheme to at least test things. If different constant names and/or values are preferred or there is some specification which needs to be updated correspondingly - please let me know.
