Since https://github.com/ARM-software/acle/pull/276 the ACLE defines attributes to better describe the use of a given SME state. Previously the attributes merely described the possibility of it being 'shared' or 'preserved', whereas the new attributes have more semantics and also describe how the data flows through the program. For ZT0 we already had to add new LLVM IR attributes: * aarch64_new_zt0 * aarch64_in_zt0 * aarch64_out_zt0 * aarch64_inout_zt0 * aarch64_preserves_zt0 We have now done the same for ZA, such that we add: * aarch64_new_za (previously `aarch64_pstate_za_new`) * aarch64_in_za (more specific variation of `aarch64_pstate_za_shared`) * aarch64_out_za (more specific variation of `aarch64_pstate_za_shared`) * aarch64_inout_za (more specific variation of `aarch64_pstate_za_shared`) * aarch64_preserves_za (previously `aarch64_pstate_za_shared, aarch64_pstate_za_preserved`) This explicitly removes 'pstate' from the name, because with SME2 and the new ACLE attributes there is a difference between "sharing ZA" (sharing the ZA matrix register with the caller) and "sharing PSTATE.ZA" (sharing either the ZA or ZT0 register, both part of PSTATE.ZA with the caller).
