[RFC v12 59/65] target/arm: move sve_zcr_len_for_el to TARGET_AARCH64-on

[RFC v12 59/65] target/arm: move sve_zcr_len_for_el to TARGET_AARCH64-only cpu-sve |
Date: |
Fri, 26 Mar 2021 20:36:55 +0100 |
now that we handled the dependency between HELPER(), cpregs defs
and functions in tcg/,
we can make sve_zcr_len_for_el TARGET_AARCH64-only,
and move it to the cpu-sve module.
