URL: https://github.com/llvm/llvm-project/commit/52528806579b445f627cd93ff8201a59265795e8 DIFF: https://github.com/llvm/llvm-project/commit/52528806579b445f627cd93ff8201a59265795e8.diff LOG: [AArch64] Ampere1 does not support MTE The initial support for the Ampere1 mistakenly signalled support for the MTE feature. However, the core does not include the optional MTE functionality. Update the target parser to not include MTE for Ampere1.
