[[PATCH] 1/3] aarch64: Sanitize access to cfun in aarch64_declare_function_name()

[Christoph Müllner]

From: Christoph Muellner <christoph.muell...@theobroma-systems.com>

It is possible to call aarch64_declare_function_name() and
have cfun not set. Let's sanitize the access to this variable.

gcc/

    * config/aarch64/aarch64.c (aarch64_declare_function_name):
    Santize access to cfun.
