arm64_i.c
See attached test case. It seems that x86_64 allows the input argument to an
extended inline asm block to be a pointer to a static struct, but aarch64 does
not.
This pattern is used in the Linux kernel (as part of the static_key runtime
patching) and without support blocks landing asm goto support</pre>
