The implementation of shadow call stack on aarch64 is quite different to the implementation on x86_64. Instead of reserving a segment register for the shadow call stack, we reserve the platform register, x18. Any function that spills lr to sp also spills it to the shadow call stack, a pointer to which is stored in x18. Differential Revision: https://reviews.llvm.org/D45239 llvm-svn: 329236 show more ...
