slowpath-aarch64-port inital
Browse files Browse the repository at this point in the history 
AArch64 port of drmemory.

Only contains slowpath support with shared_slowpath off.

Pattern mode and fastpath modes are being worked on separately.

Currently this build does break some x86 functionality.

Depends on:
https://github.com/DynamoRIO/dynamorio/tree/mem-ref-for-clean-calls-aarch64/core

Current tests we have analysed:
