From 9842ceae9fa8deae141533d52a6ead7666962c09 Mon Sep 17 00:00:00 2001 From: Pratyush Anand Date: Wed, 2 Nov 2016 14:40:46 +0530 Subject: arm64: Add uprobe support This patch adds support for uprobe on ARM64 architecture. Unit tests for following have been done so far and they have been found working 1. Step-able instructions, like sub, ldr, add etc. 2. Simulation-able like ret, cbnz, cbz etc. 3. uretprobe 4. Reject-able instructions like sev, wfe etc. 5. trapped and abort xol path 6. probe at unaligned user address. 7. longjump test cases Currently it does not support aarch32 instruction probing.
