[PATCH] D98053: [mac/lld] Fix scale computation for vector ops in PAGEOFF12 relocations

[Shoaib Meenai via Phabricator via llvm-commits]

smeenai added inline comments.


================
Comment at: lld/MachO/Arch/ARM64.cpp:134
+    scale = base >> 30;
+    if (scale == 0 && (base & 0x0480'0000) == 0x0480'0000) // vector op?
+      scale = 4;
----------------
If I'm reading the encoding table right (downloaded from https://developer.arm.com/documentation/ddi0487/ga/), then yup, this means a 128-bit operation.
