This addresses a test failure introduced in 4f6cf2c2072ccf5780ac30bf69ebf99b788dbd52. `0x1122334455667788` is a non-canonical address on x86_64 (fails to write to rsp) and gets its non-addressing bits masked off on read for pc/lr/sp/fp on Darwin AArch64, so it doesn't round-trip on either. Zero the top 20 bits to stay clear of both. >From 56fb7ff73e7f4af9c660e128c7ae8e3366310bbc Mon Sep 17 00:00:00 2001 From: Med Ismail Bennani <[email protected]> Date: Sun, 2 Aug 2026 23:50:23 -0700 Subject: [PATCH] [lldb] Fix test_case_insensitivity's register value for canonical/PAC constraints 0x1122334455667788 is a non-canonical address on x86_64 (fails to write to rsp) and gets its non-addressing bits masked off on read for pc/lr/sp/fp on Darwin AArch64, so it doesn't round-trip on either.
