调研方向

Reproduce the issue by opening binary views with different architectures in separate tabs and checking bv.arch and len(bv.arch.intrinsics) in the built-in Python interpreter. Trace how the active tab supplies bv.arch and its intrinsics; done means switching tabs updates both values to the associated binary view's architecture.

描述

Version and Platform (required):

  • Binary Ninja Version: 5.4.10292-dev Ultimate
  • OS: MacOS
  • OS Version: 26.5.2
  • CPU Architecture: M4 Max

bv.arch.intrinsics is locked to first seen architecture. Opening and switching to another tab with a different architecture binary view keeps the bv.arch.intrinsics from the first seen tab.

Steps To Reproduce:

  1. Open binary view in UI with architecture A
  2. Note the following in the built-in python interpreter:
>>> bv.arch
<arch: x86_64>
>>> len(bv.arch.intrinsics)
11930
  1. Open another binary view in a different tab with architecture B
  2. Note the following in the built-in python interpreter:
>>> bv.arch
<arch: x86_64>
>>> len(bv.arch.intrinsics)
11930

The above was repeated with x86, arm64 and hexagon combinations. Doesn't seem to be specific to an architecture.

Expected Behavior:
bv.arch.intrinsics is updated based on the binary view associated with the open tab.
