还有 "step-out" / "step-over-instruction" 在 Simics 2021.24 中损坏?
Is "step-out" / "step-over-instruction" broken in Simics 2021.24?
Simics 2021.24 中的 Step-out 似乎被打破了。我做了“启用调试器”,但它仍然不起作用。请看下面:

因此您可以看到它调用了设置 rax 的位置,而不是跳过调用。
step-out 和 step-over-instruction 都需要调试信息。您可以使用 add-symbol-file 添加调试信息。
如果您没有调试信息,则必须设置断点或 运行 直到调用后的指令。在这种情况下,这将是以下之一:
bp.memory.run-直到-x地址=p:0x0dee41d1b
或
bp.memory.break-x地址=p:0x0dee41d1b
