Re: [PATCH v7 10/15] perf annotate-arm64: Support stack variable tracking

[sashiko-bot@kernel.org]

> Extend update_insn_state_arm64() to track data types stored on the
> stack.
> 
> The implementation handles:
> 1. Stack Loads: Identify when a register is loaded from a stack
>    slot and update the register's type state based on the tracked
>    stack content or compound member types.
> 2. Stack Stores: Update or create new stack state entries when
>    a tracked register type is stored to the stack.
> 
> Similar to loads, stores also support saving one or two registers
> (in the case of 'stp'). Therefore, propagate_store_reg_state() is
> introduced.
> 
> With these changes, the instruction tracker can now follow data types
> as they move between registers and memory, specifically for function
> local variables and compiler-spilled values on arm64.
