Subject: Re: [PATCH v6 19/26] perf annotate-data: Track imm_value for stack variables
Date: Wed, 16 Sep 2026 01:44:11 +0000 [thread overview]
Message-ID: <20260916014411.8F9F91F000FF@smtp.kernel.org> (raw)
In-Reply-To: <8b29a11ea56bdc9973e3ab65d6f5ebdea0927bfa.1789521520.git.wutengda@huaweicloud.com>
> Currently, imm_value is tracked in registers but dropped when values
> are saved to or loaded from stack variables during type profiling.
> If a register of type TSR_KIND_CONST is stored to the stack, its value
> will be lost.
>
> Add an imm_value field to struct type_state_stack and update
> set_stack_state() and findnew_stack_state() to accept and preserve the
> immediate value when updating stack state.
