Subject: Re: [PATCH v7 11/15] perf annotate-arm64: Support 'mov' instruction tracking
Date: Tue, 13 Oct 2026 13:45:44 +0000 [thread overview]
Message-ID: <sashiko-outbox-169859@kernel.org> (raw)
In-Reply-To: <9e8a4f59ac1750e136795fbd58aa6613dab30f93.1791629326.git.wutengda@huaweicloud.com>
> Extend update_insn_state_arm64() to support register-to-register and
> immediate-to-register 'mov' instructions.
>
> For register-to-register 'mov' (e.g., mov dreg, sreg), propagate data type
> information from the source register to the destination register.
>
> For immediate-to-register 'mov' (e.g., mov dreg, #imm), store the immediate
> value in the destination register's imm_value field and set its kind to
> TSR_KIND_CONST, allowing subsequent instructions to resolve it as a
> constant.
>
> A real-world example is shown below:
>
> ffff8000803eebf8 <get_vma_policy>:
> ffff8000803eec20: mov x21, x0 // x0 (struct vm_area_struct*) -> x21
> [ ... ]
> found by insn track: 0x98(reg21) type-offset=0x98
> final result: type='struct vm_area_struct' size=0xb0
