Subject: [PATCHv2 6/8] arm64: asm-offsets: add S_FP
Date: Tue, 29 Oct 2019 16:58:30 +0000 [thread overview]
Message-ID: <20191029165832.33606-7-mark.rutland@arm.com> (raw)
In-Reply-To: <20191029165832.33606-1-mark.rutland@arm.com>
So that assembly code can more easily manipulate the FP (x29) within a
pt_regs, add an S_FP asm-offsets definition.
