From e21e355e2ca7fefb15b4df7078f995d3fb9c2b89 Mon Sep 17 00:00:00 2001 From: Liming Gao Date: Thu, 11 Jan 2018 17:05:15 +0800 Subject: [PATCH] UefiCpuPkg: Update PiSmmCpuDxeSmm pass XCODE5 tool chain https://bugzilla.tianocore.org/show_bug.cgi?id=849 In V2, use "mov rax, strict qword 0" to replace the hard code db. 1. Use lea instruction to get the address instead of mov instruction. 2. Use the dummy address as jmp destination, and add the logic to fix up the address to the absolute address at boot time. 3. On MpFuncs.nasm, use ExchangeInfo to record InitializeFloatingPointUnits. This way is same to MpInitLib.
