Subject: 回复: [edk2-devel] [PATCH v5 1/2] MdePkg/Include: Add CET instructions to Nasm.inc
Date: Thu, 25 Feb 2021 09:53:06 +0800 [thread overview]
Message-ID: <005101d70b18$f672fa90$e358efb0$@byosoft.com.cn> (raw)
In-Reply-To: <CO1PR11MB4929B3125BA07C855917B3E6D2809@CO1PR11MB4929.namprd11.prod.outlook.com>
Mike:
We agree to increase nasm compiler version after the stable tag. If this fix wants to catch stable tag 202102, it has to use hard code DB in Nasm.inc.
Sheng:
If this fix doesn't need to catch stable tag 202102, you can directly send the patch with nasm command in Nasm.inc.
Thanks
