Subject: Re: [PATCH] BaseTools/tools_def: add CLANG38 LTO versions for AARCH64 and ARM
Date: Thu, 7 Dec 2017 02:05:46 +0000	[thread overview]
Message-ID: <06C8AB66E78EE34A949939824ABE2B313B5E441A@shsmsx102.ccr.corp.intel.com> (raw)
In-Reply-To: <20171206113917.6166-1-ard.biesheuvel@linaro.org>

Hi Ard,
I'm OK for the patch.
BTW, would you mind to help add the "-Wno-unused-const-variable" in the CLANG38_WARNING_OVERRIDES? I happen to need add it in CLANG38 (https://bugzilla.tianocore.org/show_bug.cgi?id=790) and I see it seems a shared flag for ARM/AARCH64 as well.
