Subject: Re: [PATCH 3/3] BaseTools GCC/ARM: add -fno-builtin to CC flags
Date: Thu, 4 Aug 2016 18:01:05 +0200	[thread overview]
Message-ID: <CAN9vWDJoe8kGqRn3j00N=KP0UaL7SgzTvHG+WjZi+8CO9uYPig@mail.gmail.com> (raw)
In-Reply-To: <1470321767-26921-4-git-send-email-ard.biesheuvel@linaro.org>

not directly related but could we add nostdinc too? At least for my
platform that works perfectly and it prevents you from accidentally
including any libc/libgcc/whatever headers from your toolchain.(nostdlib is
already enabled)

Thanks
Michael
