Subject: [PATCH] BaseTools: Add -ffat-lto-objects option in GCC5 tool chain
Date: Wed, 19 May 2021 10:27:04 +0800 [thread overview]
Message-ID: <20210519022704.309-1-gaoliming@byosoft.com.cn> (raw)
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3403
This option can trig the uninitialized warning when lto is enabled.
The image size data is also collected for OVMF. There is no impact.
