[edk2-devel] [PATCH v1 1/1] BaseTools: don't use WHOLEARCHIVE linker flag for VS2017 toolchain

[Roman Agafonov]

Hi Liming,

Sure. Here is what I get after building our NIC driver binary with VS2015x86 and VS2017 toolchains:

pcfist at pcfist-pc:/mnt/c/src/uefi/udk2018$ du -h Build/xgbe_atl/RELEASE_VS2015x86/X64/xgbe_atl.efi Build/xgbe_atl/RELEASE_VS2017/X64/xgbe_atl.efi
36K     Build/xgbe_atl/RELEASE_VS2015x86/X64/xgbe_atl.efi
68K     Build/xgbe_atl/RELEASE_VS2017/X64/xgbe_atl.efi

Best regards,
Roman

Can you show the size data with VS2017 and VS2015 for the same code?

Thanks
Liming
