Hello, We are in the process of upgrading our gcc toolchain to gcc 8.3 (from 7.3). In the process of doing that we have hit an error building edk2: make[2]: ***

Re: [edk2-devel] [edk2-discuss] WriteSections64()

Hello, Ard. The tools_def.txt was updated and both the -fno-pie and -fno-pic are specified when executing gcc. I don’t have access to the code at the moment but I will post the exact gcc command

Re: [edk2-devel] [edk2-discuss] WriteSections64()

Here is a sample of the gcc command line: "/x/sdk/sysroots/x86_64-pokysdk-linux/usr/bin/aarch64-poky-linux/aarch64-poky-linux-gcc" -I/x/edk2/edk2/MlxPlatformPkg/Include -march=armv8-a+crc -g

Re: [edk2-devel] [edk2-discuss] WriteSections64()

Your Conf/tools_def.txt is probably stale, and does not contain the -fno-pie option we added a while ago.

Re: [edk2-devel] [edk2-discuss] WriteSections64()

You are missing the -fno-unwind-tables option. Please make sure that you apply commit cbf00651eda6818ca3c76115b8a18e3f6b23eef4 to your tree.

Re: [edk2-devel] [edk2-discuss] WriteSections64()

Hi, Ard. I compared this output to my previous edk2 build (uses gcc 7.3) and noticed that the .eh_frame sections seem to be new with the gcc 8.3 compiler. I added -fno-exceptions and

Re: Some questions about UEFI

Hi Elena, (+cc Pete) .efi indicated an application (or driver), as opposed to a script. My go-to test case is a standalone GRUB executable. Generated with grub-mkstandalone -O arm64-efi -o

Re: LongJump.iii and Nasm.inc

Re: Some questions about UEFI

Hi Elena, hi Leif, I'll add the following comments: 1. Right now, the RPi3 firmware is set not to boot SD/USB by default, but boot into the UEFI Shell always. Therefore, if you want a
