Sry for the late reply but I tried your latest gcc-lto branch to make sure my answers are still correct. I tested it with all configurations(StdLib:X64/ARM, Ovmf:X64, ArmVirtPkg:ARM with both RELEASE and DEBUG). In StdLib are many warnings actually. That's because of -Wunused-const-variable and -Wmisleading-indentation. Also I had to apply the commit to fix 'Unsupported ELF EM_X86_64 relocation 0x4.' for X64.
'-b RELEASE -a ARM -t GCC5 -p AppPkg/AppPkg.dsc' is the only configuration I can't get to compile with gcc6(DEBUG works): /tmp/ccYJi1bO.ltrans0.ltrans.o: In function `memmove': <artificial>:(.text+0x3670): multiple definition of `memmove' /media/Data/repositories/git/efidroid/testing/linuxtoolchain/edk2/Build/AppPkg/RELEASE_GCC5/ARM/ArmPkg/Library/CompilerIntrinsicsLib/CompilerIntrinsicsLib/OUTPUT/CompilerIntrinsicsLib.lib(memmove.obj):(.text+0x0): first defined here /tmp/ccYJi1bO.ltrans0.ltrans.o: In function `memset': <artificial>:(.text+0x3674): multiple definition of `memset' /media/Data/repositories/git/efidroid/testing/linuxtoolchain/edk2/Build/AppPkg/RELEASE_GCC5/ARM/ArmPkg/Library/CompilerIntrinsicsLib/CompilerIntrinsicsLib/OUTPUT/CompilerIntrinsicsLib.lib(memset.obj):(.text+0x10): first defined here /media/Data/repositories/git/efidroid/prebuilts/gcc/linux-x86/arm/gcc-linaro-6.1.1~linaro-gcc-6-branch@f3888e76-20160721-x86_64_arm-eabi/bin/../lib/gcc/arm-eabi/6.1.1/../../../../arm-eabi/bin/ld: printf.obj: plugin needed to handle lto object /media/Data/repositories/git/efidroid/prebuilts/gcc/linux-x86/arm/gcc-linaro-6.1.1~linaro-gcc-6-branch@f3888e76-20160721-x86_64_arm-eabi/bin/../lib/gcc/arm-eabi/6.1.1/../../../../arm-eabi/bin/ld: puts.obj: plugin needed to handle lto object /media/Data/repositories/git/efidroid/prebuilts/gcc/linux-x86/arm/gcc-linaro-6.1.1~linaro-gcc-6-branch@f3888e76-20160721-x86_64_arm-eabi/bin/../lib/gcc/arm-eabi/6.1.1/../../../../arm-eabi/bin/ld: internal error /media/Data/repositories/git/abe/_build/snapshots/binutils-gdb.git~linaro_binutils-2_26-branch/ld/ldlang.c 6299 collect2: error: ld returned 1 exit status make: *** [GNUmakefile:417: /media/Data/repositories/git/efidroid/testing/linuxtoolchain/edk2/Build/AppPkg/RELEASE_GCC5/ARM/AppPkg/Applications/Main/Main/DEBUG/Main.dll] Error 1 Also, I only did compilation tests, I didn't try to run any of the produced binaries. this is the fixed branch: https://github.com/M1cha/edk2/commits/edk2-master-gcc6 it's based on your gcc5-lto-v6 branch.
