I've just tried the following to compare make logs of before commit 8aba9dceebb14144e07d19593111ee3a999c37fc on the one hand and after this commit and with the proposed fix on the other hand: git checkout 8aba9dceebb14144e07d19593111ee3a999c37fc^ (that's the commit just before the one which split LD_FLAGS) make distclean ; make edminiv2_config; make > ~/old.txt 2>&1 git checkout 8aba9dceebb14144e07d19593111ee3a999c37fc (that's the commit which split LD_FLAGS) (replace "PLATFORM_LDFLAGS += -pie" with "LDFLAGS_u-boot += -pie" in arch/arm/config.mk) make distclean ; make edminiv2_config; make > ~/new.txt 2>&1 (and finally) kdiff3 ~/old.txt ~/new.txt The only difference I see between the make logs is the relative location of the -pie option in the final ld invocation: in the 'old' case options go ... -Bstatic -T u-boot.lds -pie -Ttext ... whereas in the 'new' case, they go ... -pie -Bstatic -T u-boot.lds -Ttext ... So I think the binary should be pretty much the same in the 'old' and 'new' cases, and that should be irrespective of the tool chain.

Also running a diff over the System.map and u-boot.map files is usually a good and easy test that images are identical.

I think I understood you: what I do is compile without commit 8aba9dce on the one hand, and with it _plus Stefano's patch_ on the other hand, in order to see how things compiled before we split LDFLAGS (8aba9dce^) with how things compile if we split LDFLAGS (8aba9dce) with -pie in the right place (Stefano's patch).

Sorry, again. While hunting another problem I've applied Stefano's patch but haven't had 8aba9dceebb14144e07d19593111ee3a999c37fc (I was on the wrong branch here).
