Date: Mon Sep 13 10:43:04 2021 -0700 # # Merge branch 'gcc-min-version-5.1' (make gcc-5.1 the minimum version) # # Merge patch series from Nick Desaulniers to update the minimum gcc # version to 5.1. # # This is some of the left-overs from the merge window that I didn't want # to deal with yesterday, so it comes in after -rc1 but was sent before. # # Gcc-4.9 support has been an annoyance for some time, and with -Werror I # had the choice of applying a fairly big patch from Kees Cook to remove a # fair number of initializer warnings (still leaving some), or this patch # series from Nick that just removes the source of the problem. # # The initializer cleanups might still be worth it regardless, but # honestly, I preferred just tackling the problem with gcc-4.9 head-on. # We've been more aggressiuve about no longer having to care about # compilers that were released a long time ago, and I think it's been a # good thing. # # I added a couple of patches on top to sort out a few left-overs now that # we no longer support gcc-4.x. # # As noted by Arnd, as a result of this minimum compiler version upgrade # we can probably change our use of '--std=gnu89' to '--std=gnu11', and # finally start using local loop declarations etc. But this series does # _not_ yet do that. # # Link: https://lore.kernel.org/all/20210909182525.372ee687@canb.auug.org.au/ #
