From 5511d3fa7db26bb6a132a5c3c2cd48d7a1322deb Mon Sep 17 00:00:00 2001 From: Kyrylo Tkachov Date: Fri, 18 May 2018 13:10:36 +0000 Subject: [PATCH] [arm][2/2] Remove support for -march=armv3 and older We deprecated architecture versions earlier than Armv4T in GCC 6 [1]. This patch removes support for architectures lower than Armv4. That is the -march values armv2, armv2a, armv3, armv3m are removed with this patch. I did not remove armv4 because it's a bit more involved code-wise and there has been some pushback on the implications for -mcpu=strongarm support. Removing armv3m and earlier though is pretty straightforward. This allows us to get rid of the armv3m and mode32 feature bits in arm-cpus.in as they can be assumed to be universally available. Consequently the mcpu values arm2, arm250, arm3, arm6, arm60, arm600, arm610, arm620, arm7, arm7d, arm7di, arm70, arm700, arm700i, arm710, arm720, arm710c, arm7100, arm7500, arm7500fe, arm7m, arm7dm, arm7dm are now also removed. Bootstrapped and tested on arm-none-linux-gnueabihf and on arm-none-eabi with an aprofile multilib configuration (which builds quite a lot of library configurations).
