From 31a726122f6bf07b56341144465964fe342ec614 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sun, 3 Sep 2017 11:22:16 +0200 Subject: [PATCH] arch: add option to disable internal toolchain backend Some architectures or specific cores do not have support in upstream gcc. Currently, they are individually listed as exclusions in the toolchain choice. This poses a maintainance burden, as the knowledge about what gcc version supports what architecture is split across many places: the toolchain choice, the gcc version choice, the external toolchains. As a first step, add a blind option that architectures or individual cores may select to indicate they lack support in our internal backend. Actual use of the option will come in followup patches.
