From 3e7a84eeccc3b3a9b43c6dfb52bd98ea5acebf0a Mon Sep 17 00:00:00 2001 From: Taylor Simpson Date: Sun, 7 Feb 2021 23:46:24 -0600 Subject: Hexagon build infrastructure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add file to default-configs Add hexagon to meson.build Add hexagon to target/meson.build Add target/hexagon/meson.build Change scripts/qemu-binfmt-conf.sh We can build a hexagon-linux-user target and run programs on the Hexagon scalar core. With hexagon-linux-clang installed, "make check-tcg" will pass.
