[RFC PATCH v4 29/29] Hexagon build infrastructure |
Date: |
Mon, 28 Sep 2020 12:28:58 -0500 |
Add file to default-configs
Change configure
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.
