This patchset introduces the idef-parser for target/hexagon. It's the eleventh iteration of the patchset and includes fixes suggested in previous iterations.
idef-parser is a build-time tool built using flex and bison. Its aim is to generate a large part of the tiny code generator frontend for Hexagon. The prototype of idef-parser has been presented at KVM Forum 2019 ("QEMU-Hexagon: Automatic Translation of the ISA Manual Pseudocode to Tiny Code Instructions"): https://www.youtube.com/watch?v=3EpnTYBOXCI target/hexagon/idef-parser/README.rst provides an overview of the parser and its inner working. Main changes in v11: * Patches 8, 9, and 10 adds our build-time dependencies flex, bison, and a native glib2 to the CI. These have not been reviewed. * Patch 12 has been added. It introduces some state in CPUHexagonState, and DisasContext necessary for idef-parser to deal with :mem_noshuf packets with a store in slot 1 and a predicated load in slot 0. * Patches 8 and 9 from v10 of the patchset have been dropped. These dealt with updating libvirt-ci and fixing renamed package templates, this is already taken care of in upstream. A couple of notes: * These commits build successfully on the CI (including using clang), with one notable exception. Presently, the build-user-hexagon job fails due to not being able to find flex/bison. This is due to the debian-hexagon-cross container not being built by the CI. As such the debian-hexagon-cross container will have to be manually rebuilt before merging. * checkpatch.pl complains about the _Generic macro OUT_IMPL in idef-parser/parser-helpers.h which we believe to be correctly formatted. The complaints concern the `:` in the type "labels" of the macro, and also the `default:` label.
