This is normal behaviour when configuring with --enable-cpuhistory, serves as a reminder to us that CPU history recording hasn't been properly implemented for those machines. (Compyx, 2019-11-19)

IWYU - include-what-you-use

IWYU (https://github.com/include-what-you-use/include-what-you-use) is a tool that scans a codebase and reports on #include's that are used, might be missing and may not be needed. It should also report on forward declarations and maybe suggest using those (haven't figured that out yet).

It requires clang/llvm and building the actual tool from source using CMake. The instructions could be better and some stuff doesn't work quite right when following the instructions, but it can built and used (TODO: add instructions on how to properly build and use it (the instructions on copying clang's include/ are wrong and few deps on Debian are missing)).

Currently it has some false positives when using it on Gtk3-VICE: especially when it scans any Gtk3 code, it outputs a lot of extra #include's that aren't required, just #include'ing <gtk/gtk.h> will pull in all of the Glib, GIO, GObject, Atk, Pango, Cairo headers our Gtk3 UI requires.

As an example, here's a run on Gtk3-VICE on Linux which was configured with:

$ ../vice/configure --enable-native-gtk3ui --enable-debug-gtk3ui --enable-debug --enable-ethernet --with-pulse --with-alsa --with-jpeg --with-png --with-gif --enable-x64

The resulting report is 1.7MB of plain text, so I put it on my DropBox: https://www.dropbox.com/s/rr0v8nz3xyx8dn7/iwyu-clang6-vice-r36405.log?dl=0
