[v3] plugins: generate list of symbols automatically

[PATCH v3 0/3] plugins: generate list of symbols automatically

Posted by Pierrick Bouvier 2 weeks, 3 days ago

Now that meson build for plugins was merged, we can cleanup another part with
the symbols file.
It has to be kept in sync between the header (qemu-plugin.h) and the symbols
file. This has proved to be error prone and tedious.

We solve this by generating this list from header directly using a python
script. Dependencies are triggered correctly, and the file is regenerated if the
header is modified, as expected.

Pierrick Bouvier (3):
  plugins: add missing export for qemu_plugin_num_vcpus
  plugins: detect qemu plugin API symbols from header
  plugins: eradicate qemu-plugins.symbols static file

this failed to apply cleanly.

Sorry about that. The commit is correct but the patch context is 
incorrect. Fixed in v4.
