[Mesa-dev] [PATCH v3 0/7] Delay exec table initialization until version is computed

[Jordan Justen]

GLES3 support requires that the version be computed before the
exec table is initialized.

For main exec table initialization (api_exec.c):
* Rename _mesa_create_exec_table to _mesa_initialize_exec_table
* _mesa_initialize_context allocates the exec table, and sets
  entries to nop, but leaves functions otherwise uninitialized
* Drivers must now call _mesa_compute_version and then
  _mesa_initialize_exec_table

Similarly for VBO:
* _vbo_CreateContext no longer initializes VBO vtxfmt functions
* _mesa_initialize_vbo_vtxfmt was added, and drivers must now
  call this function after computing the version

v3:
 * VBO vtxfmt function programming must also be delayed until
   the version in computed.
 * Combined all driver changes into a single patch

v2:
 * Rather than move version computation earlier into
   _mesa_initialize_context, now _mesa_initialize_context will
   no longer initialize the exec dispatch table.
 * All drivers should now be modified, whereas in v1, only
   i965 and swrast were modified.

v1:
 * Implement support for swrast & i965 drivers

Jordan Justen (7):
  mesa: separate exec allocation from initialization
  vbo: add _mesa_initialize_vbo_vtxfmt
  drivers: compute version and then initialize exec table
  mesa dispatch_sanity: call new functions to initialize exec table
  mesa: don't initialize exec dispatch tables in
    _mesa_initialize_context
  mesa: don't initialize VBO vtxfmt in _vbo_CreateContext
  mesa: assert if driver did not compute the version
