[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH 07/22] tools/utils: merge contents of libxlu_cfg_i.h to libxlu_cfg_y.y
Bison has added the ability to emit declarations in its header. As such
everything can instead be dumped in Bison's header instead of having a
private one.
This resolves the mixed up situation with the libxlu headers. Problem is
libxlu_cfg_i.h was trying to function as a wrapper for libxlu_cfg_y.h.
Issue is libxlu_cfg.c's #include order didn't match and thus everything
was fragile.
Fixes: b104c3762d ('Replace config file parser for "xl"')
Signed-off-by: Elliott Mitchell <ehem+xen@xxxxxxx>
---
The bug @b104c3762d was the incorrect ordering of #includes in
libxlu_cfg.c. It should instead have been:
#include "libxlu_cfg_i.h"
#include "libxlu_cfg_l.h"
Had this bug not been present, later commits might have looked deeper and
chosen correct solutions. Instead this resulted in all the ripples which
this series fixes.
I'm unsure whether Bison had implemented the %code feature by this point
in time.
The one and a half remaining issues are whether to convert the %{ %}
section to %code and move it after the %union. The %union construct ends
up in libxlu_cfg_y.h, whereas the %{ %}/%code construct ends up in
libxlu_cfg_y.c.
