[PATCH 0/7] More cleanup of defs.h

[PATCH 0/7] More cleanup of defs.h

[Simon Marchi]

Some more cleanup of defs.h.  I tested this on the buildbot, but it's
very possible that it breaks the build on untested platforms.  If this
happens, the fix should be one include away.

Simon Marchi (7):
  gdb: move declarations of check_quit_flag and set_quit_flag to
    extension.h
  gdb: change return type of check_quit_flag to bool
  gdb: change type of quit_flag to bool
  gdb: move a bunch of quit-related things to event-top.{c,h}
  gdb: move annotation_level declaration/definition to annotate.{h,c}
  gdb: remove enum precision_type
  gdb: move symbol_file_command declaration to symfile.h

[PATCH 1/7] gdb: move declarations of check_quit_flag and set_quit_flag to extension.h

[Simon Marchi]

Move them out of defs.h, to extension.h, since the implementations are
in extension.c.

[PATCH 2/7] gdb: change return type of check_quit_flag to bool

[Simon Marchi]

Change the return type of the check_quit_flag function to bool.  Update
a few related spots.

[PATCH 4/7] gdb: move a bunch of quit-related things to event-top.{c,h}

[Simon Marchi]

Move some declarations related to the "quit" machinery from defs.h to
event-top.h.  Most of the definitions associated to these declarations
are in event-top.c.  The exceptions are `quit()` and `maybe_quit()`,
that are defined in utils.c.  For consistency, move these two
definitions to event-top.c.

Include "event-top.h" in many files that use these things.

[PATCH 5/7] gdb: move annotation_level declaration/definition to annotate.{h,c}

[Simon Marchi]

The declaration of annotation_level is currently in defs.h, while the
definition is in stack.c.  I don't really understand why that variable
would live in stack.c, it seems completely unrelated.  Move it to
annotate.c, and move the declaration to annotate.h.

Hi Alexandra,

Thanks for the review.  If you would like to get an acknowledgement for
your time spent reviewing or testing, you can reply with a tag such as:

Reviewed-By: Alexandra Petlanova Hajkova <ahajkova@redhat.com>

or

Tested-By: Alexandra Petlanova Hajkova <ahajkova@redhat.com>

You can also put both if you reviewed the code and did some testing.

The committer will then put these as git trailers in the commit message.

See: https://sourceware.org/gdb/wiki/ContributionChecklist#Receiving_positive_reviews

Simon
