[-- Attachment #1: Type: text/plain, Size: 11468 bytes --]

Hi,

I am going to attempt to organize the possible MI exec async output
commands. The current problem is that it is not easy to understand the
possible number of 'exec async output commands' that GDB/MI can return
to the FE. I would like to simply this, and eventually add a testcase
for each case. This is a start at enumerating all of the case's and
giving the user a minimal amount of information.

The design is to have mi-common.h be the interface to the rest of 
GDB. Also, MI developers can have a place to look at to determine all
possible supported command types.

Eli, if you can think of a better way for me to add to the doco, let me
know.

BTW, someone please tell me if the testsuite diff is OK, for some reason
there are minor differences between a fresh checkout and my patched
tree, although, I think it has nothing to do with my changes.

I've attached the added files and the testsuite diff. The patch is
below.

2005-03-24  Bob Rossi  <bob@brasko.net>
        * Makefile.in (SUBDIR_MI_OBS, SUBDIR_MI_SRCS): Add mi-common
        (gdb/mi/ headers): Add mi_common_h
        (breakpoint.o, infrun.o): Add dependencies mi_common_h
        * breakpoint.c (include): Add include 'mi/mi-common.h'
        (print_it_typical): Use async_reason_lookup
        (watchpoint_check): ditto
        * infrun.c (include): Add include 'mi/mi-common.h'
        (print_stop_reason): Use async_reason_lookup

2005-03-24  Bob Rossi  <bob@brasko.net>

        * gdb.texinfo (GDB/MI Out-of-band Records): Add bullet enumerating
        the possible reasons why an exec async record would be returned to FE.

Thanks,
Bob Rossi
