[PATCH v2 0/1] gdb, infcmd: Support jump command in multi-inferior case.

[PATCH v2 0/1] gdb, infcmd: Support jump command in multi-inferior case.

[Matti Puputti]

Thanks for the feedback on v1.

Changes in v2:
  - In linespec.h, updated comment to explain the new parameter
    search_pspace.

  - In jump.exp, updated to use prepare_for_testing.

  - In jump.exp, updated how bp_on_non_call and bp_on_call are set,
    updated regexes to use these two variables, and added disabling
    of BP $bp_on_non_call.

Br,
Matti Puputti

[PATCH v2 1/1] gdb, infcmd: Support jump command in multi-inferior case.

[Matti Puputti]

Fixes the issue where jump failed if multiple inferiors run the same source.

See the below example

    $ gdb -q ./simple
    Reading symbols from ./simple...
    (gdb) break 2
    Breakpoint 1 at 0x114e: file simple.c, line 2.
    (gdb) run
    Starting program: /temp/simple

    Breakpoint 1, main () at simple.c:2
    2         int a = 42;
    (gdb) add-inferior
    [New inferior 2]
    Added inferior 2 on connection 1 (native)
    (gdb) inferior 2
    [Switching to inferior 2 [<null>] (<noexec>)]
    (gdb) info inferiors
      Num  Description       Connection           Executable
      1    process 6250      1 (native)           /temp/simple
    * 2    <null>            1 (native)
    (gdb) file ./simple
    Reading symbols from ./simple...
    (gdb) run
    Starting program: /temp/simple

    Thread 2.1 "simple" hit Breakpoint 1, main () at simple.c:2
    2         int a = 42;
    (gdb) info inferiors
      Num  Description       Connection           Executable
      1    process 6250      1 (native)           /temp/simple
    * 2    process 6705      1 (native)           /temp/simple
    (gdb) jump 3
    Unreasonable jump request
    (gdb)

In this example, jump fails because the debugger finds two different
locations, one for each inferior.
Solution is to limit the search to the current program space.

Thanks for the fixes.  I have a couple of minor nits but I think this is
pretty much OK.

This line is now redundant as we unconditionally set a value below.

This line is a bit long.  Please wrap it somewhere.

I think s/there/hit/ in this comment.  When I read this I initially
expected the code to be deleting the breakpoint rather than just
disabling it.

Can delete one of the empty lines added here.

Again, only need a single blank line here.

We don't use the 'then' keyword, this should be written like this:

  if {![runto_main]} {

I don't think this perror call is needed here.  runto_main will already
emit a FAIL if something goes wrong.

This 'return 0' can be dropped.

With these fixed:

RE: [PATCH v2 1/1] gdb, infcmd: Support jump command in multi-inferior case.

[Puputti, Matti]

Hi Andrew,

Thank you for your review and (conditional) approval.
I have uploaded new patch to address your comments. In addition I did my
best to clean out some other empty lines and trailing '#' lines, too.
And finally, I updated the commit date.
I hope the new patch is good.

Patch 3: https://sourceware.org/pipermail/gdb-patches/2023-April/199095.html

As you surely have noticed, this is my very first patch series landing in GDB.
If you are ok with the latest patch, can you push it for me, as I don't have
write access?

I plan to upstream more patches in the future and would like to have
"write after approval" access.  Can you help me with that as well? 

Br,
Matti Puputti
