[PATCH] Fix gdb.mi/mi-file.exp for stubs.

[Pedro Alves <pedro_alves@portugalmail.pt>]

[-- Attachment #1: Type: text/plain, Size: 1006 bytes --]

Hi all,

There is a comment on mi-file.exp that says:

    # get the path and absolute path to the current executable
    #
    # In gdb 6.2 (at least), the default line number is set by
    # select_source_symtab to the first line of "main" minus
    # the value of "lines_to_list" (which defaults to 10) plus one.
    # --chastain 2004-08-13

That won't work for remote stubs.

The attached patch adds a call to mi_run_to_main with the following comment:

  # When debugging a stub, we can't depend on the current file
  # being the default file set by select_source_symtab.
  # When the gdb host connects to the stub, the stub will already be
  # running the target program stopped at a function
  # that probably isn't the one with main. We force
  # the file with main to be the current, so the following tests work.

Please review and commit.

Cheers,
Pedro Alves

       * gdb.mi/mi-file.exp: Call mi_run_to_main if use_gdb_stub is set.
