484 # Expect does something very strange when it receives a single braced
485 # argument. It splits it along word separators and performs substitutions.
486 # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is
487 # evaluated as "\[ab\]". But that's not how TCL normally works; inside a
488 # double-quoted list item, "\[ab\]" is just a long way of representing
489 # "[ab]", because the backslashes will be removed by lindex.
491 # Unfortunately, there appears to be no easy way to duplicate the splitting
492 # that expect will do from within TCL. And many places make use of the
493 # "\[0-9\]" construct, so we need to support that; and some places make use
494 # of the "[func]" construct, so we need to support that too. In order to
495 # get this right we have to substitute quoted list elements differently
496 # from braced list elements.
498 # We do this roughly the same way that Expect does it. We have to use two
499 # lists, because if we leave unquoted newlines in the argument to uplevel
500 # they'll be treated as command separators, and if we escape newlines
501 # we mangle newlines inside of command blocks. This assumes that the

1826 # Use this function to keep your test scripts independent of the
1827 # exact line numbering of the source file. Don't write:
1829 # send_gdb "break 20"
1831 # This means that if anyone ever edits your test's source file,
1832 # your test could break. Instead, put a comment like this on the
1833 # source file line you want to break at:
1835 # /* breakpoint spot: frotz.exp: test name */
1837 # and then write, in your test script (which we assume is named
1840 # send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n"
1842 # (Yes, Tcl knows how to handle the nested quotes and brackets.

1852 # The previous implementation of this procedure used the gdb search command.
1853 # This version is different:
1855 # . It works with MI, and it also works when gdb is not running.
1857 # . It operates on the build machine, not the host machine.
1859 # . For now, this implementation fakes a current directory of
1860 # $srcdir/$subdir to be compatible with the old implementation.
1861 # This will go away eventually and some callers will need to
1864 # . The TEXT argument is literal text and matches literally,
1865 # not a regular expression as it was before.
1867 # . State changes in gdb, such as changing the current file
1868 # and setting $_, no longer happen.

1871 # old implementation.
