28 # They should be tested with both M-? and TAB.
30 # "show output-" "radix"
31 # "show output" "-radix"
32 # "p" ambiguous (commands starting with p--path, print, printf, etc.)
33 # "p " ambiguous (all symbols)
34 # "info t foo" no completions
35 # "info t " no completions
36 # "info t" ambiguous ("info target", "info terminal", etc.)
37 # "info ajksdlfk" no completions
38 # "info ajksdlfk " no completions
40 # "info " ambiguous (all info commands)
41 # "p \"break1" unambiguous (completes to filename "break1.c")
42 # "p \"break1." unambiguous (should complete to "break1.c" but does not,
43 # due to readline limitations)
44 # "p 'a" ambiguous (all symbols starting with a)
45 # "p b-a" ambiguous (all symbols starting with a)
46 # "p b-" ambiguous (all symbols)
47 # "file Make" "file" (word break hard to screw up here)
48 # "file ../gdb.stabs/we" "ird" (needs to not break word at slash)

482 # Unfortunately, on some systems, there are .o files in system
483 # libraries which declare static variables named `b'. Of course,
484 # those variables aren't really in scope, as far as the compiler is
485 # concerned. But GDB deliberately tries to be more liberal: if you
486 # enter an identifier that doesn't have any binding in scope, GDB will
487 # search all the program's compilation units for a static variable of
490 # This behavior can help avoid a lot of pedantry, so it's usually a
491 # good thing. But in this test case, it causes GDB to print the value
492 # of some random variable, instead of giving us the "No symbol..."
493 # error we were expecting.
495 # For example, on S/390 linux, the file s_atan.c in libm.a declares a
496 # `b', which is a structure containing an int and a float, so GDB says
497 # ``Argument to arithmetic operation not a number or boolean'' instead
498 # of ``No symbol ...''.
500 # So, I'm hoping that there is no system with a static library variable named
501 # `no_var_by_this_name'.

627 # this happens, readline tries to manage things, producing output that
628 # may make sense on the screen, but is rather hard for our script to
631 # In the case that motivated this change, the (gdb) prompt occupied
632 # the leftmost six columns, and `${objdir}/' was seventy-four
633 # characters long --- eighty in all. After printing the slash,
634 # readline emitted a space, a carriage return, and then `Makefile'
635 # (the tab character being received as input after `Make'.
637 # Basically, you have to let readline do whatever it's going to do to
638 # make the screen look right. If it happens to use a different
