5 years agogdb: Show type summary for anonymous structures from c_print_typedef
Andrew Burgess [Fri, 12 Jul 2019 10:26:32 +0000 (11:26 +0100)]
gdb: Show type summary for anonymous structures from c_print_typedef

Currently each language has a la_print_typedef method, this is only
used for the "info types" command.

The documentation for "info types" says:

   Print a brief description of all types whose names match the regular
   expression @var{regexp} (or all types in your program, if you supply
   no argument).

However, if we consider this C code:

   typedef struct {
     int a;
   } my_type;

Then currently with "info types" this will be printed like this:

   3:      typedef struct {
       int a;
   } my_type;

I see two problems with this, first the indentation is clearly broken,
second, if the struct contained more fields then it feels like the
actual type names could easily get lost in the noise.

Given that "info types" is about discovering type names, I think there
is an argument to be made that we should focus on giving _only_ the
briefest summary for "info types", and if the user wants to know more
they can take the type name and plug it into "ptype".  As such, I
propose that a better output would be:

   3:      typedef struct {...} my_type;

The user understands that there is a type called `my_type`, and that
it's an alias for an anonymous structure type.

The change to achieve this turns out to be pretty simple, but only
effects languages that make use of c_print_typedef, which are C, C++,
asm, minimal, d, go, objc, and opencl.  Other languages will for now
do whatever they used to do.

The patch to change how anonymous structs are displayed also changes
the display of anonymous enums, consider this code sample:

   typedef enum {
     AA, BB, CC
   } anon_enum_t;

This used to be displayed like this:

   3:      typedef enum {AA, BB, CC} anon_enum_t;

Which will quickly become cluttered for enums with a large number of
values.  The modified output looks like this:

   3:      typedef enum {...} anon_enum_t;

Again, the user can always make use of ptype if they want to see the
details of the anon_enum_t type.

It is worth pointing out that this change (to use {...}) only effects
anonymous structs and enums, named types don't change with this patch,
consider this code:

   struct struct_t {
     int i;
   };
   enum enum_t {
    AA, BB, CC
   };

The output from 'info types' remains unchanged, like this:

   4:      enum enum_t;
   1:      struct struct_t;

An additional area of interest is how C++ handles anonymous types used
within a typedef; enums are handled basically inline with how C
handles them, but structs (and classes) are slightly different.  The
behaviour before the patch is different, and is unchanged by this
patch.  Consider this code compiled for C++:

   typedef struct {
     int i;
   } struct_t;

Both before and after this patch, this is show by 'info types' as:

   3:      typedef struct_t struct_t;

Unions are displayed similarly to structs in both C and C++, the
handling of anonymous unions changes for C in the same way that
it changes for anonymous structs.

I did look at ada, as this is the only language to actually have some
tests for "info types", however, as I understand it ada doesn't really
support typedefs, however, by forcing the language we can see what ada
would print.  So, if we 'set language ada', then originally we printed
this:

   3:      record
       a: int;
   end record

Again the indentation is clearly broken, but we also have no mention
of the type name at all, which is odd, but understandable given the
lack of typedefs.  If I make a similar change as I'm proposing for C,
then we now get this output:

   3:      record ... end record

Which is even less informative I think.  However, the original output
_is_ tested for in gdb.ada/info_auto_lang.exp, and its not clear to me
if the change is a good one or not, so for now I have left this out.

gdb: Improve output from "info types" commad

This commit makes two changes to the "info types" command:

First, only use typedef_print for printing typedefs, and use
type_print for printing non-typedef scalar (non-struct) types.  The
result of this is the output for builtin types goes from this:

    typedef double;
    typedef float;
    typedef int;

to this:

    double;
    float;
    int;

which seems to make more sense.

Next GDB no longer matches msymbols as possible type names.  When
looking for function symbols it makes sense to report matching
msymbols from the text sections, and for variables msymbols from the
data/bss sections, but when reporting types GDB would match msymbols
of type absolute.  But I don't see why these are likely to indicate
type names.  As such I've updated the msymbol matching lists in
symtab.c:search_symbols so that when searching in the TYPES_DOMAIN, we
never match any msymbols.

5 years agoMake documentation of "python" command match actual behavior
Kevin Buettner [Thu, 27 Jun 2019 02:38:24 +0000 (19:38 -0700)]
Make documentation of "python" command match actual behavior

The example in the documentation for the "python" command shows GDB
outputting instructions for how to terminate a sequence of python
commands entered from the command line.  The documentation shows that
the following two lines are being output, though this does not occur
when actually using the "python" command from GDB:

    Type python script
    End with a line saying just "end".

While display of this text might be helpful, GDB has several other
commands which also use the "end" terminator that offer no such text.
Examples include the "if" and "while" commands.  For example,

(gdb) if 1==1
 >print "a"
 >end
$1 = "a"

This seems similar to doing:

(gdb) python
 >print 23
 >end
23

If we decide that we want the "python" command to print such a message,
we should also adjust the behavior for other GDB commands which also use
"end" to terminate a command list.  I.e, if this decision is made, the
"if" and "while" commands ought to also print similar messages.

So, for the moment anyway, this commit adjusts the documentation of the
python command to match its implementation.

This patch was taken from a larger body of work originating from the
Archer project.  I haven't been able to determine its original author,
though I did find a commit log from Jan Kratochvil (in the Archer
repository) which suggests that the change had originally been made to
gdb.texinfo, but got inadvertently dropped when the python related
documentation was split out to python.texi.

gdb/riscv: Write 4-byte nop to dummy code region before inferior calls

When making inferior function calls GDB sets up a dummy code region on
the stack, and places a breakpoint within that region.  If the random
stack contents appear to be a compressed instruction then GDB  will
place a compressed breakpoint, which can cause problems if the target
doesn't support compressed instructions.

This commit prevents this issue by writing a 4-byte nop instruction to
the dummy region at the time the region is allocated.  With this nop
instruction in place, when we come to insert the breakpoint then an
uncompressed breakpoint will be used.

This is similar to other targets, for example mips.

5 years agoFix for using named pipes on Windows

Fix for using named pipes on Windows

On Windows, passing a named pipe as terminal argument to the new-ui
command does not work.

The problem is that the new_ui_command function in top.c opens the
same tty three times, for stdin, stdout and stderr.  With Windows
named pipes, the second and third calls to open fail.

Opening the file only once and passing the same stream for stdin,
stdout and stderr makes it work.

Pedro says:

 I tried it on GNU/Linux and things still work.
 I ran all the MI tests with forced new-ui, with:

 $ make check TESTS="gdb.mi/*.exp" RUNTESTFLAGS="FORCE_MI_SEPARATE_UI=1"
