  The whole testsuite/gpc.pascal is almost empty,
I never invested time to develop it :(

  At the time I started it, GPC (the GNU pascal compiler)
was still active, but development apparently
stopped since quite some time.

  I am unable to install GPC, which means that I cannot test it.
Would a testsuite that supports only Free Pascal be acceptable?

Do you actually mean, whether it's ok for a new
test (not test suite) to go in untested on GPC?  It certainly is.
Better test on FPC than nowhere.  :-)

AFAICS, the tests themselves don't really care which compiler
is in use other than for marking xfails; you just call gdb_compile_pascal,
and that works with either.  That's my impression from quickly
skimming testsuite/lib/pascal.exp.

  The problem is that GPC and Free Pascal support several
pascal 'dialects'. But this requires command line options.

  The -Mobjfpc option is required for Free Pascal compiler
to understand class type definition, but is rejected in default mode.

  I expect GNU GPC to also reject class in 'normal' mode...
Maybe someone on the gpc mailing list knows if classes are supported
by GPC and if it requires a special compiler option.

Pierre Muller

FYI: Here is the example code that is included in the bug report.

$ cat ~/pas/test/test-class-pascal.pas

type
  TA = class
  public
  x, y : integer;
  constructor Create;
  function check(b : TA) : boolean;
  destructor Done; virtual;
end;

constructor TA.Create;
begin
  x:=-1;
  y:=-1;
end;

destructor TA.Done;
begin
end;

function TA.check (b : TA) : boolean;
begin
  check:=(x < b.x);
end;



var
  a, b : TA;

begin
  a:=TA.Create;
  b:=TA.Create;
  a.x := 67;
  a.y := 33;
  a.check (b);
end.

I'd suggest adding support for a new option to
gdb_compile_pascal, like "objfpc", so you'd compile
the test with:

 if {[gdb_compile_pascal ... executable [list debug objfpc]] != "" } {
     untested $testfile.exp
     return -1
 }

You'd teach fpc_compile about the new option:

proc fpc_compile {source dest type options} {
...
    foreach i $options {
...
        } elseif { $i == "objfpc" } {
           append add_flags " -Mobjfpc"
        }
...
    }


Someone that cares about testing with GNU GPC would then
do the equivalent to gpc_compile, if anything is necessary.
If gpc simply fails to compile the test, it's no biggie,
as gdb_compile_pascal returns false, and the test is
skipped with "untested".

There may be a more generic and common name for the mode,
like "obj-pascal" or something, but I wouldn't know.

Pedro Alves

To clarify, I meant, it is my impression that objfpc is a
dialect of Object Pascal:

[RFA PATCH 1/3] Remember the case pattern that allowed finding a field of this.

[Pierre Muller]

  In the pascal parser, there is special code
that will try to emulate case-insensivity despite the
fact that pascal is not registered as a 'case-insensitive' language.

  This code does not work as expected for fields of a class,
for which exact casing is currently required.
  The patch below fixes this problem.

[RFA 0/3] Fix pascal behavior for class fields with testcase

[Pierre Muller]

 I finally started to try git format-patch.

  The three patch emails that will follow contain:

1) The fix in p-exp.y to cope correctly with this fields

2) New options for pascal compilation in the testsuite

3) A testcase for PR pascal/17815

I hope this is correct...
but there are surely some formatting and
name conventions that I do not follow correctly...

Hi.
This patch makes me uncomfortable.
It's to a pascal specific file, so at least the discomfort is contained :-),
but I wouldn't want this spreading.

How to select debug information should be
orthogonal to compilation language,
and there are a myriad of ways to select what kind of dwarf debug info
to get (with/without type units, with/without .gdb_index, with/without
dwz, and so on).  I have board files to help me drive the various
combinations I'm interested in.  This won't work if gdb.pascal/*
starts hardcoding debug info into the test.

Maybe there's a good reason to do it this way for pascal,
but I need more data.

 Hi Doug, the reasons of this patch are:

1) the particular problem that the series fixes is strictly limited
to stabs debugging information.

  Thus to really test that this bug has been fixed, I need to compile
the test code using stabs debugging format (which I now realize
I did not do in the third part of the patch series).

2) the pascal language support tries to support both
GNU pascal compiler (aka GPC) and Free Pascal Compiler (aka FPC).

  These two compilers have very different options,
so the submitted patch purpose is to unify the selection of stabs versus dwarf
debug format independently from the used pascal compiler.

 For other pascal tests, only debug is used, which results in the default
format according to the target architecture and operating system.

I hope that the explanations above are sufficient to ease your discomfort.

Yeah, I figured those are the reasons, but I dunno.
We're inventing something new here when existing mechanisms
can already handle this.

One *could* have the test be debug-format agnostic,
and to test with stabs just do
make check RUNTESTFLAGS=--target_board=stabs

If you're using stabs you'll want to run the whole testsuite with stabs anyway.

Plus if a compiler has a different spelling for -gstabs, one could
have another board file for that compiler: you'll want to run the
whole testsuite
with that compiler anyway.

make check RUNTESTFLAGS="gdb.pascal/*.exp --target_board=fpc-stabs"

or some such.

Obviously, by "whole testsuite" I mean the pascal parts.
So that raises a question that may help guide the discussion.
When testing with fpc, how do you run the testsuite?
Do you just run the pascal subset, gdb.pascal/*.exp?
Or do you run the WHOLE testsuite (i.e., gdb.*/*.exp),
e.g., just a plain "make check"
and expect the test harness to pick up fpc and DTRT.
How do other languages handle this I wonder.

I'm not totally opposed to this (I don't like to say "No."),
but I'm still uncomfortable with the patch.

  OK, 

so let's do it that way:
I removed the part you are uncomfortable with
and simplify the part 2 to only add the new "class" option,
see updated patch below.

  I can always resubmit this later
if I really feel that it is useful,
but I admit that your point about the default 
debug mode is valid.

  Is the modified patch series
OK for you?

Missing '*'.

Can you please pick a more descriptive name for the file?
One that suggests what's being tested, rather than a bug
number is ideal.  E.g., gdb.pascal/case-insensitive.{exp|pas}.

I won't object to this, given that it seems like all
pascal tests do it, but I'll note that it's best to avoid
gdb_start_cmd unless we're really testing the "start" command,
as otherwise the test won't run against gdbserver
(try --target_board=native-gdbserver).  Doesn't runto_main
work?

Could you add a period at end of sentences?  Here and throughout.

Should be "its".

Or, "check its value"?  What's a _global_ value?

It'd be good to try setting this in a board file to make sure it
works.  I've spotted a typo here (same in the gpc branch): "pscal_class_flags".

  I corrected the error below,
but I never worked with boardinfo files,
so I am not really sure how this works.

  No, I tried and using runto_main,
I got only failures, because it apparently did not stop
at all on the breakpoint set earlier...
Is there some code inside runto_main that
deleted previously installed breakpoints?
Why is that so?
  I kept gdb_start_cmd for now.

[RFA PATCH 1/3 V3] Remember the case pattern that allowed finding a field of this.

[Pierre Muller]

For this one also,
an update is necessary:
I realized that I got wrong output
for some field of this variables,
and it turned out to be due to missing
initialization of some local variables.

Should be something around this:

Create an empty ~/etc/site.exp file.  Point the
DEJAGNU environment variable to it, like:

  export DEJAGNU=/home/pedro/etc/site.exp

Create a ~/etc/boards/ directory, and create
a ~/etc/boards/fpc.exp file with this:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
unset_board_info isremote
set_board_info isremote 0
load_generic_config "unix"

set_board_info compiler "[find_gcc]"

set_board_info pascal_class_flags "-Mobjfpc"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Run the pascal tests with

make check RUNTESTFLAGS="--target_board=fpc --directory=gdb.pascal"

Play with $pascal_class_flags, and make sure it does have the
effect intended.

The patch looks good to me.

Thanks,
Pedro Alves

You mean, it's just for symbols, rather than filesystems, etc?
gdb.pascal/case-insensitive-symbols.{exp|pas} would be my
suggestion then.  But these are just suggestions.  Feel free to
pick something else.

Yes, it's the first thing runto_main -> runto does.

Why not just set the breakpoints after reaching main?

Or simpler still, use "runto $foo" directly, like:

set bp_location [gdb_get_line_number "set breakpoint here"]
if { ![runto ${srcfile}:${bp_location}] } {
    return 0
}

Or simpler still, just:

if { ![runto "check"] } {
    return 0
}

Assuming that to set a breakpoint on the "check" function,
you'd do "break check" in GDB.  If not, replace "check" with
whatever linespec would be used instead.

The patch looks good to me.

Thanks,
Pedro Alves

[RFA PATCH 1/3 V4] Remember the case pattern that allowed finding a field of this.

[Pierre Muller]

  This is the fix in the pascal parser (p-exp.y),
to avoid the error that GDB does find normal variables
case insensitively, but not fields of this,
inside a class or object method.

[RFA 0/3 V4] Fix pascal behavior for class fields with testcase

[Pierre Muller]

  Hi all,

this is a new round of my patch series to 
treat fields of this like any other variable
in the pascal parser.


  Pierre Muller
as pascal language maintainer.

PS: I got problem to test my series because I get an
internal-error with stabs generated debug information:

Doug, I suspect this is due to the series you committed

No calls to set_type_self_type up to this error point.

TOBJECT is the fundamental class type for Free Pascal,
and this code had no problems before.

[RFA PATCH 2/3 V4] Add "class" option for pascal compiler

[Pierre Muller]

This part of the patch series is unchanged.
It adds class option to pascal compiler
which adds the required command line option to
accept pascal class types.
