[Issue 11902] DMD debuginfo doesn't seem to write classes correctly
https://d.puremagic.com/issues/show_bug.cgi?id=11902 --- Comment #8 from Manu turkey...@gmail.com 2014-01-22 01:44:34 PST --- (In reply to comment #7) I do agree that we're forced to live with any bugs in VS. Even if Microsoft fixes them, those fixes often don't wind up on users' machines. If @ is the only thing that will work across the VS versions, I'll pull Rainer's patch for it. I just think it's painfully ugly. Does it make sense to activate it on a compile flag, then VD can supply it when it needs to? If there are differences between the 2 debug engines, then it makes sense to support the newer debug engine one by default, and the old one on a compile flag, especially since VS2008-2010 are still in very common use. I'm sure Rainer knows the most appropriate way to handle these problems. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

As soon as this is done and its fully working, I would think that mago will be the primary choice to debug D on Windows within Visual Studio, as it supports D specific debugging features (e.g. evaluating D expressions). And as soon as mago becomes the defacto standard for debugging the @ mangling is no longer needed. So adding a switch as temporary solution might be the best choice. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

https://d.puremagic.com/issues/show_bug.cgi?id=11962 --- Comment #4 from Manu turkey...@gmail.com 2014-01-22 03:09:20 PST --- Sure, they're both related to the CRT to linkage. I think you're reading too much into the second sentence of my OP. The 'cause' of this bug specifically is that VisualD doesn't present an option in the project settings. That's unrelated to DMD's choice of default, although sure, the reason I was motivated to look for the option was that I wanted to change it for debug builds, though there are many other cases where you want to choose a different CRT too. The full suite of CRT's should be available to choose from. Linking against various libraries demand that you choose different libs, and there are also times where you'd rather link to the DLL than statically. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

The following code used to work with 2.064.2:
inout(char)[] stripped (inout(char)[] path)
{
return path;
}
struct PathParser
{
inout(const(char))[] pop () inout
{
return stripped (path);
}
inout(const(char))[] path () inout
{
return null;
}
}
void main ()
{
auto a = PathParser().pop;
}
With 2.065.b1 it results in this error:
Error: function main.stripped (inout(char)[] path) is not callable using

Reduced example:

}
The code `i = i;` does nothing, but there are no compiler error.
This error in real life:

When compiling this code with dmd -O it says:
test.d(55) Error: variable r used before set
i might have overlooked something, but shouldn't that compile?
I tried to test on Windows.
I suppose this is an _expected_ behavior.
Maybe, 'r.ptr[4]' and its followings lines should be 'r.ptr[0]' and so on.
Please help, SIMD expert... :)

Reduced Code:
//DMDFLAGS=-O -m64
import core.simd;
alias float[8] F8;
F8 simdAdd(F8 a1, F8 a2) {
F8 res;
float4 v1;
float4 v2;
float4 r;
// 0..4 OK
v1.array = a1[0..4];
v2.array = a2[0..4];
r = __simd(XMM.ADDPS, v1,v2);
res.ptr[0] = r.ptr[0];
res.ptr[1] = r.ptr[1];
res.ptr[2] = r.ptr[2];
res.ptr[3] = r.ptr[3];
// 4..8 NG
v1.array = a1[4..8];
v2.array = a2[4..8];

--- Comment #9 from daniel...@bigpond.com 2014-01-22 21:33:11 PST ---
I've just given up on this idiom, instead using:
```
import std.algorithm;
import std.stdio;
void main() {
auto items = [10, 20, 30];
auto t = items.filter!(x = x != 20).copy(items);
items = items[0 .. $ - t.length];
writeln(items);
}
```
Its the only option that has clear time and space semantics.

[Issue 11946] need 'this' to access member when passing field to template parameter

--- Comment #6 from Kenji Hara k.hara...@gmail.com 2014-01-22 21:52:01 PST ---
I change my argue to that this regression should be marked as invalid.
(In reply to comment #5)
(In reply to comment #0)
static // http://d.puremagic.com/issues/show_bug.cgi?id=7805
int f(A...)() { return 0; }
struct S { int x; enum y = f!x(); }
This should never have compiled. static should never have affected a template
in global scope.
I also think so. But it had been worked because 'static' attribute is always
inherited to the instantiated function. I *fixed* the bug in the PR:
This used to compile, but it was broken by
https://github.com/D-Programming-Language/dmd/pull/2794
===
The main point of enhancment 11533 is that 'static template' should always
behave as same as module-level templates, regardless its declared position.
It's increasing consistency with currently known language concepts:
- 'static' attribute on module level declaration is just redundant
(meaningless).
- 'static' declaration inside aggregates/functions should behave as same as
module level declarations.
* static member function is equivalent with free functions.
* static local function is equivalent with free functions.
By the fix, `static int f(A...)(){ ... }` and `int f(A...)(){ ... }` have now
no difference at module level.
Therefore, instantiated f!(S.x) always requires hidden 'this' pointer on the
call.
To be more precise, current D language alias template parameter is not designed
just to take a symbol that is needed just only at compile-time.
If given template argument has implicit runtime context, compiler will _always_
try to take runtime context at the same time.
(To resolve the issue, nested-ness interence is sometimes proposed. But I'm
still not sure it is possible feature.)
To ignore the implicit automatic capturing, you need to write the idiom I
explained in comment#1.
As a conclusion: the reported breaking change is necessary due to add more
consistency to the language spec.

Following code leads to segmentation fault:
void main()
{
foo!double Foo ;
Foo.zoo(1.0);
}
You're call instance method 'zoo' on null object reference.
void main()
{
foo!double Foo;
assert(Foo is null); // !
Foo.zoo(1.0); // Segfault
}
To me the segfault looks intended result.

https://d.puremagic.com/issues/show_bug.cgi?id=11946
--- Comment #7 from Vladimir Panteleev thecybersha...@gmail.com 2014-01-23

It's increasing consistency with currently known language concepts:
Yes, this is all fine and well, but it does not justify making code that worked
before now break with an indecipherable error message! The message need 'this'
to access member f is an outright lie and is only good at showing a glaring
compiler implementation problem.
(In reply to comment #1)
template f(alias X)
{
static string f()
{
//int x = X;
return X.stringof; // OK
}
}
This just shows another bug - that you still need static (which makes NO
sense for a free function, templated or not), but now you must hide it inside a
template!
To be more precise, current D language alias template parameter is not
designed
just to take a symbol that is needed just only at compile-time.
If given template argument has implicit runtime context, compiler will
_always_
try to take runtime context at the same time.
So fix this first before breaking code?
To ignore the implicit automatic capturing, you need to write the idiom I
explained in comment#1.
If one needs to go to a bugtracker and learn of a hacky workaround (put a
static function in a template) from a compiler developer to make their code
compile, this is a terrible situation for D.
As a conclusion: the reported breaking change is necessary due to add more
consistency to the language spec.
I suggest that consistency bugs are fixed only after there is an immediate and
obvious way to transition code that should not have compiled, to correct code
which functions in the same way. In either case, this bug remains a REGRESSION.

[Issue 10959] std.algorithm.remove is highly bug-prone
https://d.puremagic.com/issues/show_bug.cgi?id=10959
--- Comment #10 from monarchdo...@gmail.com 2014-01-22 23:22:14 PST ---
(In reply to comment #9)
I've just given up on this idiom, instead using:
```
import std.algorithm;
import std.stdio;
void main() {
auto items = [10, 20, 30];
auto t = items.filter!(x = x != 20).copy(items);
items = items[0 .. $ - t.length];
writeln(items);
}
```
Its the only option that has clear time and space semantics.
Ref: http://dpaste.dzfl.pl/84273326
How is that any different from:
items = items.remove!(x = x == 20)()
?

Yes, this is all fine and well, but it does not justify making code that
worked
before now break with an indecipherable error message! The message need
'this'
to access member f is an outright lie and is only good at showing a glaring
compiler implementation problem.
There's no lie. The instantiated function _always_ needs valid runtime context,
*regardless* the context is really used or not inside function body.
Unfortunately current D has _no_ language feature to remove unused context
pointer (I call it nested-ness inference).
(In reply to comment #1)
template f(alias X)
{
static string f()
{
//int x = X;
return X.stringof; // OK
}
}
This just shows another bug - that you still need static (which makes NO
sense for a free function, templated or not), but now you must hide it inside
a
template!
It's not a bug. If the symbol X needs runtime context ('this' object or
function frame), f() will be instantiated like as member function or nested
function. To remove the implicit context pointer, 'static' will work.
---
After fixing issue 11533, these two declarations have different meanings.
template f(alias X) { static string f() { return null; } } // A
static template f(alias X) { string f() { return null; } } // B
In A, 'static' attribute is always added to the instantiated function 'f'. So
Even if X requires runtime context, 'f' still cannot access it.
In B, 'static' attribute is added _if_ X has no runtime context. If X needs
runtime context, instantiated 'f' also take the context to access valid runtime
storage of X.

I already explained the way to do it in comment#1.

There's no lie. The instantiated function _always_ needs valid runtime
context,
*regardless* the context is really used or not inside function body.
What?!?!?
This makes absolutely no sense!
There is nothing in the D spec about this! Templated functions must behave in
the same way as free functions (whether the function itself is templated or it
is inside an explicit template declaration), and static is meaningless on
free functions!
We are not talking about template mixins! The instantiation of non-mixin
templates uses the template declaration's context!
Unfortunately current D has _no_ language feature to remove unused context
pointer (I call it nested-ness inference).
As far as I can see, this is just a compiler implementation detail!
Can you provide an example where this feature (passing context pointer from
template instantiation site to a free function) is actually used?
It's not a bug. If the symbol X needs runtime context ('this' object or
function frame),
It doesn't! .stringof does not need a gosh-darn context pointer!
f() will be instantiated like as member function or nested
function.
WHY?!?
It is a free function!
To remove the implicit context pointer, 'static' will work.
...
After fixing issue 11533, these two declarations have different meanings.
template f(alias X) { static string f() { return null; } } // A
static template f(alias X) { string f() { return null; } } // B
In A, 'static' attribute is always added to the instantiated function 'f'. So
Even if X requires runtime context, 'f' still cannot access it.
In B, 'static' attribute is added _if_ X has no runtime context. If X needs
runtime context, instantiated 'f' also take the context to access valid
runtime
storage of X.
This looks like absurd overcomplication. Do you really expect D users to have
to understand the difference?
It would be a not trivial language enhancement that still not yet designed.
Then I suggest that you postpone all breaking changes until all that is figured
out. Breaking code to clean up compiler internals is inexcusable, IMO!
To explain the behavior, I'll update webside documentation and add a section
in
release note.
The more I think about it the less sense it makes to me. Maybe it makes sense
from the point of view of a compiler developer (to use Chen Raymond's
phraseology, you're looking at the world through compiler-tinted glasses).
But as a D user, your explanation reads like one giant WTF to me. It is
completely unintuitive and to me it seems that things are broken at a much more
fundamental level if you defend the current logic in this way.
