There is an API mismatch between the 32-bit and 64-bit core.stdarg, which should be fixed (I'd suggest making core.stdarg simply forward to core.stdc.stdarg, which is correct).

This is a reduced case (Loss of error flag) for a more common bug:

int foo(bool cant_be_true) {
int error = cant_be_true ? -1 : 1;
return error;
}
void main() {
uint x = foo(true);

This is a real bug in good C++ code:
if ((p_newHeader.frame_num != m_lastSlice.frame_num) ||
(p_newHeader.pic_parameter_set_id !=
p_newHeader.pic_parameter_set_id) ||
(p_newHeader.field_pic_flag != p_newHeader.field_pic_flag) ||
(p_newHeader.bottom_field_flag != m_lastSlice.bottom_field_flag)
){
return false;
}
The bug is of the kind:
if (x != x) {}
Two other similar bugs:
if (x == x) {}
auto y = x - x;
For the compiler it's easy to spot such three situations. They are correct
code, yet experience shows that often such redundancies hide bugs. So I suggest
to add to DMD warnings for such tree situations.

This is D2 code:

Foo* bar() {
Foo f = Foo(1);
return &f;
}
void main() {}
DMD 2.051 raises a compile-time error:
test.d(6): Error: escaping reference to local f
But this code compiles and runs with no errors with DMD 2.051. I think DMD has
to statically disallow code like this too:

int x;
}
Foo* bar() {
return &(Foo(1));
}

This is Python 2.6.6 code (shell):

'1x2x3'
This is handy in several situations. So I'd like std.string.join() to join
chars in a similar way:

In DMD 2.051 to!int acts as cast(int) on chars:

void main() {
assert(to!int("1") == 1);
assert(cast(int)'1' == 49);
assert(to!int('1') == 49);

But I think this is more handy:

This is Python 2.6.6 code (shell):
>>> items = [1, 7, 22]
>>> all(x % 2 for x in items)
False
>>> items = [1, 7, 21]
>>> all(x % 2 for x in items)
True
The functions all() and any() are very handy.
With Phobos of DMD 2.051 if you want to translate that Python code to a D2
functional style you need something like:
import std.algorithm;
void main() {
auto items = [1, 7, 22];
bool r1 = reduce!q{a && b}(true, map!q{a % 2}(items));
assert(!r1);
items = [1, 7, 21];
bool r2 = reduce!q{a && b}(true, map!q{a % 2}(items));
assert(r2);
}
While using an all() it becomes shorter and more readable, something like
(untested):
import std.algorithm;
void main() {
auto items = [1, 7, 22];
bool r1 = all!q{a % 2}(items);
assert(!r1);
items = [1, 7, 21];
bool r2 = all!q{a % 2}(items);
assert(r2);
}

I have written a duplicated enhancement request: bug 5544
There I have asked an all() and any() that allow to write code as this:

void main() {

bool r1 = all!q{a % 2}(items);
assert(!r1);
items = [1, 7, 21];
bool r2 = all!q{a % 2}(items);
assert(r2);
}
Instead of:
import std.algorithm;
void main() {

bool r1 = reduce!q{a && b}(true, map!q{a % 2}(items));

I apologize for the length of this test case, it was reduced from a ~1500 line
file with a failing unittest. The following bug seems to be caused by DMD
failing to increment i in the struct Perm. It only happens under -O -release
-m64. Omitting any of these flags makes this program work. Also, the call to
enforce() is necessary to reproduce the bug.
import std.stdio;
bool enforce(bool value, lazy const(char)[] msg = null) {
if(!value) {
return false;
}
return value;
}
struct Perm {
byte[3] perm;
ubyte i;
this(byte[] input) {
foreach(elem; input) {
enforce(i < 3);
perm[i++] = elem;
stderr.writeln(i); // Never gets incremented. Stays at 0.
}
}
}
void main() {
byte[] stuff = [0, 1, 2];
auto perm2 = Perm(stuff);
writeln(perm2.perm); // Prints [2, 0, 0]
assert(perm2.perm[] == [0, 1, 2]);
}

[Issue 5546] New: Assigning and initializing structs from functions make more copies than necessary
http://d.puremagic.com/issues/show_bug.cgi?id=5546 Summary: Assigning and initializing structs from functions make more copies than necessary Product: D Version: D2 Platform: x86_64 OS/Version: Linux Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: akb...@gmail.com --- Comment #0 from akb...@gmail.com 2011-02-07 23:31:56 PST --- When initializing a struct from a function that returns by value, more copies (calling the post blit and destructors) are called than are necessary. For example, see the attached source file. The output for TestCopy.d is currently: Creating temp Copying temp Deleting temp Creating copy Copying copy Deleting copy Forwarding copy Copying copy Deleting copy Returning global Copying global Deleting global Deleting copy Deleting temp Ideally, the output should look like this: Creating temp Creating copy Forwarding copy Returning global Copying global Deleting global Deleting copy Deleting temp When a struct is being initialized by the return value of a function, apart from the memory being blitted over, no post blit or destructor should need to be called, since semantically it's equivalent to directly initializing the struct in the called function. This can be achieved by always returning a local object and not destructing the local object being returned. In the case of globalFunc(), which is returning a non-local object, a temporary would be made before returning from globalFunc(). When assigning the returning value of a function to a struct that's already initialized, additional optimizations can be made if no custom assignment operator exists. For example: Test testVal; testVal = function(); This will create the copy for the return value of function(), post blit testVal, destroy the previous value of testVal, then destroy the return value of function(). If Test or any of its members have an overridden assignment operator, they must be called. However, in the case where there is no custom assignment operator, the post blit of testVal and destruction of the return value of function() can be omitted, since you are semantically moving the value from the return value to testVal. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
