GNU "cpp -P" portability

0 votes
422 views

Is "cpp -P" POSIX? I poked around at

http://www.opengroup.org/onlinepubs/**********

and could find only matches to "preprocessor" rather than "cpp" in the search facility, and so surmise "no", but thought i'd ask here anyway. I suppose a portable workaround would be:

cpp FILENAME | sed '/^#/d'

but have fingers crossed nonetheless...

No, it's much the same as gcc -P, as far as I could tell by looking it up.

GNU attributes with C++11 syntax?

GCC gives a warning for this program:

int main()
{
    int x;
}

test.cpp: In function 'int main()':
test.cpp:3:9: warning: unused variable 'x' [-Wunused-variable]

If I add an "unused" attribute with the GNU syntax:

int x __attribute__((unused));

the warning goes away.

However, if I use the C++11 syntax:

int x [[unused]];

the warning remains, and I also get:

test.cpp:3:20: warning: 'unused' attribute directive ignored [-Wattributes]

Does anyone know about gcc plans to support the attributes with C++11 syntax.

Extending the core language via a gcc plugin possible?

is it possible to add a private extension to the core language (C/C++) by writing a gcc plugin?

The extension in mind is something like this

[variable_definitions;]

Later I want this be possible also inside statement headers, for example

for ([double d = 1.0; bool f = false;] size_t i = 0; i < vec.size(); ++i)
 ...

The scope of the so-defined variables shall be the same scope they are in, ie. in the for-loop case just the scope of the for-loop itself, much like the case with i.

Why GCC prefers global size-unaware deallocation function?

I have the following operator delete replacements:

void operator delete[](void* p)
{
 /* Implementation does not matter. */
}

void operator delete[](void* p, std::size_t size)
{
 /* Implementation does not matter. */
}

My question is why, in the following code, GCC 6.2 calls void operator delete[](void*) and not the second replacement:

char* str = new char[14];
delete[] str;

According to 5.3.5 Delete [expr.delete]:
(10.3) If the type is complete and if, for the second alternative (delete array) only, the operand is a pointer to a class type with a non-trivial destructor or a (possibly multi-dimensional) array thereof, the function with a parameter of type std::size_t is selected.

Therefore, I believe operator delete[](void*, std::size_t) must be called, doesn't it?

What is the GCC C++ equivalent implementation of Windows _ MyFirst and _MyLast vector pointers?

I wanted to ask what is the GCC C++ equivalent implementation of Windows _ MyFirst and _MyLast vector pointers?

These give direct access to the vectors first and last element, but they are not present in the GCC implementation of the vector class.

Warning for incompatible functions declared 'extern "C"'?

I have an oversight in my code where I'm declaring & defining a function
with C-linkage, though it's not possible.

Example snippet:

#ifdef __cplusplus
extern "C"
{
#endif

// ... some functions which are compatible with C linkage

// Intended to be a helper function not exposed from library
std::string GetEngineVersion()
{
 // ...
}

#ifdef __cplusplus
}
#endif

Obviously the GetEngineVersion function cannot have C linkage because it returns a C++ class.

My question is: does GCC have a warning for this scenario? Specifically, can it warn when something is declared extern "C" that's incompatible with C linkage?

I compile with the following warning flags and I didn't get a warning:

-Wall -Wunused-parameter -Wextra -Weffc++ -Wctor-dtor-privacy
-Wnon-virtual-dtor -Wreorder -Wold-style-cast -Woverloaded-virtual
-Werror

Incidentally, when I compile the same code in VS2013 I get this warning:

warning C4190: 'GetEngineVersion' has C-linkage specified, but returns UDT 'std::basic_string' which is incompatible with C
...
