[issue23644] g++ module compile fails with ‘_Atomic’ does not name a type

2015-03-16 Thread Leonardo Bianconi

Leonardo Bianconi added the comment:

@haypo

For adding compatibility for atomics based on @Joshua.J.Cogliati change, I 
propose:

#ifndef Py_LIMITED_API
#ifndef Py_ATOMIC_H
#define Py_ATOMIC_H

#include "dynamic_annotations.h"

#include "pyconfig.h"

#if defined(HAVE_STD_ATOMIC)
#ifdef __cplusplus
#include 
#define _Atomic(T) atomic
using namespace std;
#else
#include 
#endif
#endif

#ifdef __cplusplus
extern "C" {
#endif


/* This is modeled after the atomics interface from C1x, according to
 * the draft at
 * http://www.open-std.org/JTC1/SC22/wg14/www/docs/n1425.pdf.
 * Operations and types are named the same except with a _Py_ prefix
 * and have the same semantics.
 *
 * Beware, the implementations here are deep magic.
 */

#if defined(HAVE_STD_ATOMIC)

typedef enum _Py_memory_order {
_Py_memory_order_relaxed = memory_order_relaxed,
_Py_memory_order_acquire = memory_order_acquire,
_Py_memory_order_release = memory_order_release,
_Py_memory_order_acq_rel = memory_order_acq_rel,
_Py_memory_order_seq_cst = memory_order_seq_cst
} _Py_memory_order;

typedef struct _Py_atomic_address {
_Atomic (void) *_value;
} _Py_atomic_address;

typedef struct _Py_atomic_int {
atomic_int _value;
} _Py_atomic_int;


... (rest same)

[issue23644] g++ module compile fails with ‘_Atomic’ does not name a type

2015-03-16 Thread Leonardo Bianconi

Leonardo Bianconi added the comment:

> #define _Atomic(T) std::atomic
Does not work, since there are definitions like "memory_order_relaxed" that are 
in std.

I tested the other one, and it works fine:
>#ifdef __cplusplus
>extern "C" {
>#if defined(HAVE_STD_ATOMIC)
>using namespace std;
>#endif
>#endif

@haypo, what do you think?
