runningundervalgrind.cpp

一套DDR OL 游戏源码.也就是所谓的SMO.内置SQL 及其完善的源码 可以用作2次开发等

#include "../crashDefines.h"
#include "RunningUnderValgrind.h"

#if defined(CPU_X86) && defined(__GNUC__)
bool RunningUnderValgrind()
{
	/* Valgrind crashes and burns on pthread_mutex_timedlock. */
        static int under_valgrind = -1;
	if( under_valgrind == -1 )
	{
		unsigned int magic[8] = { 0x00001001, 0, 0, 0, 0, 0, 0, 0 };
		asm(
			"mov %1, %%eax\n"
			"mov $0, %%edx\n"
			"rol $29, %%eax\n"
			"rol $3, %%eax\n"
			"ror $27, %%eax\n"
			"ror $5, %%eax\n"
			"rol $13, %%eax\n"
			"rol $19, %%eax\n"
			"mov %%edx, %0\t"
			: "=r" (under_valgrind): "r" (magic): "eax", "edx" );
	}
	
	return under_valgrind != 0;
}
#else
bool RunningUnderValgrind()
{
	return false;
}
