C++ Inline ASM code to get clock frequency for ARM - c++

Question

I was trying to compile ODE(Open Dynamics Engine) physics C++ library for Android Native application on Android Studio.
When i tried to build it, it gave me some error telling that some inline ASM code is not correct as they are written for INTEL processor syntax. This are mostly to get CPU clock frequency for physics simulation purpose.
(Editor's note: this x86 GNU C inline asm is inefficient and not even safe or portable. See How to get the CPU cycle count in x86_64 from C++? for correct ways to use i386 / x86-64 rdtsc.)
static inline void getClockCount (unsigned long cc[2])
{
#ifndef X86_64_SYSTEM
asm volatile (
"rdtsc\n"
"movl %%eax,(%%esi)\n"
"movl %%edx,4(%%esi)\n"
: : "S" (cc) : "%eax","%edx","cc","memory");
#else
asm volatile (
"rdtsc\n"
"movl %%eax,(%%rsi)\n"
"movl %%edx,4(%%rsi)\n"
: : "S" (cc) : "%eax","%edx","cc","memory");
#endif
}
static inline void serialize()
{
#ifndef X86_64_SYSTEM
asm volatile (
"mov $0,%%eax\n"
"push %%ebx\n"
"cpuid\n"
"pop %%ebx\n"
: : : "%eax","%ecx","%edx","cc","memory");
#else
asm volatile (
"mov $0,%%rax\n"
"push %%rbx\n"
"cpuid\n"
"pop %%rbx\n"
: : : "%rax","%rcx","%rdx","cc","memory");
#endif
}
static inline double loadClockCount (unsigned long a[2])
{
double ret;
#ifndef X86_64_SYSTEM
asm volatile ("fildll %1; fstpl %0" : "=m" (ret) : "m" (a[0]) :
"cc","memory");
#else
asm volatile ("fildll %1; fstpl %0" : "=m" (ret) : "m" (a[0]) :
"cc","memory");
#endif
return ret;
}
I don't know how to do same for ARM? Any help?
