Hi.....

I am facing some problem with using VCVT arm(cortex A8) instruction in c++ source file.

In some article, they mentioned like , The inline assembler does not provide direct support for VFP instructions like VCVT etc. So we need to use some equate assembly instructions.
I have tried with some equate instrcutions like FTOSI instruction also.It is not working.

I tried like,
__asm
{
   VCVT.S32.F32 source, destination
}

kindly help me if u peoples have any idea and give me some examples that how to use this instruction in c++ file?

I need to use CORTEX-A8 assembly instruction which is converting from floating point to integer in c++ source file.
