Subject: Moving long long int using inline asm
Date: Thu, 01 Feb 2007 08:29:00 -0000	[thread overview]
Message-ID: <ba0bd44d0702010029haf80d65r9a0b2352a6b8e5e8@mail.gmail.com> (raw)

Hello all,

There are two variables
long long var1;
long long var2;

Using inline assembly how will i be able to move the value from var1 to var2,
i.e var2 = var1

The architecture has only a 32 bit move instruction say mov32
Something like

asm( "mov32 %0, %1"  : "=r"(var2) : "r"(var1) );

would have worked fine for 32bit data types.What is the similar syntax
for 64 bit data types?

Can someone help me?

Thanks in advance.

Regards,
Shafi
