assembly


what's the embeded assemble instruction to get floating point exponent on x64 and mips linux platform and how to use it


recently i read a book called CSBU(Computer Science from the Bottom Up), and there is one assemble instruction used to directly get the floating point exponent, related code snippet:
long double d = 0x8000UL;
long exp;
// Itanium "get floating point exponent" instruction on Itanium platform
asm ("getf.exp %0=%1" : "=r"(exp) : "f"(d));
So, anyone who can tell me which exactly instruction takes the same effect on x64 and mips platform and how to use it.
many thanks!
