I'm now porting omniORB3(an ORB from AT&T) to RTLINUX.
I met an error from g++ after I included rtl_cpp.h to this project.
I think that this version of g++(2.95.3) cann't compile inline assembler code in the
appropriate way.
I captured the executing screen as follows.

=============================================================
Inline assembly code which arises an error is as follows.
Tell me how can I make this g++ recognize this C++ code.
============================================================
extern inline void __set_64bit (unsigned long long * ptr,
unsigned int low, unsigned int high)
{
__asm__ __volatile__ (
"1: movl (%0), %%eax;
movl 4(%0), %%edx;
cmpxchg8b (%0);
jnz 1b"
:: "D"(ptr),
"b"(low),
"c"(high)
:
"ax","dx","memory");
}
===========================================================
Thank you
