IA64 Windows weird asm issue

[Sergey Kashyrin]

Gentlemen,

Did anybody face the following problem ?
I've did ia64 windows build, and all tests passed okay (with the exception of locale.exe which I don't care about).
The result was not that good as expected - at least it slower than on my athlon64, and other tasks usually about 3 times faster on 
IA.
So I've tried to use assembly code.

The result is:
If I put "copyi.asm" in, couple of tests are failing (see below).
If I don't put asm copyi, copyb and invert_limb than tests are okay, but they are running approximately 15 times slower (!!!), i.e. 
almost 3 minutes instead of 10 seconds.

What can be wrong ?
 (all generated & compiled using intel iasm for little-endian. add_n and sub_n were need to be compiled with "explicit", otherwise 
they were producing the errors)

Regards,
Sergey
