This is an FSF concern, it has to be sorted to their satisfaction and rules.

Patches to the GCC manual (to be found in the texinfo files in the
gcc/doc subdirectory of the sources).

> 4,5,6,7,8,10 - thanks for help, I made some corrections and improvements - wrote comments, tidy up the style, add more range and null-pointer checks. Also, as you suggested, in addition to "svc" I've implemented "smc" attribute and dummy "hvc" attribute - can't find documentation for hvc, I've just noted it's Hypervisor Call. Then code will be completed, I'll made patch for trunk, for now I can't checkout it, sorry.
