This is an assembler error for a .S file, which means it has nothing to 
do with gcc.  It is either a newlib bug or a binutils bug.  Probably a 
newlib bug.  Looks like newlib doesn't support thumb2.

By the way, we don't track bugs mailed to the gcc-bugs mailing list. 
GCC bugs should be filed into bugzilla, or ask a question on the 
gcc-help mailing list.
