Apparently so as illustrated by:

http://gcc.gnu.org/ml/gcc-patches/2007-10/msg00488.html

It seems that I have broken backward compatibility.  If the user uses '{' 
and '}' in bitfield instructions, then his/her code won't assemble.

gcc's asm statements require the user to be familiar with gcc's internal to 
some extent, but I am not sure if we want to expose directives for assembly 
diarect.

Thoughts?
