Falk, sorry but Andrew is right. 
 
First of all, it *does* compile for me at -O[123] on i686, but not  
at -O0 because reload can't find a register.  I tried GCC 3.3, 3.4, 
and 4.0, and -march={i386,i686,athlon-xp,pentium4}, and all these 
versions behave the same. 
 
Second, both PRs concern a basically overly constrained asm.  I am 
sure I mentioned in PR11203 that any success in compiling such asm 
is just luck. 
 
Not a GCC bug
