You are inside a compiler, following a seemingly-endless sequence of
testsuite failures.

Behind you, you see 
gcc.sum gcc.c-torture/unsorted/cp.c,

Here, there is a 
gcc.sum gcc.c-torture/execute/920501-1.c

On the floor, there is a note.

> read note
The note reads:

What's happening is that:

x(){if(!s[0]){s[1+s[1]]=s[1];return 1;}}

flow2 tries to make this a conditional return, which would be OK
but for the way that it manages to delete the 'return 1' on the way;
it turns it into a (clobber (reg/i:SI 3 r3)).

You beat at the compiler.  It lets you move forward a little.
