src/ia32/disasm-ia32.cc:465: return 1;
what kind of warning do you get here? this return can never be reached
(cases end with return, and default captures everything else). seems
like a bug in the compiler.

ditto. what does compiler say? this can never be reached both branches
of the if statement end with returns.

and the same question again (default is present and all cases terminate
with returns).
