If we change the asm to like so:
asm(""
: "+r" (a), "+r" (b), "+m" (blen), "+m" (out), "=&r" (tmp)
: "m" (d)
: "eax", "edx");
We don't get an error.
Also using -fomit-frame-pointer works around the problem by adding another free
register.
What is most likely happening is we are not selecting the secondary constraint.
Oh, reload sucks.
