Compiling the attached .ll file with the following commands:
llc reduced.ll -mcpu=native -O2 -o reduced.s
as reduced.s -o reduced.o
gcc -o a.out reduced.o
./a.out
gives the output:
-81.000000 68.000000
The correct answer is:
-91.000000 58.000000
and is what is produced by the x86 backend.
It appears that the instruction %Z.L.JA291.9 is being erroneously omitted.</pre>
