reduced testcase
I have seen plenty of wrong code cases with -enable-mssa-loop-dependency the
last two weeks (in testing), and have now reduced one program.
gcc -O0 -march=z10 -o a.out
gcc -O1 -march=z10 -o a.out
gcc -O0 -march=z13 -o a.out
gcc -O1 -march=z13 -o a.out
clang -O0 -march=z10 -o a.out
clang -O0 -march=z13 -o a.out
clang -O3 -march=z10 -o a.out
clang -O3 -march=z13 -o a.out
The above programs all print "5", but this one prints "0":
clang -O3 -march=z13 -o a.out -mllvm -enable-mssa-loop-dependency
