[llvm-dev] TryToShrinkGlobalToBoolean in GlobalOpt.cpp issue

[Ryan Taylor via llvm-dev]

Given some code:

static int x = 100;

int main() {
   x = 101;
   printf("%d\n", x);
}

results in:

%0 = load i1
%1 = select %0, 101, 100
...
...

1) What architecture(s) does this benefit?
2) What's the best way to circumvent this in the backend (currently I am
just not allowing this opt function to run)? I have tried a few
setOperationAction methods to no result. Rather not just comment out core
code because it makes porting more difficult.
