+// issue-0006: literal `0` in integer comparison inferred as float inside f32 ternary
+//
+// When `s64 != 0` is used as the condition of a ternary whose result type is f32,
+// the literal `0` in the comparison leaks the ternary's f32 type instead of matching
+// the LHS s64 type. This generates invalid LLVM IR:
+//   %icmp = icmp ne i64 %load, float 0.000000e+00
+//
+// The same comparison works fine in a regular if-statement.

+#import "modules/std.sx";

+    x : s64 = 42;

+    // OK: comparison in statement context
+    if x != 0 { out("ok\n"); }

+    // BUG: comparison as condition of f32 ternary — `0` inferred as f32
+    result : f32 = if x != 0 then 1.0 else 2.0;
+    print("result = {}\n", result);
