+Subject: [PATCH] test-float: Make variables global
+
+Latest clang ( clang 16+ ) is able to optimize everything out when -O2 is used and as
+a result build succeeds and test output comes out to be wrong. Therefore
+make the variables global, so clang does not optimize away the functions
+
+Upstream-Status: Backport [https://github.com/ColinIanKing/stress-ng/commit/e299eb60a3a029e975304cc43045aea6ab1fad70]
