| 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] |
