| 4 | Subject: [PATCH] test-float: Make variables global |
| 5 | |
| 6 | Latest clang ( clang 16+ ) is able to optimize everything out when -O2 is used and as |
| 7 | a result build succeeds and test output comes out to be wrong. Therefore |
| 8 | make the variables global, so clang does not optimize away the functions |
