| 2 | |
| 3 | This patch fixes two compilation errors with original |
| 4 | dhrystone sources: |
| 5 | * Redefinition of times() with wrong return type |
| 6 | - Fixed by commenting out the unnecessary redefinition |
| 7 | * Undefined identifier HZ |
| 8 | - Originally HZ was supposed to be the clock frequency |
| 9 | value for times() |
| 10 | - For Linux, the frequency should come from sysconf |
| 11 | - This patch defines global varible HZ and initializes |
| 12 | it from sysconf |
| 13 | |
| 14 | Additionally, this patch adds a simple Makefile. |
