GCC 16 flagged this while GCC 15 did not. On some targets, the macros used to ensure the floating point context was fully in use with task specific values would result in set but unused warnings. Tweaked the tests and macros as needed to eliminate the warnings.
tmtests
This directory contains the RTEMS Classic API Timing Test Suite. The tests in this directory are used to measure the execution time of RTEMS directive and some critical internal functions. The results of these test are useful for comparison of RTEMS performance
- between versions of RTEMS
- between different boards
- across different architectures
These tests attempt to benchmark RTEMS as the user would. They measure the execution time for a directive (under various circumstances) from the time RTEMS is entered until it is executed. Where possible, the time is the average of at least 100 invocations of the directive.
The accuracy of the times reported by these benchmarks is very dependent on the resolution of the timer being used. It is also important to insure that all sources of hardware interrupts are disabled during execution of the tests. This insures that the directive time reported does not include any interrupt time.
