* Restored the embedded reduction factor to bruteforce.
This change was present on the GitLab branch but missed out during the transition to GitHub.
This change is intentionally as close as possible to the patch on GitLab.
Fixes#1045
* Added helper functions for bruteforce step and scale.
* Added missing files from 1e4d19b.
* Renamed getTestScale and getTestStep to set*.
* Permit half overflow within allowable ULP
Modify the algorithm for calculating half precision ULP error so
that it duplicates the behaviour of the single precision ULP algorithm,
in regards to allowing overflow within the defined ULP error.
In the case where the test value is infinity, but the reference is
finite, pretend the test value is 63336.0 and calculate the ULP error
against that.
Encountered this while testing half precision `hypot()` in PR !529,
for inputs `hypot(-48864.0, 43648.0)` which has reference
`65519.755799`. With RTE rounding this only just rounds to `65504` as half,
and returning INF is currently infinite ULP error. Using the leniency
introduced by this change however the error is `~0.5` within the `2` ULP
bounds defined by the spec.
* Run clang-format over changes
Code now conforms to style guidelines and allows `check-format.sh` to pass.
* Remove duplicate IsXSubnormal functions
Is{Double,FLoat,Half}Subnormal function duplicates are currently in the codebase.
Fixes#511

* Update conversions.h
* The global variable `gTestFastRelaxed` has state which is used to
control the behaviour of the compiler flag `-cl-fast-relaxed-math` and
the precision testing of relaxed, fp32 and fp64 types. This is confusing
since the global variable is being set and read in different translation
units, making it very difficult to reason about the logic of the brute
force framework. It is particular difficult to follow since the global
variables is cached and then turned off in the case of fp32 and f64 in
order to use the same code path as relaxed testing, after it is then
turned back on.
* Remove uses of the global variable outside of `main.cpp` (the global
variable remains in use within `main.cpp` since it is a command line
option and used to turn of relaxed testing completely). Replace all uses
of the global variable with boolean `relaxedMode` which is passed as a
function paramter but replaces `gTestFastRelaxed` semantically.
Some of the setup functionality is already there in the test harness, so
use that and remove the duplicated code from within the suite.
