* Added support to test half floats with printf calls (issue #142, printf)
* Added corrections related to rounding and casting halfs (issue #142, printf)
* Reusing similar function (issue #142, printf)
* Corrected path without cl_khr_fp16 support (issue #142, printf)
* Cosmetic fix for order of vector tests (issue #142, printf)
* Added correction related to vendor test review (issue #142, printf)
* Moved float tests that expect limits into their own sub-test.
These are harder to test generically on the CPU so have them be their own test which will retain hard-coded reference results.
* Remove unused variable.
* Switched reference result type from (char**) to (vector::const char*)
* printf: generate reference results where possible #673#675
The reference results had two issues:
- They did not take into account the rounding mode of the device.
- Scientific notation results did not have trailing zero's, meaning that the exponent could be a single digit, despite the requirement being at least two digits.
This change introduces runtime generated reference results for types with numerical representations (float, int, hex, etc) where a direct mapping to standard C99 (sn)printf is possible to execute on the CPU.
* Trim leading zeroes from the exponent when verifying result #675.
There is no limit on how many leading zeros may be in the exponent, so strip them all.
* Switched to using get_default_rounding_mode.
Some of the setup functionality is already there in the test harness, so
use that and remove the duplicated code from within the suite.
