Boost versions prior to 1.68 appear to have a bug where a decorator to
denote a test as disabled is not honored when affixed to a data-driven
test case, which is how the benchmarks in convert_test are skipped when
the unit test is run. (The tests take some time to complete and we don't
want them running with every CI pass.)
This commit adds an alternative benchmark skipping mechanism when Boost
<1.68 is used. The benchmark test cases perform a runtime check for the
user-provided `--benchmark` command-line option. If not found, the test
case returns prematurely. If found, the test case will execute. Note
that because `--benchmark` is a command-line option specific to this
test, and not to Boost, the options must follow `--` in the command
line in order to take effect: `convert_test -- --benchmark`.
This commit adds Boost test cases for benchmarking each of the existing
conversions that are tested in convert_test. The benchmarks do take some
time, and we do not want to run they as part of every CI run, so they
are marked with a test decorator that disables the benchmark by default.
To run the benchmarks, invoke convert_test with `--run-test=+benchmark*`
to explicitly enable all disabled tests that begin with the word
'benchmark'. Individual benchmark test cases can be enabled by
specifying the full name of the benchmark test or by crafting a wildcard
that includes all benchmark test cases of interest.
This commit implements some minor cleanup of various converter- and
convert test-related code:
* Improves the log messages regarding which converter was returned for a
request.
* Modifies the result checking code in the converter tests to only
report an out-of-range sample error once, rather than reporting every
out-of-range sample encountered during the test. This vastly cuts down
on the output when a conversion has failed.
* Adds a function `reverse_converter()` which, given a
`convert::id_type` describing a conversion from C1 to C2, returns a
`convert::id_type` describing the reverse conversion (C2 to C1).
* Removes two redundant test cases from the converter test.
The difference between the _chdr converters and the _item32_ converters
is that the former do not require item32 boundaries, they do not require
endianness swapping, and they don't use IQ swapping either.
This is possible because the FPGA will do byte-swapping.
Replaced with initialization lists.
Note: uhd::dict does not work with initializer lists without making
changes to said data structure. This commit has no functional changes,
so keeping the boost::assigns for uhd::dict.
Create missing sc12-sc16 and sc16-sc12 type converters. To avoid
replicating the full sc12 converter class object, overload the
converter calls with C++11 std::enable_if metafunctions. When
used with std::is_floating and std::is_integral templates, this
allow a single template interface with compile time function
selection and static type checking.
Note the below std::enable_if interface is confusing, but quite
effective in this case.
typename enable_if<is_floating_point<type>::value>::type* = NULL
Fixes: #966
Related: #967, #1721
- Also removes all references to boost/cstdint.hpp and replaces it with
stdint.h (The 'correct' replacement would be <cstdint>, but not all of our
compilers support that).
