* runtime: fix gr::random API to be fixed-width 64 bit, use XOROSHIRO128+Marcus Müller2021-04-061-7/+6
| | | | | | | | | | | | | | | Seeding being inconsistent between gr::random and things like fastnoise source is an outstanding issue (#1559). Fix that by fixing the API, and pivoting to our built-in XOROSHIRO128+, which is also substantially faster than MT19937. For that purpose, introduce, and python-bind, a wrapper class that can be used with STL distribution shapers. Add a unit test for the (P)RNG. Signed-off-by: Marcus Müller <mmueller@gnuradio.org>
* runtime: Use nanosecond resolution for default random seedThomas Habets2020-04-101-1/+4
| | | | | This exposed some missing forwarding of RNG seed from one object to another, also fixed in this commit.
* runtime: Make random seed default to current time, as documentedThomas Habets2020-04-101-1/+1
| | | | | | | | | | | This is what gnuradio currently documents seeding will do, but it's not what C++ defaults to. See C++11 26.5.3.2, paragraph 3. Default for mersenne twister is constexpr 5489. Or easier, the bottom of https://en.cppreference.com/w/cpp/numeric/random/mersenne_twister_engine

* runtime: random facilities use C++11 (minus boost)Marcus Müller2020-01-021-33/+7
| | | | | | This also includes removing the new/delete for the local objects. C++ doesn't need you to manually new/delete objects with definite lifetime...

| | | | | | | | | | | | | | | | | | | | | * Changed gr-dtv cmake so SSE2 would be detected on both MSVC and GCC compilers * Removed addition of /O2 flag on MSVC builds as it conflicts with /RTC1 flag * Added detection of MSVC 14.0 and added additional filenames to library detection to cover what windows builds the dependencies as. * Additional name options were placed at end so as to not conflict with other builds. * Removed use of not() function and replaced with standard C syntax. The check for zero is to handle the edge case where the random numbers return zero and would cause a div/zero error two lines afterwards. * Add dwrite library for win32 builds for qtgui
