Revision fa136cb5417a554c2b7c85001235e2aace214732 authored by Steven Johnson on 29 August 2023, 16:21:59 UTC, committed by GitHub on 29 August 2023, 16:21:59 UTC 
Ensure that multitarget AOT builds have consistent random sequence (#7717)
 
* Fix CMake test for generator_aot_multitarget

* Ensure that multitarget AOT builds have consistent random numbers

If a Generator uses random_float() (or the int or uint versions), and is used in a multitarget build, we weren't resetting the counters for random generation between each subtarget... meaning that each subtarget would get a different random sequence, leading to some ery hard-to-debug test failures when running on different hardware variants. This PR ensures that the relevant counters are all reset before each subtarget is generated, so that each should see the same sequence of random number generation.

* Update CMakeLists.txt

* Update multitarget_aottest.cpp

* Combine float/uint counters
