--- Comment #7 from Dlang Bot <dlang-bot at dlang.rocks> ---
@ibuclaw created dlang/phobos pull request #8642 "std.math.hardware: Fix broken
IEEE FP flags tests" mentioning this issue:

- std.math.hardware: Fix broken IEEE FP flags tests

  1. The `pragma(inline, false)` doesn't do what the author thinks it does
     (Issue 23520).
  2. Change that introduced `blockopt` seems to have a slight
     misunderstanding about what constant propagation is (`a /= 0.0L` can
     always be constant propagated regardless of what surrounds it).
