[issue25934] ICC compiler: ICC treats denormal floating point numbers as 0.0

[Zachary Ware]

Zachary Ware added the comment:

Here's a patch that specifies /fp:strict if it looks like ICC is being used for the build.  It also adds a convenient property for checking whether it's an ICC build ($(ICCBuild)).  This doesn't change anything for MSVC builds but allows ICC builds to pass test_math, test_cmath, test_audioop, etc.; as such, it should be applied to all three branches.

As far as replacing the non-constants that MSVC doesn't like, I'm +1 but not too bothered about it.  I'm happy to test if anyone supplies a patch for it.
