Arm64EC and plugins (post build step fails)

Are you using /fp:fast (MSVC) or -Ofast (Clang)? If so, the compiler may assume that -0.f is the same as 0.f because it may not follow IEEE-754 strictly. In fact, Clang 18.1.8 tells me that JUCE 8.0.6 itself shows a warning with -Ofast. See:

Windows ClangCL build warnings in 8.0.3

Thanks for looking into it, reuk. The warning only occurs in juce_CharacterFunctions.h which uses constexpr auto inf = std::numeric_limits::infinity(); How do I remove or add ffast-math flag from source files? I’m using projucer to build my plugs. ffast-math is useful for all the graphics stuff, like Fonts drawing etc. The projucer has the Relax IEEE Compliance option, shouldn’t Juce be tested with that option Enabled?
