[cfe-dev] how to set clang to fastmath?

[YuGiOhJCJ Mailing-List]

Hello,

In order to compile a software (desmume-svn5045 [1]), I need to set clang to fastmath.
It means that I need to change the floating point math mode I use in clang.
If I do this, we told me that I should not encounter this [2] segmentation fault at runtime.

Do you know what option I must give to clang to set it to fastmath please?
(I don't find the option in the manual [3])

Thank you.
Best regards.
