IPA problem with asm sources

Can I use IPA (Interprocedural Analysis) if I have any pure assembler files in project? I always got warning due linking:
The following function(s) are called, but no IPA information is available:

Linking without IPA

Hi La00,

The problem here is since you’re including code not compiled with IPA, the compiler has incomplete information about your program. Since this could lead to incorrect code generation, the compiler must be conservative and continue compilation without using the IPA information.

However, you can use the IPA flag “-Mipa=safe” to force the compiler to continue with the IPA compilation even when there is missing information. Because there is potential for errors, please test you code carefully after using this flags.

Hope this helps,

Thank you Mat
