How to avoid reference to fplib functions

Note: This was originally posted on 2nd October 2012 at http://forums.arm.com

Hi,
I'm building objects for armv5 with option -fpu=softvfp. All objects are combined to .a library. It seems that compiler puts to my code helper functions such as __ARM_scalbn and __aeabi_lasr. The problem is, that these functions are not hard-coded into my .a lib, references are needed during linking. For some reasons I would like to avoid such behavior and create "stand-alone" .a library, which can be used without fplib and other helpers. In other words, i would like to build-in these functions into library. Is that possible?
Thanks

Do you need fp? If not you could use "--fpu=none"

I need software floating point. But that's tricky, because during linking I don't have access to helpers library. I will give example: library includes function for conversion from float to fixed-point - that's the place where __ARM_scalbn is used. I want to make this function inlined (or something like that) into code. End-user of library should be unaware which functions are hidden under library.

If you only need to hide this from your end users you could statically link the fp helper library into the binary you distribute.
