What would cause a single instruction function to NOT be inlined?

Post Body
My architecture has an absolute value instruction. I can see in the disassembly that both abs and std::abs compile down to this single instruction. But sometimes it’s a function call to an abs function which only has two instructions: abs and ret, and sometimes it’s inlined. I’m using -O3 on gcc... any idea why a function call would be generated for such a small function?
