fabs not being inlined?

[NaN]

module ohreally;

import std.math;

float foo(float y, float x)
{
     float ax = fabs(x);
     float ay = fabs(y);
     return ax*ay/3.142f;
}

====>

float ohreally.foo(float, float):
         push    rax
         movss   dword ptr [rsp + 4], xmm1
         call    pure nothrow @nogc @safe float 
std.math.fabs(float)@PLT
         movss   dword ptr [rsp], xmm0
         movss   xmm0, dword ptr [rsp + 4]
         call    pure nothrow @nogc @safe float 
std.math.fabs(float)@PLT
         mulss   xmm0, dword ptr [rsp]
         divss   xmm0, dword ptr [rip + .LCPI0_0]
         pop     rax
         ret

Is there something I need to do to get fabs() inlined?
