* [Bug c/24578]  New: compiler emits call to floorf() instead of floor()

Compiling the following code on MIPS emits a function call to floorf (not
floor).  This is a problem when one's libc does not contain a floorf function.

void func (float *dest, float *src)
{
        *dest = floor (*src);
}

Compile using 'mipsel-linux-uclibc-gcc -O2 -save-temps -c it.c'.

------- Comment #1 from pinskia at gcc dot gnu dot org  2005-10-29 00:52 -------
First this is a target bug and second floorf is a C99 function and really
uclibc should have it.  If you want to declare this a gcc bug, you first need
to add an uclibc target and make it so it does not declare that you have C99
math functions.
