lrint lrintf problems

[Bernd Roesch <nospamname at web dot de>]

Hi, 

I see in compiler source there is in builtin.c lrint lrintf.so the gcc need
no extern linker lib when i understand right. 

But get linker error when use them.I test compiler 3.4.0 4.3.2 and 4.4.0

I also link with libgcc.but does not help

also my includes-fixed/math.h

contain a declaration but it is long int.
extern long int lrint _PARAMS((double)); 

This mean 64 bit int ?

But i use 32 bit 68k compiler and as far i see lrint return a long in docu.

only solution i find short is add in library.

 long lrintf(float x)
{
  return (long)x;
}

But when do this code, then there should be used current rounding.68k for
example support a simple fmove.l fp0,d0 and use current rounding to convert
from float.

But gcc (test with 4.3.2)output this code in -m68020 -m68881 -03.

FMOVE.S #+1.2344999E+4,FP0 
FADD.L  D4,FP0             
FINTRZ.X FP0               
FMOVE.L FP0,-(A7)          

But i think there is no fintrz need and this code do the same job and use
the correct rounding setting.

FMOVE.S #+1.2344999E+4,FP0 
FADD.L  D4,FP0             
FMOVE.L FP0,-(A7)          

Or i am wrong ?.Or is "return (long)x;" specified to always round to zero ?

How can i then implement lrint func without asm Code ? 

please help
