[avr-gcc-list] avr-gcc 4.1.1: signbit() causes a compilation abort

Tue, 19 Dec 2006 00:05:42 -0800 

Hi.

avr-gcc (GCC) 4.1.1
Compilation of next program (-W -Wall -Os -S):

    extern int signbit (double);
    int foo (double x)
    {
        return signbit (x);
    }

causes a compilation abort with message:
    internal compiler error: in gen_lowpart_general, at rtlhooks.c:51

Older versions are work:
        3.3.5, 3.4.4  - call of external signbit() function
        4.0.2         - inline-code

Gcc-bugzilla: bug#30243.

Dmitry.
