Hello all,

I met a problem, when I used gcc for sh4.

------ system ------
FreeBSD 4.5-RELEASE 
- gcc configuration -
Configured with: ../gcc-3.2.2/configure --target=sh-unknown-elf
--with-gnu-as --with-gnu-ld --enable-languages=c
Thread model: single
gcc version 3.2.2   
--------------------  
Sample source code.   
---- sh4vargtst.c ----
int main()
{
    unsigned int x=1;
    int bs=10, c;
    
    c = x % bs;
    
    return( c);
}
--------------------
/tmp/gcc/xgcc -B/tmp/gcc/ -g -m4 -little -c sh4vargtst.c -o sh4vargtst.o
--------------------
The program result is c = -9 .

I think udivsi3_i4 in gcc/config/sh/lib1funcs.asm is wrong.
When the same program is compiled with -mno-implicit-fp,
it run correct.


thanks for any help
