- Reply-to: gcc-bugzilla at gcc dot gnu dot org
I have segfault for the following c code:
extern double floor (double);
long foo (float f)
{
return (long) floor (f);
}
Command line:
arm-elf-gcc -c -O1 1.c
Output message:
1.c: In function 'foo':
1.c:5: internal compiler error: in expand_builtin_int_roundingfn, at builtins.c:2225
...
The environment was configured with:
binutils-2.14/configure --target=arm-elf
gcc/configure --target=arm-elf --enable-language=c
newlib-1.12.0/configure --target/arm-elf
I have found the same problem for {i386, m68k, mips, ppc}-elf.
The bug appeared after the following patch:
