[Bug middle-end/21282] New: Converting floor into lfloor built-in function

[loki 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:
