Hi!

The following code snippet leads to compile error

volatile long boo = 0;

void
foo (void)
{
  boo++;
}



[]$ /opt/m32c-elf/bin/m32c-elf-gcc -O1   -c test.c -o test.o
unconvertible operand - `Sms'(subreg:HI (mem/v/c/i:SI (symbol_ref:HI ("boo")
[flags 0x2] <var_decl 0x7faa9a811000 boo>) [0 boo+0 S4 A8]) 0)
unconvertible operand - `Sms'(subreg:HI (mem/v/c/i:SI (symbol_ref:HI ("boo")
