Linux-2.1.103: Int comp error (alias.c) in bios32.c

[Kurt Garloff]

Hi,

here is a bug in egcs-19880517 (as was in 19980502):
root@kg1:/usr/src/Linux-2.1/linux/arch/i386/kernel # egcc -O2 -D__KERNEL__
 -I/usr/src/Linux-2.1/linux/include -c bios32.c
alias.c:475: Internal compiler error in function rtx_equal_for_memref_p

Just compiling with -O instead of -O2 fixes it.

Here a few lines of alias.c:
          /* It is believed that rtx's at this level will never
	     contain anything but integers and other rtx's,
	     except for within LABEL_REFs and SYMBOL_REFs.  */
        default:
	  abort ();
		   

I believe that it's triggered by (the asm code within?) the function 
static int check_pcibios, 
as this one was changed since 2.1.102.
