Hello,

with gcc 3.2.3, 3.3 branch and mainline, the testcase builds fine for me with a mips-sgi-irix6.5 
cross-compiler, though I don't have checking enabled. Does this problem still occur for you? Does 
it only occur when checking is enabled? Thanks,

Dara

Yes checking is required to trigger the bug and it still occurs, see:

The crash occurs on this code in subreg_hard_regno:

#ifdef ENABLE_CHECKING
  if (!subreg_offset_representable_p (REGNO (reg), GET_MODE (reg),
			  	      SUBREG_BYTE (x), mode))
    abort ();
#endif

The expression in question is:

  (subreg:SF (reg:DI 3 v1) 0)

Is that supposed to be valid?

This crash only occurs with --enable-checking, so I've postponed the bug until
GCC 3.3.2.

According to PR 6221, this is a generic failure on 64-bit targets.

It used to build, but do the wrong thing at runtime, so the fact that it now
aborts at compile time is in some ways an improvement.
