Ian,

I am having a bootstrap failure on the PA64 platform (hppa64-hp-hpux11.11) with this patch. I have verified the failure starts with version 121453 and the symptoms are that I cannot compile the following test program:

typedef float TFtype __attribute__ ((mode (TF)));
TFtype __powitf2 (TFtype x) { return 1/x; }

$ obj_gcc/gcc/cc1 -quiet -O2 x.c x.c: In function '__powitf2': x.c:3: internal compiler error: in invalidate, at cse.c:1831

The failure does not happen with the PA32 HP-UX target (or the IA64 HP-UX target). If there is more information I can provide to help figure out what is going on here I would be happy to provide it.
