HJ,
I think this patch is causing a hppa64-*-* bootstrap failure. I haven't
tracked it down to the specific svn checkin, but I see you have been working
in this area. Compiling a trivial 'int main() {return 0;}' program with
the stage 1 compiler using the latest sources I get:
x.c: In function 'main':
x.c:5: internal compiler error: in instantiate_new_reg, at function.c:1221
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
If I look at (crtl->args.internal_arg_pointer I see:
(reg/f:DI 68)
and if I look at virtual_incoming_args_rtx I see:
(reg/f:DI 61 virtual-incoming-args)
But stack_realign_drap must be false since I hit the gcc_assert.
Has anyone else reported a problem like this? Is there any specific
information I can give you to help in solving this?
