Yes, thought so ;-).

Yes, this looks good (such a patch is certainly above my current knowledge
of egcs :-) ) and works fine on powerpc-linux-gnu, I just bootstrapped and
checked the mainline with it. You just missed a small bit in
if (DEFAULT_ABI == ABI_V4 || DEFAULT_ABI == ABI_SOLARIS)
rs6000_sysv_varargs_p = 1;
if (! no_rtl)
- save_area = plus_constant (frame_pointer_rtx, RS6000_VARARGS_OFFSET);
+ save_area = plus_constant (virtual_stack_vars_rtx,
Can you check in this stuff in that shape? And maybe the second part (the
gnuplot fix) of my patch if it is OK and the testcase?
