gcc47-pr48163-1.patch
Fix for the expand_debug_expr issue. I was very much surprised that for
data.passed_pointer parameters (those aren't DECL_BY_REFERENCE)
DECL_INCOMING_RTL doesn't reflect where it actually is passed and there is no
way to find the fact that it is pass_by_reference (except for repeating all the
cumulative args/etc. stuff done by function.c).
Either we could use some flag on the PARM_DECL to say this, but I think it is
much better to just adjust DECL_INCOMING_RTL in that case. With the additional
dwarf2out.c change, e.g. on powerpc-linux (32-bit) we are now able to emit
locations for:
struct S { char buf[16]; };
void foo (struct S a, int b, int c, int d, int e, int f, int g, int h, struct S
i)
{
}
even for a and i parameters, which is something we weren't able to do before.
