[Bug bootstrap/41457] New: [4.5 Regression] Bootstrap failure at revision 152100

On powerpc-apple-darwin9 with the changes I will post on pr41405, bootstrap
fails with:

The file compiles if I remove '-gstrict-dwarf' and '-g' (currently building
libjava at -m64, allow for a couple more hours for bootstrap to complete).

With the similar changes bootstrapping revision 152076 on i686-apple-darwin9.

Subject: Bug 41457

Author: jakub
Date: Thu Sep 24 13:08:11 2009
New Revision: 152119

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=152119
Log:
        PR bootstrap/41457
        * dwarf2out.c (add_const_value_attribute): For HIGH and CONST_FIXED,
        return false instead of gcc_unreachable ().  For CONST return the
        value returned by recursive call instead of always returning true.
        (tree_add_const_value_attribute): Return the value returned by
        add_const_value_attribute instead of always returning true if rtl
        is non-NULL.
