Honza, This patch causes a bootstrap failure when building libstdc++ on AIX:
In file included from /farm/dje/src/src/libstdc++-v3/include/precompiled/stdc++.h:94:0: /tmp/20110423/powerpc-ibm-aix5.3.0.0/libstdc++-v3/include/valarray:1163:1: internal compiler error: vector VEC(tree,base) index domain error, in evaulate_conditions_for_edge at ipa-inline-analysis.c:466 I do not know if this is related to the WPA failure reported by Toon. Also, I think you mean "evaluate" not "evaulate" in the description and new function names. Thanks, David
