Subject: [PATCH v2] inline fail reporting: reporting inline fail caused by
overwritable function
When inline failed because of callee is overwritable, gcc will not report it
in dump file as other inline failing cases do. This patch correct this.
ChangeLog:
2013-04-05 Zhouyi Zhou <yizhouz...@ict.ac.cn>
* cif-code.def (OVERWRITABLE): correct the comment for overwritable
function
* ipa-inline.c (can_inline_edge_p): let dump mechanism report the
inline fail caused by
overwritable function
