Hi,
the ICE does not reproduce for me, but from backtrace it seems quite clear
that the following fix should work:
Index: cgraph.c
===================================================================
--- cgraph.c (revision 221707)
+++ cgraph.c (working copy)
@@ -1516,7 +1516,7 @@ cgraph_update_edges_for_call_stmt_node (
if (e)
{
/* Keep calls marked as dead dead. */
- if (e->callee
+ if (new_call && e->callee
&& DECL_BUILT_IN_CLASS (e->callee->decl) == BUILT_IN_NORMAL
&& DECL_FUNCTION_CODE (e->callee->decl) == BUILT_IN_UNREACHABLE)
{
It is late here, so I will return to it only at morning. If the patch fixes
the
ICE and passes testing, please just go ahead and commit it.
