Subject: [Bug rtl-optimization/17078] [3.4 regression] Jump into if(0)-substatement fails
Date: Sun, 22 Aug 2004 23:50:00 -0000 [thread overview]

Roger, this looks to be a bug in expand_unreachable_stmt.
In particular, it looks like the return statement is never expanded because it
is considered unreachable due to the earlier goto. However, since the
then-clause of the if-statment falls off the bottom, the return-statement
becomes reachable again. Here, expand_unreachable_if_stmt should be returning
true, but instead returns false.
I've assigned this bug to you.
