+ * Reporter: Toshiyasu Morita <[e-mail]>
+ * Summary: [3.4 Regression] [-fnew-ra] ICE compiling channel.i on sh
+ * Keywords: ice-on-valid-code
+ * Description:
+ * [ICE] when channel.i from stress-1.17 is compiled with options:
+ * -O2 -m4 -fnew-ra
+ * ...
+ * The CFG code gets confused by the addition of a USE insn after a sibcall.
+ * Sibcalls are supposed to end the block (and the function!), so the fact
+ * that we have an instruction following one (even if its fake) is confusing.
+ *
+ * testcase tweaked by [e-mail]
