Subject: [Bug rtl-optimization/38644] [4.4/4.5/4.6/4.7 Regression] Optimization flag -O1 -fschedule-insns2 causes wrong code

--- Comment #53 from Sebastian Huber <sebastian.huber@embedded-brains.de> 2011-10-24 13:06:03 UTC ---
I tested the above patch proposed by Mikael Pettersson (from 2010-05-26, more
than one year ago) with GCC 4.6 20111021. It still fixes the test case
provided by Dave Murphy (from 2008-12-27, nearly three years ago). I run the
GCC C and C++ testsuite with the arm-rtemseabi4.11 target and the results are
identical with and without the patch. Even if we have no perfect solution yet,
it would be very kind if someone can check in an intermediate fix.
