I am using an arm gcc cross-toolchain created with OpenEmbedded. Toolchain
version and its dumpspecs are available in attachements. Wrong code for
attached simple testcase is generated when I use -O2 optimization option. When
optimization options are not used or when -O0 is in use then code is generated
correctly. Running testcase is straightforward: compile an example with -O2 and
without it, then run both examples (either on a suitable arm machine or under
qemu) and get two different outputs (OK and WRONG) for two binaries.

This test case works for me on arm-linux-gnueabi with gcc-4.3.5 and gcc-4.4.6,
but fails with current gcc-4.5.2 and gcc-4.6.

So the problem on trunk atleast seems to be in gimple-fold
maybe_fold_or_comparisons and friends where all the comparisons are folded out
into a single boolean node of 1 where ideally the result of the basic block
should be reduced to the (c <= 31) && (x != 9) check . The other 2 equality
comparisons are superfluous.
I won't be able to look at this for a couple of days - hence unassigning
myself.
The problem for this file goes away with -fno-tree-vrp but that's a heavy
weight work around.
cheers

I can verify that the fix for PR46909 fixes the issue on trunk.
I'm looking into 4.5 branch right now.

It doesn't seem to fail for me with the RC for GCC 4.5.2
with -march=armv5te -mthumb
-march=armv5te
-march=armv7-a
-march=armv7-a -mthumb
at -O2, -O3 and -Os
