--- Comment #5 from Sergey Matyukevich <geomatsi at gmail dot com> 2010-11-28 16:12:47 UTC --- 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.
