Hi,
Attached patch intends to fix bug 55019 which is exposed on 4.7 branch.
Although this bug can't be reproduced on trunk, I think this fix is still
useful to make trunk more robust. Tested with trunk regression test on
cortex-m0 and cortex-m3, no regression found. Also tested with various
benchmark like Dhrystone/coremark/eembc_v1 on cortex-m0, no regression on
performance and code size. Is it ok to go upstream and 4.7 branch?
BR,
Terry

The test isn't thumb1 specific. In fact, it isn't even ARM specific.
So I think it should be moved to gcc.dg.
Otherwise OK for trunk and 4.7.
