Hi,
On some arm processors, the offset supported in addressing modes is very
small. As a result, the dozens of address induction variables will be
grouped into several groups, rather than only one as on armv7/8. This patch
refines scanning string to avoid test failure on such processors.
It's an obvious change, and test acts as expected. So is it OK? I will
commit it in next 24 hours if there is no objection.
Thanks,
bin
