Hi,
this patch fixed an LRA cycling due to secondary reload (Thumb mode).
Notice that this patch is a prerequisite to turn on LRA by default on
ARM. Bootstrapped on a9 and a15 without any regression in the
testsuite as LRA is off by default and with the regression reported in
the thread bellow when LRA is on.

Thanks,

* config/arm/arm.h (THUMB_SECONDARY_INPUT_RELOAD_CLASS): Return NO_REGS
for LRA
?
How can that be correct?
The secondary reload macros/hooks define cases where additional
registers are needed to reload certain forms of rtl. I doubt the use of
LRA completely eliminates the need for secondary reloads.
