Hi Guys,
I am checking in the patch below to the mainline and 4.7 branch
sources to fix a typo in the comparesi3_extend patterns in the rx.md
file. Operand 0 is an input operand but it had an = modifier applied
to it. This confused gcc's internals and resulted in several ICEs in
the gcc testsuite.
Cheers
Nick
