Hi,
I could successfully build the 20091105 snapshot of binutils-2.20.51, which has the newly added RX port.
However, on doing regression, the GAS utility failed for "mvfc" and "popc"
instructions. The error message was as follows:
--------------------------------------------------------------------------
binutils-2.20.51/gas/testsuite/gas/rx/mvfc.s: Assembler messages:

---------------------------------------------------------------------------
According to the RX software manual, CPEN is allowed as a source register that can be used with the "mvfc" instruction. But the error message specifies CPEN to be unexpected.
Is it that CPEN is no longer specified as a Control Register?
Could anybody please help me with this issue?
Kindly confirm if this is an issue. If it is then do I need to add it in Bugzilla as well?
