One page that describes that index and base registers are exchanged in GAS reminds me to a
suggestion I have made for HLASM.
No, not to do the same, but issue a warning when you have
rxinst ra,offset(ra)
instead of
rxinst ra,offset(,ra)

The GNU assembler as used for Linux on IBM Z uses a similar
"raw" format for instructions to that shown in Principles of
Operation, although with some differences. There is more
information about it here, comparing with HLASM:
