PA-RISC bug in gas

[Dan Bonachea]

Hi - I'm trying to use gas 2.15 on PA-RISC, and I want to issue an ldcws 
instruction like:

    ldcws,co 0(%r20), %r19

which is accepted by the HP assembler, but gas barfs with:

   Error: Invalid Short Load/Store Completer.

gas apparently doesn't like the cache control hint completor, which is 
critical for semaphore performance on PA-RISC. I've tried every reasonable 
combination of characters for the completer that I can think of, and nothing 
seems to work.

Here's a patch to 2.15 which I believe fixes the issue:
