commit 024d185c10a48339ae06634d0738dd796a159cd8
Author: Dimitar Dimitrov <dimitar@dinux.eu>
Date:   Wed Dec 13 13:08:50 2017 +0000

    This patch enables disassembler_needs_relocs for PRU. It is needed to print correct symbols when disassembling arguments of "call" instructions with a relocation.
    
    opcodes	* disassemble.c: Enable disassembler_needs_relocs for PRU.
    
    gas	* testsuite/gas/pru/extern.s: New test for print of U16_PMEMM
    	relocation.
    	* testsuite/gas/pru/extern.d: New test driver.
