commit 0d7b2549024f66cb98dd173b6f339673df1b0ea1
Author: Andreas Arnez <arnez@linux.vnet.ibm.com>
Date:   Mon Nov 17 15:22:48 2014 +0000

    Use 2-byte instead of 4-byte NOP on S390 in 'bp-permanent' test case
    
    The bp-permanent test case assumes that a NOP is exactly as long as a
    software breakpoint.  This is not the case for the S390 "nop"
    instruction, which is 4 bytes long, while a software breakpoint is
    just 2 bytes long.  The "nopr" instruction has the right size and can
    be used instead.
    
    Without this patch the test case fails on S390 when trying to continue
    after SIGTRAP on the permanent breakpoint:
    
      ...
      Continuing.
    
      Program received signal SIGILL, Illegal instruction.
      test () at /home/arnez/src/binutils-gdb/gdb/testsuite/gdb.base/bp-permanent.c:40
      40	  NOP; /* after permanent bp */
      (gdb)
      FAIL: gdb.base/bp-permanent.exp: always_inserted=off, sw_watchpoint=0:
        basics: stop at permanent breakpoint
    
    With this patch the test case succeeds without any FAILs.
    
    gdb/testsuite/ChangeLog:
    
    	* gdb.base/bp-permanent.c (NOP): Define as 2-byte instead of
    	4-byte instruction on S390.
