            Bug ID: 16118
           Summary: gdb.base/frame-args.exp PowerPC/Linux failures
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: macro@linux-mips.org
            Target: powerpc-linux-gnu

I see failures from gdb.base/frame-args.exp on the powerpc-linux-gnu
target:

(gdb) frame 1
#1  0x100006dc in call_me (i=3, f=5, s=<error reading variable: value has been
optimized out>, ss=0xbffff7d8, u=<error reading variable: value has been
optimized out>, e=green) at .../gdb/testsuite/gdb.base/frame-args.c:40
40        break_me ();
(gdb) FAIL: gdb.base/frame-args.exp: frame 1 with print frame-arguments set to
all

and:

(gdb) frame 1
#1  0x100006dc in call_me (i=3, f=5, s=<error reading variable: value has been
optimized out>, ss=0xbffff7d8, u=<error reading variable: value has been
optimized out>, e=green) at .../gdb/testsuite/gdb.base/frame-args.c:40
40        break_me ();
(gdb) FAIL: gdb.base/frame-args.exp: frame 1 with print frame-arguments set to
scalars

clearly because <error reading variable: value has been optimized out> is
printed rather than just <optimized out>.  The discussion here:

http://sourceware.org/ml/gdb-patches/2012-08/msg00715.html
http://sourceware.org/ml/gdb-patches/2012-09/msg00000.html

and commit 2603f7eeca78caeef1f362eccebe7cd4b589ba41 may be related,
although in my case GCC 4.8.1 is used.  Other targets seem unaffected.
