2014-03-27Referencing a function's address on PowerPC64 ELFv2Alan Modra11-43/+143
ELFv2 needs to create plt entries in a non-PIC executable for an address reference to a function defined in a shared object. It's possible that an object file has no features that distinguish it as ELFv1 or ELFv2, eg. an object only containing data. Such files need to be handled like those that are known to be ELFv2. However, this unnecessarily creates plt entries for the analogous ELFv1 case, so arrange to set output abi version earlier, and use the output abi version to further distinguish ambiguous input files. bfd/ * elf64-ppc.c (ppc64_elf_check_relocs): Account for possibly needed plt entries when taking the address of functions for abiversion == 0 (ie. unknown) as well as abiversion == 2.

2014-03-26Skip tests on completion and readline when readline lib isn't usedYao Qi10-136/+198
The completion feature and other features on readline depend on the readline library. However, readline library is not always used, for example, running testsuite like make check RUNTESTFLAGS="--host_board=local-remote-host" the input stream is not a tty, and GDB doesn't use readline library as a result. This patch is to skip tests on completion and readline if 'show editing' is off, which means readline isn't used. Note that some tests in gdb.base/completion.exp test command complete, which isn't related to readline, so these tests aren't affected by readline library. This patch also moves these tests up, run them unconditionally, and run the rest if readline library is used. gdb/testsuite: 2014-03-26 Yao Qi <yao@codesourcery.com> * lib/gdb.exp (readline_is_used): New proc. * gdb.base/completion.exp: Move tests on command complete up.

2014-03-24Fix PR breakpoints/16101: gdb.base/dprintf.exp agent-printf failures with ↵Hui Zhu4-34/+77
non-Z0-supporting gdbservers After a previous patch that was committed by Pedro (0000e5cc), trying to set a dprintf with with a GDBserver that doesn't support agent commands at all now throws an error. But the dprintf tests still fail with some GDBserver targets because they doesn't try to handle the case of the server reporting support for breakpoint commands, but not be able to use those in combination with Z0 (because Z0 isn't actually supported, for example): FAIL: gdb.base/dprintf.exp: 1st dprintf, agent FAIL: gdb.base/dprintf.exp: 2nd dprintf, agent FAIL: gdb.base/dprintf.exp: dprintf info 2 (pattern 4) Similarly for the MI test. This patch makes the tests handle this scenario. Tested with native, and native gdbserver on x86_64 Fedora 17. Also tested with the native-gdbserver.exp board hacked with: set GDBFLAGS "${GDBFLAGS} -ex \"set remote breakpoint-commands off\"" (actually, "set remote breakpoint-commands off" is presently broken, so this was on top of a fix for that command.) which results in: (gdb) PASS: gdb.base/dprintf.exp: 2nd dprintf, gdb set dprintf-style agent warning: Target cannot run dprintf commands, falling back to GDB printf warning: Target cannot run dprintf commands, falling back to GDB printf (gdb) UNSUPPORTED: gdb.base/dprintf.exp: set dprintf style to agent gdb.sum: Running target native-gdbserver Running ../../../src/gdb/testsuite/gdb.base/dprintf.exp ...

2014-03-22Move the traceframe_available_memory code from memory_xfer_partial_1 down to ↵Yao Qi5-143/+185
the targets As a follow-up to [PATCH 7/8] Adjust read_value_memory to use to_xfer_partial https://sourceware.org/ml/gdb-patches/2014-02/msg00384.html this patch moves traceframe_available_memory down to the target side. After this patch, the gdb core code is cleaner, and code on handling unavailable memory is moved to remote/tfile/ctf targets. In details, this patch moves traceframe_available_memory code from memory_xfer_partial_1 to remote target only, so remote target still uses traceframe_info mechanism to check unavailable memory, and use remote_ops to read them from read-only sections. We don't use traceframe_info mechanism for tfile and ctf target, because it is fast to iterate all traceframes from trace file, so the summary information got from traceframe_info is not necessary.
