-Subject: [PATCH] Allow ppc64 events to be specified with or without _GRP<n>
- suffix
-
-All events for IBM PowerPC server processors (except CYCLES) have
-a _GRP<n> suffix. This is because the legacy opcontrol profiler
-can only profile events in the same group (i.e., having the same
-_GRP<n> suffix). But operf has no such restriction because it
-can multiplex events; thus, so we should allow the user to pass
-event names without the _GRP<n> suffix.

-Subject: [PATCH] Change configure to look for libpfm4 function first; then
- fallback to libpfm3
-
-This change only affects ppc64 architecture, since it's the only
-architecture that uses libpfm to obtain the event hex code to pass
-to perf_event_open.
-
-There were bugs in libpfm3 pertaining to POWER7 event definitions that
-have been fixed in libpfm4. So it's likely that some IBM POWER7 users
-may want to install libpfm4 and build oprofile to link with it. For
-example, if libpfm4 were installed in /usr/local, the user would invoke
-oprofile's configure thusly:
-
-LDFLAGS="-L/usr/local/lib64" CPPFLAGS="-I/usr/local/include" ./configure
-
-But if the user happens to also have libpfm3 already installed in /usr,
-then the current order of config tests would result in choosing the libpfm3
-library. This logic seems wrong. The configure checking should go from most
-recent to older library versions. This patch changes the order of checking
-so the libpfm4 library would be found first.

- architecture
-
-The configure check to determine whether we should use libpfm or not
-is intended only for the ppc64 architecture, but was incorrectly
-hitting on the ppc32 architecture, too. Not only that, but it was using
-'uname' which is not a good idea in cross-compile situtations.
-
-Then, aside from that, we had several instances in the source code
-of the following:
- #if (defined(__powerpc__) || defined(__powerpc64__))
-which incorrectly included ppc32 architecutre also, when it was intended
-for use as PPC64 architecture.
-
-This patch fixes both errors.

-Subject: [PATCH] Fix up configure to handle architectures that do not
- implement perf_event_open
-
-This patch fixes the following problems:
-
-1) The configure script allows the user to pass a location to kernel
-headers (via --with-kernel option) such that, even if the running
-kernel does not have perf_events support, it may be possible to
-build operf (e.g., in cross-compile environments). But the message
-'This kernel does not have perf_events support; falling back to legacy
-oprofile' was being displayed inappropriately in such cases. This
-patch changes the configure script so that the "falling back to
-legacy oprofile" message will only be displayed if we're running
-on a kernel that does not have perf_events support AND the user
-did not pass specify the "--with-kernel" option.
-
-2) Some architectures don't even implement the perf_event_open syscall, so the
-configure script must do more than checking kernel version and whether or not
-perf_event.h is present in order to decide if perf_events is supported.
-This patch provides that extra capability.
-
-These problems were reported by Tony Jones <tonyj@suse.com>.

-Subject: [PATCH] Handle early perf_events kernel without
- PERF_RECORD_MISC_GUEST* macros
-
-In very early versions of perf_events kernel subsystem, the
-PERF_RECORD_MISC_GUEST_KERNEL and PERF_RECORD_MISC_GUEST_USER
-macros (in perf_event.h) were not yet defined. This patch adds
-a configure check to determine when it's OK for source code to refer
-to those macros.
-
-This patch also does some minor cleanup of the configure script
-help and warning messages relating to the --with-kernel option.

+Subject: [PATCH] Tidy powerpc64 bfd target check
+
+Testing for a bfd_target vector might (will!) break. See
+https://sourceware.org/ml/binutils/2014-04/msg00283.html
+
+It's safer to ask BFD for the target name. I left the direct target
+vector checks in configure tests, and updated them, even though the
+target vector is no longer used in oprofile code, because a run-time
+configure test for powerpc64 support in bfd:
+ #include <bfd.h>
+ int main(void)
+ { return !bfd_find_target("elf64-powerpc", (void *)0); }
+unfortunately isn't possible when cross-compiling.
+
+The bfd_target vector tests could be omitted if we aren't bothered by
+the small runtime overhead of a strncmp on targets other than
+powerpc64.
+
+ * libutil++/bfd_support.cpp (get_synth_symbols): Don't check for
+ ppc64 target vector, use bfd_get_target to return the target
+ name instead.
+ * m4/binutils.m4: Modernize bfd_get_synthetic_symtab checks to
+ use AC_LINK_IFELSE. Check for either powerpc_elf64_vec or
+ bfd_elf64_powerpc_vec.
