      perf tools: Warn the user about how to enable libunwind support · 7a0447d6
      由 Arnaldo Carvalho de Melo 提交于 
      When one has libunwind installed somewhere the perf tools build process
doesn't expects it to be, this happens:

  [acme@ssdandy linux]$ make O=/tmp/build/perf -C tools/perf/ install-bin
  make: Entering directory `/home/acme/git/linux/tools/perf'
    BUILD:   Doing 'make -j8' parallel build
  config/Makefile:312: No libunwind found, disabling post unwind support.  Please install libunwind-dev[el] >= 1.1

  Auto-detecting system features:
  <SNIP>
  ...                     libunwind: [ OFF ]

Change the message so that it tells how to use a non-standard libunwind
install directory:

  config/Makefile:312: No libunwind found, disabling post unwind support.  Please install libunwind-dev[el] >= 1.1 and/or set LIBUNWIND_DIR

  [acme@ssdandy linux]$ make LIBUNWIND_DIR=/opt/libunwind-git/ O=/tmp/build/perf -C tools/perf/ install-bin
  make: Entering directory `/home/acme/git/linux/tools/perf'
    BUILD:   Doing 'make -j8' parallel build

      perf tools: Factor features display code · 0695e57b
      由 Jiri Olsa 提交于 
      Currently the we display all detected features/libraries by following
rules:

 - if one of the features is missing
 - if it's build from clean tree

This patch changes changes this behavior in several ways.

- We no longer display all detected features, only detected libraries
  are displayed by default:

  $ make
    BUILD:   Doing 'make -j4' parallel build

  Auto-detecting system features:
  ...                         dwarf: [ on  ]
  ...                         glibc: [ on  ]
  ...                          gtk2: [ on  ]
  ...                      libaudit: [ on  ]
  ...                        libbfd: [ on  ]
  ...                        libelf: [ on  ]
  ...                       libnuma: [ on  ]
  ...                       libperl: [ on  ]
  ...                     libpython: [ on  ]
  ...                      libslang: [ on  ]
  ...                     libunwind: [ on  ]

  The assumption is, that above libraries are the most interesting part
of the detection, while we don't care much about detection of on-exit
support.

- If all above libraries are detected, the default is not shown on
  subsequent builds.

- If one of the above libraries is missing, the detection output is
  forced.

- The features status is stored in PERF-FEATURES file and the detection
  output is forced in case the there's difference between the file
  contents and currently detected features.

- If you want to see all detected features, you can use VF=1 make
  variable, that forces the detected features output.

  $ make VF=1

      perf tools: Fix bison OUTPUT directories dependency · da237ed0
      由 Jiri Olsa 提交于 
      The bison and flex C objects don't have dependency for creating output
directories.

This could lead to build failure if the one of those objects is picked
up by make to be build as the first one (reported by Arnaldo).

Also following make fails:
  $ rm -rf /tmp/krava; mkdir /tmp/krava; make O=/tmp/krava util/pmu-bison.o
  BUILD:   Doing 'make -j4' parallel build
  [ SNIP ]
  BISON    /tmp/krava/util/pmu-bison.c
  FLAGS:   * new build flags or prefix
bison: /tmp/krava/util/pmu-bison.output: cannot open: No such file or directory
make[1]: *** [/tmp/krava/util/pmu-bison.c] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [util/pmu-bison.o] Error 2

Adding bison objects dependency for output directories (flex objects
depends on bisons').

This fixies the make_util_pmu_bison_o_O make test.
