Date: Fri, 15 Jan 2016 04:00:17 +0000	[thread overview]
Message-ID: <1452830421-77757-6-git-send-email-wangnan0@huawei.com> (raw)

From: Jiri Olsa <jolsa@kernel.org>

To provide FEATURE-DUMP into $(FEATURE_DUMP_COPY)
if defined, with no further action.

Get feature dump of the current build:
  $ make feature-dump
    BUILD:   Doing 'make -j4' parallel build

  Auto-detecting system features:
  ...                         dwarf: [ on  ]

  FEATURE-DUMP file available in FEATURE-DUMP

Get feature dump static build into /tmp/fd file:
  $ make feature-dump FEATURE_DUMP_COPY=/tmp/fd LDFLAGS=-static
    BUILD:   Doing 'make -j4' parallel build

  Auto-detecting system features:
  ...                         dwarf: [ OFF ]

  SNIP

  FEATURE-DUMP file copied into /tmp/fd
