[PATCHv3 00/25] perf tools: Makefile changes

[Jiri Olsa]

hi,
this patchset mostly consists of moving the config 'CHK'
stuff into config/Makefile which will be also used for
kbuild afterwards.

I'm sending now just the Makefile changes separated from
the kbuild stuff, which will come later.

The original RFC is here:
http://marc.info/?l=linux-kernel&m=136484403415600&w=2

The v2 is in here:
http://marc.info/?l=linux-kernel&m=136679633709975&w=2

The patchset is tested via automated make test by running:
  $ make -f tests/make 

v3 changes:
  - tests/make changes suggested by Nmahyung
  - typo fixes suggested by David
  - patch 2 already merged

v2 changes:
  - adding make clean all support (and test)
  - de-CAPSizing the test/make test
  - several line breaking changes, ommiting usage of '\'
  - '?=' operator removal for STRIP
  - tabs to spaces conversion for Makefile non-commands lines

Changes could be reached in here:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/core_make

thanks for comments,
jirka

[PATCH 01/25] perf tools: Add automated make test suite

[Jiri Olsa]

Adding automated test for testing the build process.
To run it you need to be in perf directory or specify
one with PERF variable. It's also possible to specify
optional Makefile to test via MK variable.

Whole suite is executed twice, the second time with
O=/tmp/xxx option added.

To run the whole suite:
  $ make -f tests/make
  - make_pure: cd . && make -f Makefile
    test: test -x ./perf
  - make_clean_all: cd . && make -f Makefile clean all
    test: test -x ./perf
  - make_python_perf_so: cd . && make -f Makefile python/perf.so
    test: test -f ./python/perf.so
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf
  - make_no_libperl: cd . && make -f Makefile NO_LIBPERL=1
    test: test -x ./perf

You see command line for 'make_pure' test right away,
and the output is stored into 'make_pure' file.

To run simple test:
  $ make -f tests/make make_debug
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf

At this moment tests checks for successfull build
and for existence of several built files. Additional
after-build checks could be added.

perf tools: Add automated make test suite

Adding automated test for testing the build process.

To run it you need to be in perf directory or specify one with PERF
variable. It's also possible to specify optional Makefile to test via MK
variable.

Whole suite is executed twice, the second time with O=/tmp/xxx option
added.

To run the whole suite:
  $ make -f tests/make
  - make_pure: cd . && make -f Makefile
    test: test -x ./perf
  - make_clean_all: cd . && make -f Makefile clean all
    test: test -x ./perf
  - make_python_perf_so: cd . && make -f Makefile python/perf.so
    test: test -f ./python/perf.so
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf
  - make_no_libperl: cd . && make -f Makefile NO_LIBPERL=1
    test: test -x ./perf

You see command line for 'make_pure' test right away, and the output is
stored into 'make_pure' file.

To run simple test:
  $ make -f tests/make make_debug
  - make_debug: cd . && make -f Makefile DEBUG=1
    test: test -x ./perf

At this moment tests checks for successfull build and for existence of
several built files. Additional after-build checks could be added.
