* tools build: Add CFLAGS_REMOVE_* supportJiri Olsa2016-11-141-2/+4
| | | | | | | | | | | | | | | | | | | | | | Adding support to remove options from final CFLAGS for both object file and build target. It's now possible to remove CFLAGS options like: CFLAGS_REMOVE_krava.o += -Wstrict-prototypes Committer notes: This comes from the kernel's kbuild infrastructure, the subset that is supported in tools/ is being documented at tools/build/Documentation/Build.txt.

* tools build: Build fixdep helper from perf and basic libsJiri Olsa2015-09-281-0/+7
| | | | | | | | | | | | | Adding the fixdep target into the Makefile.include to ease up building of fixdep helper, that needs to be built before we dive in to the build itself. The user can invoke the fixdep target to build the helper.

* tools build: Allow duplicate objects in the object listJiri Olsa2015-08-261-0/+1
| | | | | | | | | | | | | | | | | | It's sometimes useful to specify the object affiliation to multiple config options like: libperf-$(CONFIG_X86) += tsc.o libperf-$(CONFIG_AUXTRACE) += tsc.o while the object itself is linked only once. Adding the support for this and ignoring duplicate objects in the object list.

* tools build: Add new build supportJiri Olsa2015-02-111-0/+139
Adding new build framework into 'tools/build' to be used by tools. There's no change for actual building at this point, it comes in the next patches. The idea and more details are explained in the 'tools/build/Documentation/Build.txt' file. I adopted everything from the kernel build system, with some changes to allow for multiple binaries build definitions. While the kernel's build output is single image (forget modules) we need to be able to build several binaries/libraries. The basic idea is that sser provides 'Build' files with objects definitions like: perf-y += a.o perf-y += b.o libperf-y += c.o libperf-y += d.o and the build framework outputs files: perf-in.o # a.o, b.o compiled in libperf-in.o # c.o, d.o compiled in Signed-off-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com> Tested-by: Will Deacon <will.deacon@arm.com> Cc: Alexis Berlemont <alexis.berlemont@gmail.com> Cc: Borislav Petkov <bp@alien8.de> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-fbj22h4av0otlxupwcmrxgpa@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
