2016-12-05tools build: Move tabs to spaces where suitableJiri Olsa
We've been hit several times by a Makefile bug where line indented by tab was falsely considered as target command. We prevent this by always using space indentation for everything except for the target commands.

2016-12-05tools build: Make the .cmd file more readableJiri Olsa
Putting extra line between dependencies and cmd_* definition to make it more readable. Before: $ cat .builtin-top.o.cmd ... /home/jolsa/kernel/linux-perf/tools/include/linux/stringify.h \ /home/jolsa/kernel/linux-perf/tools/include/linux/time64.h cmd_builtin-top.o := gcc -Wp,-MD,./.builtin-top.o.d -Wp,-MT,builtin-... ...

2016-12-05tools build: Fix objtool build with clangPeter Foley
Clang doesn't support multiple arguments being passed to -Wp, so split them.

2016-11-14tools build: Add CFLAGS_REMOVE_* supportJiri Olsa
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.

2016-10-05tools build: Support compiling C++ source fileWang Nan
Add new rule to compile .cpp file to .o use g++. C++ support is required for built-in clang and LLVM support. Linker side support will be introduced by following commits.

2016-10-03tools build: Add support for host programs formatJiri Olsa
In some cases, like for fixdep and shortly for jevents, we need to build a tool to run on the host that will be used in building a tool, such as perf, that is being cross compiled, so do like the kernel and provide HOSTCC, HOSTLD and HOSTAR to do that.

2015-09-28tools build: Make the fixdep helper part of the build processJiri Olsa
Making the fixdep helper to be invoked within dep-cmd. Each user of the build framework needs to make sure fixdep exists before executing the build itself. If the build doesn't find fixdep, it falls back to the old style dependency tracking.

2015-02-11tools build: Add new build supportJiri Olsa
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>
