[PATCH 01/36] tools build: Add new build support
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 stole 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 Tested-by: Sukadev Bhattiprolu Tested-by: Will Deacon Cc: Alexis Berlemont Cc: Arnaldo Carvalho de Melo Cc: Borislav Petkov Cc: Corey Ashford Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian --- tools/build/Build.include | 81 ++ tools/build/Documentation/Build.txt | 132 tools/build/Makefile.build | 97 ++ tools/build/tests/ex/Build | 8 +++ tools/build/tests/ex/Makefile | 23 +++ tools/build/tests/ex/a.c| 5 ++ tools/build/tests/ex/arch/Build | 2 + tools/build/tests/ex/arch/e.c | 5 ++ tools/build/tests/ex/arch/f.c | 5 ++ tools/build/tests/ex/b.c| 5 ++ tools/build/tests/ex/c.c| 5 ++ tools/build/tests/ex/d.c| 5 ++ tools/build/tests/ex/empty/Build| 0 tools/build/tests/ex/ex.c | 19 ++ tools/build/tests/run.sh| 42 tools/perf/MANIFEST | 1 + 16 files changed, 435 insertions(+) create mode 100644 tools/build/Build.include create mode 100644 tools/build/Documentation/Build.txt create mode 100644 tools/build/Makefile.build create mode 100644 tools/build/tests/ex/Build create mode 100644 tools/build/tests/ex/Makefile create mode 100644 tools/build/tests/ex/a.c create mode 100644 tools/build/tests/ex/arch/Build create mode 100644 tools/build/tests/ex/arch/e.c create mode 100644 tools/build/tests/ex/arch/f.c create mode 100644 tools/build/tests/ex/b.c create mode 100644 tools/build/tests/ex/c.c create mode 100644 tools/build/tests/ex/d.c create mode 100644 tools/build/tests/ex/empty/Build create mode 100644 tools/build/tests/ex/ex.c create mode 100755 tools/build/tests/run.sh diff --git a/tools/build/Build.include b/tools/build/Build.include new file mode 100644 index ..4c8daaccb82a --- /dev/null +++ b/tools/build/Build.include @@ -0,0 +1,81 @@ +### +# build: Generic definitions +# +# Lots of this code have been borrowed or heavily inspired from parts +# of kbuild code, which is not credited, but mostly developed by: +# +# Copyright (C) Sam Ravnborg , 2015 +# Copyright (C) Linus Torvalds , 2015 +# + +### +# Convenient variables +comma := , +squote := ' + +### +# Name of target with a '.' as filename prefix. foo/bar.o => foo/.bar.o +dot-target = $(dir $@).$(notdir $@) + +### +# filename of target with directory and extension stripped +basetarget = $(basename $(notdir $@)) + +### +# The temporary file to save gcc -MD generated dependencies must not +# contain a comma +depfile = $(subst $(comma),_,$(dot-target).d) + +### +# Check if both arguments has same arguments.
