2017-06-06kbuild: simplify silent build (-s) detectionMasahiro Yamada1-7/+1
This allows to detect -s (--silent) option without checking GNU Make version. As commit e36aaea28972 ("kbuild: Fix silent builds with make-4") pointed out, GNU Make 4.x changed the way/order it presents the command line options into MAKEFLAGS. In Make 3.8x, 's' is always the first in a group of short options. The group may be prefixed with '-' in some cases. In Make 4.x, 's' is always the last in a group of short options. As commit e6ac89fabd03 ("kbuild: Correctly deal with make options which contain an 's'") addressed, we also need to deal with long options that contain 's', like --warn-undefined-variables. Test cases: [1] command line input: make --silent -> MAKEFLAGS for Make 3.8x: s -> MAKEFLAGS for Make 4.x : s [2] command line input: make -srR -> MAKEFLAGS for Make 3.8x: sRr -> MAKEFLAGS for Make 4.x : rRs [3] command line input: make -s -rR --warn-undefined-variables -> MAKEFLAGS for Make 3.8x: --warn-undefined-variables -sRr -> MAKEFLAGS for Make 4.x : rRs --warn-undefined-variables My idea to cater to all the cases more easily is to filter out long options (--%), then search 's' with $(findstring ...). This way will be more future-proof even if future versions of Make put 's' in the middle of the group. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2017-01-26tools build: Add tools tree support for 'make -s'Josh Poimboeuf1-1/+11
When doing a kernel build with 'make -s', everything is silenced except the objtool build. That's because the tools tree support for silent builds is some combination of missing and broken. Three changes are needed to fix it: - Makefile: propagate '-s' to the sub-make's MAKEFLAGS variable so the tools Makefiles can see it. - tools/scripts/Makefile.include: fix the tools Makefiles' ability to recognize '-s'. The MAKE_VERSION and MAKEFLAGS checks are copied from the top-level Makefile. This silences the "DESCEND objtool" message. - tools/build/Makefile.build: add support to the tools Build files for recognizing '-s'. Again the MAKE_VERSION and MAKEFLAGS checks are copied from the top-level Makefile. This silences all the object compile/link messages.

2016-07-22tools build: Fix objtool build with ARCH=x86_64Josh Poimboeuf1-0/+32
The objtool build fails in a cross-compiled environment on a non-x86 host with "ARCH=x86_64": tools/objtool/objtool-in.o: In function `decode_instructions': tools/objtool/builtin-check.c:276: undefined reference to `arch_decode_instruction' We could override the ARCH environment variable and change it back to x86, similar to what the objtool Makefile was doing before; but it's tricky to override environment variables consistently. Instead, take a similar approach used by the Linux top-level Makefile and introduce a SRCARCH Makefile variable which evaluates to "x86" when ARCH is either "x86_64" or "x86".

2012-11-19tools: Honour the O= flag when tool build called from a higher MakefileDavid Howells1-4/+13
Honour the O= flag that was passed to a higher level Makefile and then passed down as part of a tool build. To make this work, the top-level Makefile passes the original O= flag and subdir=tools to the tools/Makefile, and that in turn passes subdir=$(O)/$(subdir)/foodir when building tool foo in directory $(O)/$(subdir)/foodir (where the intervening slashes aren't added if an element is missing). For example, take perf. This is found in tools/perf/. Assume we're building into directory ~/zebra/, so we pass O=~/zebra to make. Dependening on where we run the build from, we see: make run in dir $(OUTPUT) dir ======================= ================== linux ~/zebra/tools/perf/ linux/tools ~/zebra/perf/ linux/tools/perf ~/zebra/ and if O= is not set, we get: make run in dir $(OUTPUT) dir ======================= ================== linux linux/tools/perf/ linux/tools linux/tools/perf/ linux/tools/perf linux/tools/perf/ The output directories are created by the descend function if they don't already exist.
