H A D | Makefile.build | diff 6f0fa58e459642b16901521cc58ac474b787ec5b Fri May 19 13:42:30 CEST 2017 Masahiro Yamada <yamada.masahiro@socionext.com> kbuild: simplify silent build (-s) detection
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.
