From: Masahiro Yamada Date: Fri, 15 Dec 2017 15:28:42 +0000 (+0900) Subject: kconfig: display recursive dependency resolution hint just once X-Git-Url: https://jxself.org/git/?p=carl9170fw.git;a=commitdiff_plain;h=8208d00a70bdf17ba50edea6cf1a79a3fd93744a;hp=a542100e78834c07080b393b00484fc2be46212f kconfig: display recursive dependency resolution hint just once Commit 1c199f2878f6 ("kbuild: document recursive dependency limitation / resolution") probably intended to show a hint along with "recursive dependency detected!" error, but it missed to add {...} guard, and the hint is displayed in every loop of the dep_stack traverse, annoyingly. This error was detected by GCC's -Wmisleading-indentation when switching to build-time generation of lexer/parser. config/symbol.c: In function ‘sym_check_print_recursive’: config/symbol.c:1150:3: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation] if (stack->sym == last_sym) ^~ config/symbol.c:1153:4: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’ fprintf(stderr, "For a resolution refer to Documentation/kbuild/kconfig-language.txt\n"); ^~~~~~~ I could simply add {...} to surround the three fprintf(), but I rather chose to move the hint after the loop to make the whole message readable.
