tools lib subcmd: Use str_error_r()

2016-07-12T18:20:30Z

To make it portable to non-glibc systems, that follow the XSI variant instead of the GNU specific one that gets in place when _GNU_SOURCE is defined.

tools: Move utilities.mak from perf to tools/scripts/

2016-03-18T16:57:20Z

As it is used by several other tools, better move it outside tools/perf. Cc: Adrian Hunter Cc: Jiri Olsa Cc: Josh Poimboeuf Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-34s9kue3xq9w5mijdmfrfx8s@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

objtool: Support CROSS_COMPILE

2016-03-03T15:13:00Z

When building with CONFIG_STACK_VALIDATION on a ppc64le host with an x86 cross-compiler, Stephen Rothwell saw the following objtool build errors: DESCEND objtool CC /home/sfr/next/x86_64_allmodconfig/tools/objtool/builtin-check.o CC /home/sfr/next/x86_64_allmodconfig/tools/objtool/special.o CC /home/sfr/next/x86_64_allmodconfig/tools/objtool/elf.o CC /home/sfr/next/x86_64_allmodconfig/tools/objtool/objtool.o MKDIR /home/sfr/next/x86_64_allmodconfig/tools/objtool/arch/x86/insn/ CC /home/sfr/next/x86_64_allmodconfig/tools/objtool/libstring.o elf.c:22:23: fatal error: sys/types.h: No such file or directory compilation terminated. CC /home/sfr/next/x86_64_allmodconfig/tools/objtool/exec-cmd.o CC /home/sfr/next/x86_64_allmodconfig/tools/objtool/help.o builtin-check.c:28:20: fatal error: string.h: No such file or directory compilation terminated. objtool.c:28:19: fatal error: stdio.h: No such file or directory compilation terminated. It fails to build because it tries to compile objtool with the cross-compiler instead of the host compiler. Ensure that it always uses the host compiler by ignoring CROSS_COMPILE. In order to do that properly, the libsubcmd.a library needs to be built in tools/objtool/ rather than tools/lib/subcmd/. The latter directory contains the cross-compiled version which is needed for perf and possibly other tools. Note that cross-compiling for x86 on a _big_ endian system would result in a bunch of false positive objtool warnings during the kernel build because it isn't endian-aware. But that's generally a rare edge case and there haven't been any reports of anybody needing that.

tools subcmd: Add missing NORETURN define for parse-options.h

2016-01-12T15:42:07Z

parse-options.h uses the NORETURN macro without defining it. perf doesn't see a build error because it defines the macro in util.h before including parse-options.h. But any other tool including it will see an error. Define the macro in parse-options.h (if not already defined) so that other tools can include it. Signed-off-by: Josh Poimboeuf Cc: "H.

perf subcmd: Create subcmd library

2015-12-17T17:27:14Z

Move the subcommand-related files from perf to a new library named libsubcmd.a. Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to 'exec-cmd.*' to be consistent with the naming of all the other files.
