0c00c3fb - tools build: Add test for missing include

Wed, 23 Sep 2015 10:33:57 +0000

tools build: Add test for missing includeThe current build framework fails to cope with header file removal. Thereason is that the removed header file stays in the .cmd file targetrule and forces the build to fail.This issue is fixed and explained in the following patches.Adding a new build test that simulates header removal.Signed-off-by: Jiri Olsa Cc: David Ahern Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1443004442-32660-3-git-send-email-jolsa@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/build/tests/ex/Build

0bdede8a - tools build: Allow duplicate objects in the object list

Wed, 26 Aug 2015 13:01:03 +0000

tools build: Allow duplicate objects in the object listIt's sometimes useful to specify the object affiliation to multipleconfig options like: libperf-$(CONFIG_X86) += tsc.o libperf-$(CONFIG_AUXTRACE) += tsc.owhile the object itself is linked only once. Adding the support for thisand ignoring duplicate objects in the object list.Suggested-by: Arnaldo Carvalho de Melo Signed-off-by: Jiri Olsa Cc: Adrian Hunter Cc: Sukadev Bhattiprolu Link: http://lkml.kernel.org/r/20150826130103.GF22670@krava.redhat.comSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/build/tests/ex/Build

d7a3d85e - perf build: Do not fail on missing Build file

Fri, 29 May 2015 15:42:58 +0000

perf build: Do not fail on missing Build fileAllow nesting into directories without Build file. Currently we forceinclude of the Build file, which fails the build when the Build file ismissing.We already support empty *-in.o' objects if there's nothing in thedirectory to be compiled, so we can just use it for missing Build filecases.Also adding this case under tests.Reported-by: Rabin Vincent Signed-off-by: Jiri Olsa Cc: David Ahern Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Rabin Vincent Link: http://lkml.kernel.org/r/1432914178-24086-1-git-send-email-jolsa@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/build/tests/ex/Build

c819e2cf - tools build: Add new build support

Mon, 29 Dec 2014 12:51:45 +0000

tools build: Add new build supportAdding new build framework into 'tools/build' to be used by tools.There's no change for actual building at this point, it comes in thenext patches.The idea and more details are explained in the'tools/build/Documentation/Build.txt' file.I adopted everything from the kernel build system, with some changes toallow for multiple binaries build definitions.While the kernel's build output is single image (forget modules) we needto be able to build several binaries/libraries.The basic idea is that sser provides 'Build' files with objectsdefinitions like: perf-y += a.o perf-y += b.o libperf-y += c.o libperf-y += d.oand the build framework outputs files: perf-in.o # a.o, b.o compiled in libperf-in.o # c.o, d.o compiled inSigned-off-by: Jiri Olsa Tested-by: Sukadev Bhattiprolu Tested-by: Will Deacon Cc: Alexis Berlemont Cc: Borislav Petkov Cc: Corey Ashford Cc: David Ahern Cc: Frederic Weisbecker Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-fbj22h4av0otlxupwcmrxgpa@git.kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/build/tests/ex/Build
