kbuild,gcov: simplify kernel/gcov/Makefile more

2015-01-09T16:25:44Z

CONFIG_GCOV_FORMAT_3_4 / _4_7 / _AUTODETECT are exclusive. Compare the CC version only when _AUTODETECT is enabled. This change should have no impact. Signed-off-by: Masahiro Yamada Cc: Peter Oberparleiter Signed-off-by: Michal Marek

kbuild,gcov: simplify kernel/gcov/Makefile

2015-01-09T16:25:44Z

Kbuild descends into kernel/gcov/ directory only when CONFIG_GCOV_KERNEL is enabled. (See kernel/Makefile) CONFIG_GCOV_KERNEL check can be omitted in kernel/gcov/Makefile. Signed-off-by: Masahiro Yamada Cc: Peter Oberparleiter Signed-off-by: Michal Marek

kbuild,gcov: remove unnecessary workaround

2015-01-09T16:25:44Z

Since commit 371fdc77af44 (kbuild: collect shorthands into scripts/Kbuild.include), scripts/Makefile.clean includes scripts/Kbuild.include. The workaround and the comment block in kernel/gcov/Makefile are no longer necessary. Signed-off-by: Masahiro Yamada Cc: Peter Oberparleiter Signed-off-by: Michal Marek

kbuild: do not add $(call ...) to invoke cc-version or cc-fullversion

2015-01-09T16:25:44Z

The macros cc-version, cc-fullversion and ld-version take no argument. It is not necessary to add $(call ...) to invoke them. Signed-off-by: Masahiro Yamada Acked-by: Helge Deller [parisc] Signed-off-by: Michal Marek

gcov: enable GCOV_PROFILE_ALL from ARCH Kconfigs

2014-12-13T20:42:51Z

Following the suggestions from Andrew Morton and Stephen Rothwell, Dont expand the ARCH list in kernel/gcov/Kconfig. Instead, define a ARCH_HAS_GCOV_PROFILE_ALL bool which architectures can enable. set ARCH_HAS_GCOV_PROFILE_ALL on Architectures where it was previously allowed + ARM64 which I tested.

gcov: add ARM64 to GCOV_PROFILE_ALL

2014-10-29T23:33:14Z

Following up the arm testing of gcov, turns out gcov on ARM64 works fine as well. Only change needed is adding ARM64 to Kconfig depends. Tested with qemu and mach-virt Signed-off-by: Riku Voipio Acked-by: Peter Oberparleiter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

ARM: 8153/1: Enable gcov support on the ARM architecture

2014-09-26T13:39:57Z

Enable gcov support for ARM based on original patches by David Singleton and George G. Davis Riku - updated to patch to current mainline kernel. The patch has been submitted in 2010, 2012 - for symmetry, now in 2014 too. https://lwn.net/Articles/390419/ http://marc.info/?l=linux-arm-kernel&m=133823081813044 v2: remove arch/arm/kernel from gcov disabled files Cc: Andrey Ryabinin Cc: Naresh Kamboju Acked-by: Arnd Bergmann Signed-off-by: Riku Voipio Signed-off-by: Vincent Sanders Signed-off-by: Russell King

kernel/gcov/fs.c: remove unnecessary null test before debugfs_remove

This fixes checkpatch warning: WARNING: debugfs_remove(NULL) is safe this check is probably not required Signed-off-by: Fabian Frederick Cc: Peter Oberparleiter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

gcov: add support for GCC 4.9

2014-06-10T22:34:46Z

This patch handles the gcov-related changes in GCC 4.9: A new counter (time profile) is added. The total number is 9 now. A new profile merge function __gcov_merge_time_profile is added. See gcc/gcov-io.h and libgcc/libgcov-merge.c For the first change, the layout of struct gcov_info is affected. For the second one, a dummy function is added to kernel/gcov/base.c similarly.
