Somehow, the frv-linux gcc did not like that and I am guessing that instead of splitting it started copying. The first report about this is at: https://lists.01.org/pipermail/kbuild-all/2015-July/010527.html. Reported-by: Fengguang Wu Cc: Andi Kleen Fixes: 866ced950bcd ("kbuild: Support split debug info v4") Signed-off-by: Sudip Mukherjee --- I will try and see if this can work with frv and if still fails I will open a bug report with gcc. But meanwhile this is the easiest option to solve build failure of frv. Hi Fengguang, As frv arch will start building with this patch after a long time, it will give new warnings which your script will consider to be new warnings introduced by this patch. lib/Kconfig.debug | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/Kconfig.debug b/lib/Kconfig.debug index 18ffa80..2bdb1c6 100644 --- a/lib/Kconfig.debug +++ b/lib/Kconfig.debug @@ -165,7 +165,7 @@ config DEBUG_INFO_REDUCED config DEBUG_INFO_SPLIT bool "Produce split debuginfo in .dwo files" - depends on DEBUG_INFO + depends on DEBUG_INFO && !FRV help Generate debug info into separate .dwo files.
