From de481560eb0bd9d940b90311eba85711e4b1150b Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 30 Apr 2009 12:32:04 -0400 Subject: kconfig: keep config.gz around even if CONFIG_IKCONFIG_PROC is not set If CONFIG_IKCONFIG is set but CONFIG_IKCONFIG_PROC is not, then gcc will optimize the config.gz out, because nobody uses it. This patch adds "__used" to the config.gz data to keep it around so that code like extract-ikconfig can still find it. [ Impact: allow extract-ikconfig to find config.gz ] Signed-off-by: Steven Rostedt --- kernel/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'kernel/Makefile') diff --git a/kernel/Makefile b/kernel/Makefile index 2093a69..d0c84e6 100644 --- a/kernel/Makefile +++ b/kernel/Makefile @@ -119,7 +119,7 @@ $(obj)/config_data.gz: .config FORCE $(call if_changed,gzip) quiet_cmd_ikconfiggz = IKCFG $@ - cmd_ikconfiggz = (echo "static const char kernel_config_data[] = MAGIC_START"; cat $< | scripts/bin2c; echo "MAGIC_END;") > $@ + cmd_ikconfiggz = (echo "static const char kernel_config_data[] __used = MAGIC_START"; cat $< | scripts/bin2c; echo "MAGIC_END;") > $@ targets += config_data.h $(obj)/config_data.h: $(obj)/config_data.gz FORCE $(call if_changed,ikconfiggz) -- cgit v1.1
