Yet, it is producing some noise. I did a clean build with: $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y W=1 CHECK='' M=drivers/staging/media | grep -v -e " CC " -e " LD " -e " AR " -e " CHK " -e " CALL " -e " UPD " -e "scripts/kconfig/conf " -e " CHECK " >old.log $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y W=1 CHECK='' M=drivers/media| grep -v -e " CC " -e " LD " -e " AR " -e " CHK " -e " CALL " -e " UPD " -e "scripts/kconfig/conf " -e " CHECK " >>old.log and added a new uninitialized "foo" var to a random driver, doing an incremental build with: $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y W=1 CHECK='' | grep -v -e " CC " -e " LD " -e " AR " -e " CHK " -e " CALL " -e " UPD " -e "scripts/kconfig/conf " -e " CHECK " M=drivers/staging/media >new.log $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y W=1 CHECK='' | grep -v -e " CC " -e " LD " -e " AR " -e " CHK " -e " CALL " -e " UPD " -e "scripts/kconfig/conf " -e " CHECK " M=drivers/media >new.log Then, I ran the script: $ linux-log-diff old.log new.log *** ERRORS *** *** WARNINGS *** 1 warning regressions: + drivers/media/dvb-frontends/dibx000_common.c: warning: unused variable 'foo' [-Wunused-variable]: => 22:5 3 warning improvements: - ./arch/x86/include/asm/bitops.h: warning: asm output is not an lvalue: 430:22 => - drivers/staging/media/atomisp/pci/atomisp2/css2400/hive_isp_css_common/host/mmu_private.h: warning: function 'mmu_reg_load' with external linkage has definition: 35:30 => - drivers/staging/media/atomisp/pci/atomisp2/css2400/hive_isp_css_common/host/mmu_private.h: warning: function 'mmu_reg_store' with external linkage has definition: 24:26 => It detected the "foo" var warning, but it outputs 3 warning improvements on files that were not even built the second time. -- Thanks, Mauro
