Disable kcov instrumentation on the same # files where we currently disable gcov and UBSan instrumentation, plus some # additional exclusions which appear necessary to boot on book3e machines. # # Signed-off-by: Andrew Donnellan # Acked-by: Dmitry Vyukov # Tested-by: Daniel Axtens # e6500 # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 2ef9f62a79706208c5a397a9645a45a63be6e718 # < make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 8 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:339:21: note: 'pdeo' was declared here /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x541594) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x541594) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x530f20) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x541594) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x541594) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.0.0-rc2-g2ef9f62a7970 Created: Fri Feb 22 15:33:29 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2639272 Bytes = 2577.41 KiB = 2.52 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.0.0-rc2-g2ef9f62a7970 Created: Fri Feb 22 15:33:29 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2671538 Bytes = 2608.92 KiB = 2.55 MiB Load Address: 00600000 Entry Point: 00601758 Image Name: Linux-5.0.0-rc2-g2ef9f62a7970 Created: Fri Feb 22 15:33:29 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2671767 Bytes = 2609.15 KiB = 2.55 MiB Load Address: 00600000 Entry Point: 006019cc Completed OK # rm -rf /kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc4.6 # Build took: 0:01:02.084822
