A fair amount of documentation and comments # have also been added, clarified or removed; and the headers are now # more readable, which should help kernel developers in general. # # The series was triggered due to the move to gcc >= 4.6. In turn, this # series has also triggered Sparse to gain the ability to recognize # __has_attribute on its own. # # Finally, the __nonstring variable attribute series has been also # applied on top; plus two related patches from Nick Desaulniers for # unreachable() that came a bit afterwards" # # tag 'compiler-attributes-for-linus-4.20-rc1' of https://github.com/ojeda/linux: # compiler-gcc: remove comment about gcc 4.5 from unreachable() # compiler.h: update definition of unreachable() # Compiler Attributes: ext4: remove local __nonstring definition # Compiler Attributes: auxdisplay: panel: use __nonstring # Compiler Attributes: enable -Wstringop-truncation on W=1 (gcc >= 8) # Compiler Attributes: add support for __nonstring (gcc >= 8) # Compiler Attributes: add MAINTAINERS entry # Compiler Attributes: add Doc/process/programming-language.rst # Compiler Attributes: remove uses of __attribute__ from compiler.h # Compiler Attributes: KENTRY used twice the "used" attribute # Compiler Attributes: use feature checks instead of version checks # Compiler Attributes: add missing SPDX ID in compiler_types.h # Compiler Attributes: remove unneeded sparse (__CHECKER__) tests # Compiler Attributes: homogenize __must_be_array # Compiler Attributes: remove unneeded tests # Compiler Attributes: always use the extra-underscores syntax # Compiler Attributes: remove unused attributes # < /opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 e468f5c06b5ebef3f6f3c187e51aa6daab667e57 # < make -s -j 8 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- randconfig KCONFIG_SEED=0xFA1272EA # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_GCC_PLUGIN_CYC_COMPLEXITY=n # Added to kconfig CONFIG_GCC_PLUGIN_SANCOV=n # Added to kconfig CONFIG_GCC_PLUGIN_LATENT_ENTROPY=n # yes \n \| make -s -j 8 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 8 ARCH=x86_64 O=/kisskb/build/linus-rand_x86_64-randconfig_um-x86_64 CROSS_COMPILE=/opt/cross/kisskb/fe-x86-64-core-i7-2017.05/bin/x86_64-linux- In file included from /kisskb/src/include/linux/wait.h:7:0, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/f2fs/node.c:8: /kisskb/src/fs/f2fs/node.c: In function '__set_nat_cache_dirty': /kisskb/src/include/linux/list.h:63:13: warning: 'head' may be used uninitialized in this function [-Wmaybe-uninitialized] next->prev = new; ^ /kisskb/src/fs/f2fs/node.c:237:24: note: 'head' was declared here struct nat_entry_set *head; ^ /kisskb/src/drivers/gpu/drm/amd/amdgpu/soc15.c: In function 'soc15_set_ip_blocks': /kisskb/src/drivers/gpu/drm/amd/amdgpu/soc15.c:542:3: warning: #warning "Enable CONFIG_DRM_AMD_DC for display support on SOC15."
