Currently R_PPC64_UADDR64 are # detected by arch/powerpc/tools/relocs_check.sh and expected not to work. # Below is a simple chunk to trigger this behaviour (this disables # optimization for the demonstration purposes only, this also happens with # -O1/-O2 when CONFIG_PRINTK_INDEX=y, for example): # # \#pragma GCC push_options # \#pragma GCC optimize ("O0") # struct entry { # const char *file; # int line; # } __attribute__((packed)); # static const struct entry e1 = { .file = __FILE__, .line = __LINE__ }; # static const struct entry e2 = { .file = __FILE__, .line = __LINE__ }; # ... # prom_printf("e1=%s %lx %lx\n", e1.file, (unsigned long) e1.file, mfmsr()); # prom_printf("e2=%s %lx\n", e2.file, (unsigned long) e2.file); # \#pragma GCC pop_options # # This adds support for UADDR64 for 64bit. This reuses __dynamic_symtab # from the 32bit code which supports more relocation types already. # # Because RELACOUNT includes only R_PPC64_RELATIVE, this replaces it with # RELASZ which is the size of all relocation records. # # Signed-off-by: Alexey Kardashevskiy # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20220309061822.168173-1-aik@ozlabs.ru # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 d799769188529abc6cbf035a10087a51f7832b6b # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=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_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:5257:warning: override: reassigning to symbol PPC64 .config:5258:warning: override: reassigning to symbol PPC_DISABLE_WERROR .config:5260:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:5262:warning: override: reassigning to symbol GCC_PLUGINS # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/fs/jffs2/xattr.c: In function 'jffs2_build_xattr_subsystem': /kisskb/src/fs/jffs2/xattr.c:887:1: error: the frame size of 1072 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] 887 | } | ^ cc1: all warnings being treated as errors make[3]: *** [/kisskb/src/scripts/Makefile.build:288: fs/jffs2/xattr.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/scripts/Makefile.build:550: fs/jffs2] Error 2 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [/kisskb/src/Makefile:1831: fs] Error 2 make[1]: *** Waiting for unfinished jobs.... make: *** [Makefile:219: __sub-make] Error 2 Command 'make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc9 # Build took: 0:02:15.664649
