--- Comment #8 from Christophe Leroy <christophe.leroy at csgroup dot eu> --- (In reply to Jakub Jelinek from comment #1) > See https://gcc.gnu.org/bugs.html, you haven't provided either preprocessed > source, nor gcc command line options. > inline keyword itself is not a guarantee that the function will be inlined, > it is inlined if it is possible and seems beneficial to the inlining > heuristics. > If you want to always inline, use __attribute__((always_inline)) in addition > to inline keyword. When adding -save-temps as explained in https://gcc.gnu.org/bugs.html I get an error: powerpc64-linux-gcc -Wp,-MMD,fs/.pipe.o.d -nostdinc -isystem /home/opt/gcc-10.1.0-nolibc/powerpc64-linux/bin/../lib/gcc/powerpc64-linux/10.1.0/include -I./arch/powerpc/include -I./arch/powerpc/include/generated -I./include -I./arch/powerpc/include/uapi -I./arch/powerpc/include/generated/uapi -I./include/uapi -I./include/generated/uapi -include ./include/linux/kconfig.h -include ./include/linux/compiler_types.h -D__KERNEL__ -I ./arch/powerpc -Wall -Wundef -Werror=strict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -fshort-wchar -fno-PIE -Werror=implicit-function-declaration -Werror=implicit-int -Wno-format-security -std=gnu89 -mcpu=powerpc -m32 -msoft-float -pipe -ffixed-r2 -mmultiple -mno-readonly-in-sdata -mcpu=860 -mno-altivec -mno-vsx -fno-asynchronous-unwind-tables -mno-string -mbig-endian -fno-delete-null-pointer-checks -Wno-frame-address -Wno-format-truncation -Wno-format-overflow -Wno-address-of-packed-member -O2 -fno-allow-store-data-races -Wframe-larger-than=1024 -fno-stack-protector -Wno-unused-but-set-variable -Wimplicit-fallthrough -Wno-unused-const-variable -fomit-frame-pointer -fno-var-tracking-assignments -g -Wdeclaration-after-statement -Wvla -Wno-pointer-sign -Wno-stringop-truncation -Wno-zero-length-bounds -Wno-array-bounds -Wno-stringop-overflow -Wno-restrict -Wno-maybe-uninitialized -fno-strict-overflow -fno-merge-all-constants -fmerge-constants -fno-stack-check -fconserve-stack -Werror=date-time -Werror=incompatible-pointer-types -Werror=designated-init -fmacro-prefix-map=./= -Wno-packed-not-aligned -DKBUILD_MODFILE='"fs/pipe"' -DKBUILD_BASENAME='"pipe"' -DKBUILD_MODNAME='"pipe"' -c -o fs/pipe.o fs/pipe.c -save-temps powerpc64-linux-gcc.br_real: warning: -pipe ignored because -save-temps specified powerpc64-linux-gcc.br_real: error: unrecognized command line option ‘-fno-allow-store-data-races’
