This # allows us to use this in the kernel for ftrace purposes. A new script is # added under arch/powerpc/tools/ to help detect if nops are emitted after # the function local entry point, or before the global entry point. # # With -fpatchable-function-entry, we no longer have the profiling # instructions generated at function entry, so we only need to validate # the presence of two nops at the ftrace location in ftrace_init_nop(). We # patch the preceding instruction with 'mflr r0' to match the # -mprofile-kernel ABI for subsequent ftrace use. # # This changes the profiling instructions used on ppc32. The default -pg # option emits an additional 'stw' instruction after 'mflr r0' and before # the branch to _mcount 'bl _mcount'. This is very similar to the original # -mprofile-kernel implementation on ppc64le, where an additional 'std' # instruction was used to save LR to its save location in the caller's # stackframe. Subsequently, this additional store was removed in later # compiler versions for performance reasons. The same reasons apply for # ppc32 so we only patch in a 'mflr r0'. # # Signed-off-by: Naveen N Rao <naveen@kernel.org> # Reviewed-by: Christophe Leroy <christophe.leroy@csgroup.eu> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://msgid.link/68586d22981a2c3bb45f27a2b621173d10a7d092.1687166935.git.naveen@kernel.org # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 cad771f9a27ef0f598026c6902b1d0be733194a9 # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-next_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- defconfig # < make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-next_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-next_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-next_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: warning: arch/sparc/vdso/vdso-note.o: missing .note.GNU-stack section implies executable stack /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: warning: arch/sparc/vdso/vdso32/vdso-note.o: missing .note.GNU-stack section implies executable stack /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker WARNING: modpost: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
