These symbols usually are useless for debugging. # And they might overlap with handwritten symbols. # # Before this change, a dumpstack shows a local symbol for epc: # [ 0.040341][ T0] Hardware name: riscv-virtio,qemu (DT) # [ 0.040376][ T0] epc : .LBB6_14+0x22/0x6a # [ 0.040452][ T0] ra : restore_all+0x12/0x6e # # The simple solution is that we can ignore all local labels prefixed by '.L'. # For handwritten symbols which need to be preserved should drop the '.L' # prefix. # # After this change, the C defined symbol is shown so we can locate the # problematical code immediately: # [ 0.035795][ T0] Hardware name: riscv-virtio,qemu (DT) # [ 0.036332][ T0] epc : trace_hardirqs_on+0x54/0x13c # [ 0.036567][ T0] ra : restore_all+0x12/0x6e # # Signed-off-by: Changbin Du <changbin.du@gmail.com> # Reviewed-by: Nathan Chancellor <nathan@kernel.org> # Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 d4c858643263cfde13f7d937eaff95c2ed87cdf1 # < make -s -j 32 ARCH=m68k O=/kisskb/build/kbuild_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- defconfig # < make -s -j 32 ARCH=m68k O=/kisskb/build/kbuild_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- help # make -s -j 32 ARCH=m68k O=/kisskb/build/kbuild_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- olddefconfig # make -s -j 32 ARCH=m68k O=/kisskb/build/kbuild_m68k-defconfig_m68k-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/m68k-linux/bin/m68k-linux- Completed OK # rm -rf /kisskb/build/kbuild_m68k-defconfig_m68k-gcc11 # Build took: 0:02:44.377076
