But the # problem in question is limited to only the 'asm goto with outputs' # cases, so instead of re-introducing the old workaround as-is, let's # rename and limit the workaround to just that much less common case. # # It looks like there are at least two separate issues that all hit in # this area: # # (a) some versions of gcc don't mark the asm goto as 'volatile' when it # has outputs: # # https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98619 # https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110420 # # which is easy to work around by just adding the 'volatile' by hand. # # (b) Internal compiler errors: # # https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110422 # # which are worked around by adding the extra empty 'asm' as a # barrier, as in the original workaround. # # but the problem Sean sees may be a third thing since it involves bad # code generation (not an ICE) even with the manually added 'volatile'. # # but the same old workaround works for this case, even if this feels a # bit like voodoo programming and may only be hiding the issue. # # Reported-and-tested-by: Sean Christopherson <seanjc@google.com> # Link: https://lore.kernel.org/all/20240208220604.140859-1-seanjc@google.com/ # Cc: Nick Desaulniers <ndesaulniers@google.com> # Cc: Uros Bizjak <ubizjak@gmail.com> # Cc: Jakub Jelinek <jakub@redhat.com> # Cc: Andrew Pinski <quic_apinski@quicinc.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 4356e9f841f7fbb945521cef3577ba394c65f3fc # make -s -j 32 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 32 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 32 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 32 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all;
