# We've had issues with gcc and 'asm goto' before, and we created a # 'asm_volatile_goto()' macro for that in the past: see commits # 3f0116c3238a ("compiler/gcc4: Add quirk for 'asm goto' miscompilation # bug") and a9f180345f53 ("compiler/gcc4: Make quirk for # asm_volatile_goto() unconditional"). # # Then, much later, we ended up removing the workaround in commit # 43c249ea0b1e ("compiler-gcc.h: remove ancient workaround for gcc PR # 58670") because we no longer supported building the kernel with the # affected gcc versions, but we left the macro uses around. # # Now, Sean Christopherson reports a new version of a very similar # problem, which is fixed by re-applying that ancient workaround. 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 160 ARCH=sh O=/kisskb/build/linus_defconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- defconfig # < make -s -j 160 ARCH=sh O=/kisskb/build/linus_defconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 160 ARCH=sh O=/kisskb/build/linus_defconfig_sh4-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 160 ARCH=sh O=/kisskb/build/linus_defconfig_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/mm/cache-shx3.c:18:13: warning: no previous prototype for 'shx3_cache_init' [-Wmissing-prototypes] 18 \| void __init shx3_cache_init(void) \| ^~~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/init.c:99:29: warning: no previous prototype for 'l2_cache_init' [-Wmissing-prototypes] 99 \| void __attribute__ ((weak)) l2_cache_init(void) \| ^~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh4/fpu.c:389:6: warning: no previous prototype for 'float_raise' [-Wmissing-prototypes] 389 \| void float_raise(unsigned int flags) \| ^~~~~~~~~~~ /kisskb/src/arch/sh/kernel/cpu/sh4/fpu.c:394:5: warning: no previous prototype for 'float_rounding_mode' [-Wmissing-prototypes] 394 \| int float_rounding_mode(void) \| ^~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/flush-sh4.c:106:13: warning: no previous prototype for 'sh4__flush_region_init' [-Wmissing-prototypes] 106 \| void __init sh4__flush_region_init(void) \| ^~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sh/mm/cache-sh4.c:384:13: warning: no previous prototype for 'sh4_cache_init' [-Wmissing-prototypes] 384 \| void __init sh4_cache_init(void) \| ^~~~~~~~~~~~~~ /kisskb/src/arch/sh/kernel/return_address.c:49:7: warning: no previous prototype for 'return_address' [-Wmissing-prototypes] 49 \| void return_address(unsigned int depth) \| ^~~~~~~~~~~~~~ /kisskb/src/kernel/locking/spinlock.c:68:17: warning: no previous prototype for '__raw_spin_lock' [-Wmissing-prototypes] 68 \| void __lockfunc __raw_##op##_lock(locktype##_t lock) \ \| ^~~~~~ /kisskb/src/kernel/locking/spinlock.c:126:1: note: in expansion of macro 'BUILD_LOCK_OPS' 126 \| BUILD_LOCK_OPS(spin, raw_spinlock);
