Previously # it would take the warning condition, x, and double negate it before # converting the result to int, and passing that int to the underlying # inline asm. ie: # # #define WARN_ON(x) ({ # int __ret_warn_on = !!(x); # if (__builtin_constant_p(__ret_warn_on)) { # ... # } else { # BUG_ENTRY(PPC_TLNEI " %4, 0", # BUGFLAG_WARNING \| BUGFLAG_TAINT(TAINT_WARN), # "r" (__ret_warn_on)); # # The asm then does a full register width comparison with zero and traps # if it is non-zero (PPC_TLNEI). # # The new code instead passes the full expression, x, with some arbitrary # type, to the inline asm: # # #define WARN_ON(x) ({ # ... # do { # if (__builtin_constant_p((x))) { # ... # } else { # ... # WARN_ENTRY(PPC_TLNEI " %4, 0", # BUGFLAG_WARNING \| BUGFLAG_TAINT(TAINT_WARN), # __label_warn_on, "r" (x));

# } # # The full disassembly shows that clang has not generated any code to # apply the "& KNODE_DEAD" to the n_klist pointer, which is surprising. # # Nathan filed an LLVM bug [2], in which Eli Friedman explained that clang # believes it is only passing a single bit to the asm (ie. a bool) and so # the mask of bit 0 with 1 can be omitted, and suggested that if we want # the full 64-bit value passed to the inline asm we should cast to a # 64-bit type (or 32-bit on 32-bits). # # In fact we already do that for BUG_ENTRY(), which was added to fix a # possibly similar bug in 2005 in commit 32818c2eb6b8 ("[PATCH] ppc64: Fix # issue with gcc 4.0 compiled kernels"). # # So cast the value we pass to the inline asm to long. # # For GCC this appears to have no effect on code generation, other than # causing sign extension in some cases. # # [1]: http://lore.kernel.org/r/YSa1O4fcX1nNKqN/@Ryzen-9-3900X.localdomain # [2]: https://bugs.llvm.org/show_bug.cgi?id=51634 # # Fixes: 1e688dd2a3d6 ("powerpc/bug: Provide better flexibility to WARN_ON/__WARN_FLAGS() with asm goto") # Reported-by: Nathan Chancellor <nathan@kernel.org> # Reviewed-by: Nathan Chancellor <nathan@kernel.org> # Tested-by: Nathan Chancellor <nathan@kernel.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20210901112522.1085134-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 e432fe97f3e5de325b40021e505cce53877586c5 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:5101:warning: override: reassigning to symbol STANDALONE .config:5103:warning: override: reassigning to symbol MODULE_SIG .config:5105:warning: override: reassigning to symbol PPC64 .config:5108:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD .config:5112:warning: override: reassigning to symbol TRIM_UNUSED_KSYMS # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/clk/xilinx/xlnx_vcu.c: In function 'xvcu_register_clock_provider': /kisskb/src/drivers/clk/xilinx/xlnx_vcu.c:524:9: warning: missing braces around initializer [-Wmissing-braces] struct clk_parent_data parent_data[2] = { 0 };
