From the gcc docs # # If you use 'asm inline' instead of just 'asm', then for inlining # purposes the size of the asm is taken as the minimum size, ignoring # how many instructions GCC thinks it is. # # For compatibility with older compilers, we obviously want a # # #if [understands asm inline] # #define asm_inline asm inline # #else # #define asm_inline asm # #endif # # But since we #define the identifier inline to attach some attributes, # we have to use an alternate spelling of that keyword. gcc provides # both __inline__ and __inline, and we currently #define both to inline, # so they all have the same semantics. # # We have to free up one of __inline__ and __inline, and the latter is # by far the easiest. # # The two x86 changes cause smaller code gen differences than I'd # expect, but I think we do want the asm_inline thing available sooner # or later, so this is just to get the ball rolling" # # * tag 'compiler-attributes-for-linus-v5.4' of git://github.com/ojeda/linux: # x86: bug.h: use asm_inline in _BUG_FLAGS definitions # x86: alternative.h: use asm_inline for all alternative variants # compiler-types.h: add asm_inline definition # compiler_types.h: don't #define __inline # lib/zstd/mem.h: replace __inline by inline # staging: rtl8723bs: replace __inline by inline # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 227c3e9eb5cf3552c2cc83225df6d14adb05f8e8 # < make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- allmodconfig # make -s -j 120 ARCH=arm64 O=/kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:38: LSE atomics not supported by binutils /kisskb/src/fs/cifs/smb2pdu.c: In function 'SMB2_ioctl_init': /kisskb/src/fs/cifs/smb2pdu.c:2682:19: warning: 'in_data_buf' may be used uninitialized in this function [-Wmaybe-uninitialized] iov[1].iov_base = in_data_buf; ^ In file included from /kisskb/src/include/linux/list.h:9:0, from /kisskb/src/include/linux/wait.h:7, from /kisskb/src/include/linux/wait_bit.h:8, from /kisskb/src/include/linux/fs.h:6, from /kisskb/src/fs/btrfs/send.c:7: /kisskb/src/fs/btrfs/send.c: In function 'process_extent': /kisskb/src/include/linux/kernel.h:37:33: warning: 'clone_src_i_size' may be used uninitialized in this function [-Wmaybe-uninitialized] #define IS_ALIGNED(x, a) (((x) & ((typeof(x))(a) - 1)) == 0) ^ /kisskb/src/fs/btrfs/send.c:5088:6: note: 'clone_src_i_size' was declared here u64 clone_src_i_size; ^ In file included from /kisskb/src/include/linux/wait.h:9:0, from /kisskb/src/include/linux/net.h:19, from /kisskb/src/drivers/infiniband/sw/siw/siw_qp_rx.c:8: /kisskb/src/drivers/infiniband/sw/siw/siw_qp_rx.c: In function 'siw_proc_send': /kisskb/src/include/linux/spinlock.h:288:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized] _raw_spin_unlock_irqrestore(lock, flags); \ ^ /kisskb/src/drivers/infiniband/sw/siw/siw_qp_rx.c:335:16: note: 'flags' was declared here unsigned long flags; ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c: In function 'sh_mobile_i2c_isr': /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:399:26: warning: 'data' may be used uninitialized in this function [-Wmaybe-uninitialized] pd->msg->buf[real_pos] = data; ^ /kisskb/src/drivers/i2c/busses/i2c-sh_mobile.c:372:16: note: 'data' was declared here unsigned char data; ^ /kisskb/src/drivers/soundwire/slave.c:16:12: warning: 'sdw_slave_add' defined but not used [-Wunused-function] static int sdw_slave_add(struct sdw_bus *bus, ^ In file included from /kisskb/src/include/linux/rwsem.h:16:0, from /kisskb/src/include/linux/notifier.h:15, from /kisskb/src/include/linux/clk.h:14, from /kisskb/src/drivers/tty/serial/sh-sci.c:24: /kisskb/src/drivers/tty/serial/sh-sci.c: In function 'sci_dma_rx_submit': /kisskb/src/include/linux/spinlock.h:288:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized] _raw_spin_unlock_irqrestore(lock, flags); \ ^ /kisskb/src/drivers/tty/serial/sh-sci.c:1351:16: note: 'flags' was declared here unsigned long flags; ^ WARNING: "HYPERVISOR_platform_op" [vmlinux] is a static EXPORT_SYMBOL_GPL WARNING: "HYPERVISOR_platform_op" [vmlinux] is a static EXPORT_SYMBOL_GPL Completed OK # rm -rf /kisskb/build/linus_arm64-allmodconfig_arm64-gcc5.4 # Build took: 0:10:09.573337
