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/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 227c3e9eb5cf3552c2cc83225df6d14adb05f8e8 # < make -s -j 120 ARCH=arm O=/kisskb/build/linus_exynos_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- exynos_defconfig # make -s -j 120 ARCH=arm O=/kisskb/build/linus_exynos_defconfig_arm CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi- /kisskb/src/kernel/rcu/srcutree.c: In function 'init_srcu_struct_fields': /kisskb/src/kernel/rcu/srcutree.c:140:32: warning: 'levelspread[]' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/rcu/srcutree.c:88:6: note: 'levelspread[]' was declared here /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2591:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1852:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/soc/soc-pcm.c: In function 'soc_pcm_trigger': /kisskb/src/sound/soc/soc-pcm.c:1074:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/sound/soc/soc-pcm.c: In function 'soc_pcm_bespoke_trigger': /kisskb/src/sound/soc/soc-pcm.c:1092:9: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/crypto/sha512_generic.c: In function 'sha512_transform': /kisskb/src/crypto/sha512_generic.c:149:1: warning: the frame size of 1184 bytes is larger than 1024 bytes [-Wframe-larger-than=] /kisskb/src/net/mac80211/mlme.c: In function 'ieee80211_rx_mgmt_beacon': /kisskb/src/net/mac80211/mlme.c:1576:3: warning: 'pwr_level_cisco' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c:1533:6: note: 'pwr_level_cisco' was declared here /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] WARNING: "return_address" [vmlinux] is a static EXPORT_SYMBOL_GPL WARNING: "return_address" [vmlinux] is a static EXPORT_SYMBOL_GPL Completed OK # rm -rf /kisskb/build/linus_exynos_defconfig_arm # Build took: 0:01:14.622831
