Hi Linus, Please pull this patch series which make us take advantage of `asm inline`.
You will encounter an easy merge conflict on `init/Kconfig` due to the (already merged) arm64 tree. Cheers, Miguel The following changes since commit f74c2bb98776e2de508f4d607cd519873065118e: Linux 5.3-rc8 (2019-09-08 13:33:15 -0700) are available in the Git repository at: https://github.com/ojeda/linux.git tags/compiler-attributes-for-linus-v5.4 for you to fetch changes up to 32ee8230b2b06c50f583e14fcd174d7d2edb52f5: x86: bug.h: use asm_inline in _BUG_FLAGS definitions (2019-09-15 20:14:15 +0200) ---------------------------------------------------------------- Make use of gcc 9's "asm inline()" (Rasmus Villemoes): gcc 9+ (and gcc 8.3, 7.5) provides a way to override the otherwise crude heuristic that gcc uses to estimate the size of the code represented by an asm() statement. 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. ---------------------------------------------------------------- Rasmus Villemoes (6): staging: rtl8723bs: replace __inline by inline lib/zstd/mem.h: replace __inline by inline compiler_types.h: don't #define __inline compiler-types.h: add asm_inline definition x86: alternative.h: use asm_inline for all alternative variants x86: bug.h: use asm_inline in _BUG_FLAGS definitions arch/x86/include/asm/alternative.h | 14 +++++++------- arch/x86/include/asm/bug.h | 4 ++-- drivers/staging/rtl8723bs/core/rtw_pwrctrl.c | 4 ++-- drivers/staging/rtl8723bs/core/rtw_wlan_util.c | 2 +- drivers/staging/rtl8723bs/include/drv_types.h | 6 +++--- drivers/staging/rtl8723bs/include/osdep_service.h | 10 +++++----- drivers/staging/rtl8723bs/include/osdep_service_linux.h | 14 +++++++------- drivers/staging/rtl8723bs/include/rtw_mlme.h | 14 +++++++------- drivers/staging/rtl8723bs/include/rtw_recv.h | 16 ++++++++-------- drivers/staging/rtl8723bs/include/sta_info.h | 2 +- drivers/staging/rtl8723bs/include/wifi.h | 14 +++++++------- drivers/staging/rtl8723bs/include/wlan_bssdef.h | 2 +- include/linux/compiler_types.h | 17 ++++++++++++++++- init/Kconfig | 3 +++ lib/zstd/mem.h | 2 +- 15 files changed, 71 insertions(+), 53 deletions(-)
