This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "uClibc-ng - small C library for embedded systems". The branch, upstream has been updated via a1b88fe87a9d2be5696247d266f5c4fd20f000bb (commit) via a58f1e2a537d339bf4d37058b4cc4324b24c569f (commit) from b36422960466777495933ed1eb50befd1c34e9a9 (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- commit a1b88fe87a9d2be5696247d266f5c4fd20f000bb Author: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> Date: Wed Dec 3 17:43:25 2014 +0100 mips: rename siginfo _timer members Rename _timer[12] to si_tid and si_overrun to fix compilation of strace-4.9+ Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> commit a58f1e2a537d339bf4d37058b4cc4324b24c569f Author: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> Date: Wed Dec 3 16:18:54 2014 +0100 buildsys: remove some obsolete optimization CFLAGS Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> ----------------------------------------------------------------------- Summary of changes: Rules.mak | 36 ++++++++-------------- libc/sysdeps/linux/mips/bits/siginfo.h | 51 +++++++++++++++++++++----------- 2 files changed, 45 insertions(+), 42 deletions(-) diff --git a/Rules.mak b/Rules.mak index 2121ada..202f31f 100644 --- a/Rules.mak +++ b/Rules.mak @@ -260,9 +260,17 @@ LDFLAG-fuse-ld := $(filter -fuse-ld=%,$(call qstrip,$(UCLIBC_EXTRA_CFLAGS))) # Could use -Wl,--script,$(top_srcdir)extra/scripts/none.lds as well. $(eval $(call check-ld-var,--no-warn-mismatch)) +$(eval $(call cache-output-var,GCC_VER,$(CC) -dumpversion)) +GCC_VER := $(subst ., ,$(GCC_VER)) +GCC_MAJOR_VER ?= $(word 1,$(GCC_VER)) +GCC_MINOR_VER ?= $(word 2,$(GCC_VER)) + # Flags in OPTIMIZATION are used only for non-debug builds OPTIMIZATION:= +OPTIMIZATION-$(GCC_MAJOR_VER):= +OPTIMIZATION-$(GCC_MAJOR_VER).$(GCC_MINOR_VER):= + # Use '-Os' optimization if available, else use -O2, allow Config to override $(eval $(call check-gcc-var,-Os)) ifneq ($(CFLAG_-Os),) @@ -273,31 +281,9 @@ OPTIMIZATION += $(CFLAG_-O2) endif # Use the gcc 3.4 -funit-at-a-time optimization when available $(eval $(call check-gcc-var,-funit-at-a-time)) -OPTIMIZATION += $(CFLAG_-funit-at-a-time) -# shrinks code by about 0.1% -$(eval $(call check-gcc-var,-fmerge-all-constants)) +OPTIMIZATION-3.4 += $(CFLAG_-funit-at-a-time) $(eval $(call check-gcc-var,-fstrict-aliasing)) -OPTIMIZATION += $(CFLAG_-fmerge-all-constants) $(CFLAG_-fstrict-aliasing) - -$(eval $(call cache-output-var,GCC_VER,$(CC) -dumpversion)) -GCC_VER := $(subst ., ,$(GCC_VER)) -GCC_MAJOR_VER ?= $(word 1,$(GCC_VER)) -#GCC_MINOR_VER ?= $(word 2,$(GCC_VER)) - -ifneq ($(TARGET_ARCH),arc) -ifeq ($(GCC_MAJOR_VER),4) -# shrinks code, results are from 4.0.2 -# 0.36% -$(eval $(call check-gcc-var,-fno-tree-loop-optimize)) -OPTIMIZATION += $(CFLAG_-fno-tree-loop-optimize) -# 0.34% -$(eval $(call check-gcc-var,-fno-tree-dominator-opts)) -OPTIMIZATION += $(CFLAG_-fno-tree-dominator-opts) -# 0.1% -$(eval $(call check-gcc-var,-fno-strength-reduce)) -OPTIMIZATION += $(CFLAG_-fno-strength-reduce) -endif -endif +OPTIMIZATION += $(CFLAG_-fstrict-aliasing) # CPU_CFLAGS-y contain options which are not warnings, # not include or library paths, and not optimizations. @@ -707,6 +693,8 @@ ifeq ($(DODEBUG),y) CFLAGS += -O0 -g3 -DDEBUG else CFLAGS += $(OPTIMIZATION) +CFLAGS += $(OPTIMIZATION-$(GCC_MAJOR_VER)) +CFLAGS += $(OPTIMIZATION-$(GCC_MAJOR_VER).$(GCC_MINOR_VER)) endif ifeq ($(DOSTRIP),y) LDFLAGS += -Wl,-s diff --git a/libc/sysdeps/linux/mips/bits/siginfo.h b/libc/sysdeps/linux/mips/bits/siginfo.h index a6e4135..5199d4d 100644 --- a/libc/sysdeps/linux/mips/bits/siginfo.h +++ b/libc/sysdeps/linux/mips/bits/siginfo.h @@ -69,6 +69,22 @@ typedef struct siginfo __uid_t si_uid;
