With GCC 3.4 and also the hammer-branch of GCC 3.3, unit-at-a-time compilation is enabled and rearranges the output order of functions. This is not desirable in some cases. Here's the patch that we're currently using at SuSE. Ok to commit? Andreas 2003-11-30 Andreas Jaeger <aj@suse.de> * csu/Makefile (CFLAGS-initfini.s): Add -fno-unit-at-a-time. * linuxthreads/sysdeps/unix/sysv/linux/x86_64/Makefile (CFLAGS-pt-initfini.s): Likewise. * locale/Makefile (CFLAGS-loadlocale.c): Likewise. For linuxthreads: * Makefile (CFLAGS-tst-cancel.c): Add -fno-unit-at-a-time. (CFLAGS-pt-initfini.s): Likewise. For nptl: * Makefile (CFLAGS-pt-initfini.s): Add -fno-unit-at-a-time. ============================================================ Index: csu/Makefile --- csu/Makefile 26 Jun 2003 07:27:39 -0000 1.70 +++ csu/Makefile 18 Jul 2003 05:27:14 -0000 @@ -104,7 +104,7 @@ omit-deps += $(crtstuff) $(crtstuff:%=$(objpfx)%.o): %.o: %.S $(objpfx)defs.h $(compile.S) -g0 $(ASFLAGS-.os) -o $@ -CFLAGS-initfini.s = -g0 -fPIC -fno-inline-functions +CFLAGS-initfini.s = -g0 -fPIC -fno-inline-functions -fno-unit-at-a-time vpath initfini.c $(full_config_sysdirs) ============================================================ Index: linuxthreads/sysdeps/unix/sysv/linux/x86_64/Makefile --- linuxthreads/sysdeps/unix/sysv/linux/x86_64/Makefile 11 Apr 2003 23:34:02 -0000 1.5 +++ linuxthreads/sysdeps/unix/sysv/linux/x86_64/Makefile 18 Jul 2003 05:27:14 -0000 @@ -1,3 +1,3 @@ ifeq ($(subdir),linuxthreads) -CFLAGS-pt-initfini.s = -g0 -fPIC -fno-inline-functions -fno-asynchronous-unwind-tables +CFLAGS-pt-initfini.s = -g0 -fPIC -fno-inline-functions -fno-asynchronous-unwind-tables -fno-unit-at-a-time endif ============================================================ Index: linuxthreads/Makefile --- linuxthreads/Makefile 10 Jun 2003 02:19:43 -0000 1.77 +++ linuxthreads/Makefile 18 Jul 2003 05:27:14 -0000 @@ -66,7 +66,7 @@ LDFLAGS-pthread.so = $(nodelete-$(have-z vpath %.c Examples tst-cancel-ARGS = "$(objpfx)" -CFLAGS-tst-cancel.c = -fno-inline -fno-inline-functions +CFLAGS-tst-cancel.c = -fno-inline -fno-inline-functions -fno-unit-at-a-time include ../Makeconfig @@ -99,7 +99,7 @@ endif extra-objs += $(crti-objs) $(crtn-objs) omit-deps += crti crtn -CFLAGS-pt-initfini.s = -g0 -fPIC -fno-inline-functions +CFLAGS-pt-initfini.s = -g0 -fPIC -fno-inline-functions -fno-unit-at-a-time endif librt-tests = ex10 ex11 ============================================================ Index: locale/Makefile --- locale/Makefile 13 Jun 2003 20:42:48 -0000 1.71 +++ locale/Makefile 28 Jul 2003 10:45:07 -0000 @@ -100,6 +100,7 @@ locale-CPPFLAGS := -DLOCALE_PATH='$(loca CFLAGS-charmap.c = -Wno-write-strings -Wno-char-subscripts CFLAGS-locfile.c = -Wno-write-strings -Wno-char-subscripts CFLAGS-charmap-dir.c = -Wno-write-strings +CFLAGS-loadlocale.c = -fno-unit-at-a-time # This makes sure -DNOT_IN_libc is passed for all these modules. cpp-srcs-left := $(addsuffix .c,$(localedef-modules) $(localedef-aux) \ --- nptl/Makefile 6 Nov 2003 09:47:37 -0000 1.124 +++ nptl/Makefile 18 Nov 2003 20:30:23 -0000 @@ -312,7 +312,7 @@ extra-objs += $(crti-objs) $(crtn-objs) omit-deps += crti crtn -CFLAGS-pt-initfini.s = -g0 -fPIC -fno-inline-functions +CFLAGS-pt-initfini.s = -g0 -fPIC -fno-inline-functions -fno-unit-at-a-time endif CFLAGS-flockfile.c = -D_IO_MTSAFE_IO --- nptl/sysdeps/unix/sysv/linux/x86_64/Makefile 9 May 2003 07:29:09 -0000 1.3 +++ nptl/sysdeps/unix/sysv/linux/x86_64/Makefile 18 Nov 2003 20:30:23 -0000 @@ -1,3 +1,3 @@ ifeq ($(subdir),nptl) -CFLAGS-pt-initfini.s = -g0 -fPIC -fno-inline-functions -fno-asynchronous-unwind-tables +CFLAGS-pt-initfini.s = -g0 -fPIC -fno-inline-functions -fno-asynchronous-unwind-tables -fno-unit-at-a-time endif -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SuSE Linux AG, Deutschherrnstr. 15-19, 90429 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126
