The build system implementation of multilib layout is very generic and allows +complete customisation of the library directories. + +This patch is a partial solution to allow any custom directories to be passed into gcc +and handled correctly. It forces gcc to use the base_libdir (which is the current +directory, "."). We need to do this for each multilib that is configured as we don't +know which compiler options may be being passed into the compiler. Since we have a compiler +per mulitlib at this point that isn't an issue. + +The one problem is the target compiler is only going to work for the default multlilib at +this point. Ideally we'd figure out which multilibs were being enabled with which paths +and be able to patch these entries with a complete set of correct paths but this we +don't have such code at this point. This is something the target gcc recipe should do +and override these platform defaults in its build config. + +RP 15/8/11 + +Signed-off-by: Khem Raj <raj.khem@gmail.com> +Signed-off-by: Elvis Dowson <elvis.dowson@gmail.com> + +Upstream-Status: Pending +--- + gcc/config/i386/t-linux64 | 6 ++---- + gcc/config/mips/t-linux64 | 10 +++------- + gcc/config/rs6000/t-linux64 | 5 ++--- + 3 files changed, 7 insertions(+), 14 deletions(-) + +diff --git a/gcc/config/i386/t-linux64 b/gcc/config/i386/t-linux64 +index f6dbb78..d770da5 100644 +--- a/gcc/config/i386/t-linux64 ++++ b/gcc/config/i386/t-linux64 +@@ -32,7 +32,5 @@ + # + comma=, + MULTILIB_OPTIONS = $(subst $(comma),/,$(TM_MULTILIB_CONFIG)) +-MULTILIB_DIRNAMES = $(patsubst m%, %, $(subst /, ,$(MULTILIB_OPTIONS))) +-MULTILIB_OSDIRNAMES = m64=../lib64$(call if_multiarch,:x86_64-linux-gnu) +-MULTILIB_OSDIRNAMES+= m32=$(if $(wildcard $(shell echo $(SYSTEM_HEADER_DIR))/../../usr/lib32),../lib32,../lib)$(call if_multiarch,:i386-linux-gnu) +-MULTILIB_OSDIRNAMES+= mx32=../libx32$(call if_multiarch,:x86_64-linux-gnux32) ++MULTILIB_DIRNAMES = . . ++MULTILIB_OSDIRNAMES = ../$(shell basename $(base_libdir)) ../$(shell basename $(base_libdir)) +diff --git a/gcc/config/mips/t-linux64 b/gcc/config/mips/t-linux64 +index 7e96406..b72dcb0 100644 +--- a/gcc/config/mips/t-linux64 ++++ b/gcc/config/mips/t-linux64 +@@ -17,10 +17,6 @@ + # <http://www.gnu.org/licenses/>. + + MULTILIB_OPTIONS = mabi=n32/mabi=32/mabi=64 +-MULTILIB_DIRNAMES = n32 32 64 +-MIPS_EL = $(if $(filter %el, $(firstword $(subst -, ,$(target)))),el) +-MIPS_SOFT = $(if $(strip $(filter MASK_SOFT_FLOAT_ABI, $(target_cpu_default)) $(filter soft, $(with_float))),soft) +-MULTILIB_OSDIRNAMES = \ +- ../lib32$(call if_multiarch,:mips64$(MIPS_EL)-linux-gnuabin32$(MIPS_SOFT)) \ +- ../lib$(call if_multiarch,:mips$(MIPS_EL)-linux-gnu$(MIPS_SOFT)) \ +- ../lib64$(call if_multiarch,:mips64$(MIPS_EL)-linux-gnuabi64$(MIPS_SOFT)) ++MULTILIB_DIRNAMES = . . . ++MULTILIB_OSDIRNAMES = ../$(shell basename $(base_libdir)) ../$(shell basename $(base_libdir)) ../$(shell basename $(base_libdir)) ++ +diff --git a/gcc/config/rs6000/t-linux64 b/gcc/config/rs6000/t-linux64 +index b6b351d..1d5b37a 100644 +--- a/gcc/config/rs6000/t-linux64 ++++ b/gcc/config/rs6000/t-linux64 +@@ -26,10 +26,9 @@ + # MULTILIB_OSDIRNAMES according to what is found on the target. + + MULTILIB_OPTIONS := m64/m32 +-MULTILIB_DIRNAMES := 64 32 ++MULTILIB_DIRNAMES := . . + MULTILIB_EXTRA_OPTS := +-MULTILIB_OSDIRNAMES := m64=../lib64$(call if_multiarch,:powerpc64-linux-gnu) +-MULTILIB_OSDIRNAMES += m32=$(if $(wildcard $(shell echo $(SYSTEM_HEADER_DIR))/../../usr/lib32),../lib32,../lib)$(call if_multiarch,:powerpc-linux-gnu) ++MULTILIB_OSDIRNAMES := ../$(shell basename $(base_libdir)) ../$(shell basename $(base_libdir)) + + rs6000-linux.o: $(srcdir)/config/rs6000/rs6000-linux.c + $(COMPILE) $< +-- +2.6.3 + |
