Changes in v2: - Switch to ALL-$(CONFIG_SYS_THUMB_BUILD) in arch/arm/config.mk (Mike F) - Simplfy checkthumb test after doing the above Signed-off-by: Tom Rini --- Makefile | 7 +++++++ arch/arm/config.mk | 1 + 2 files changed, 8 insertions(+), 0 deletions(-) diff --git a/Makefile b/Makefile index 11aac21..5af4ced 100644 --- a/Makefile +++ b/Makefile @@ -548,6 +548,13 @@ SYSTEM_MAP = \ $(obj)System.map: $(obj)u-boot @$(call SYSTEM_MAP,$<) > $(obj)System.map +checkthumb: + @if test $(call cc-version) -lt 0404; then \ + echo -n '*** Your GCC does not produce working '; \ + echo 'binaries in THUMB mode.'; \ + echo '*** Your board is configured for THUMB mode.'; \ + false; \ + fi # # Auto-generate the autoconf.mk file (which is included by all makefiles) # diff --git a/arch/arm/config.mk b/arch/arm/config.mk index d4fa1f8..367baa2 100644 --- a/arch/arm/config.mk +++ b/arch/arm/config.mk @@ -43,6 +43,7 @@ else PF_CPPFLAGS_ARM := $(call cc-option,-marm,) \ $(call cc-option,-mno-thumb-interwork,) endif +ALL-$(CONFIG_SYS_THUMB_BUILD) += checkthumb # Try if EABI is supported, else fall back to old API, # i. e. for example: -- 1.7.0.4
