GCC for Debian's "powerpcspe" architecture only supports 32-bit SPE targets, and using -mcpu=powerpc or -mcpu=powerpc64 is a fatal error.
* Change the test for a biarch compiler to pass both the -m32 and -m64 options, so that it doesn't catch 32-bit-only compilers * Add an ifdef CONFIG_PPC64 around the 64-bit CPU option definitions Signed-off-by: Ben Hutchings <b...@decadent.org.uk> --- arch/powerpc/Makefile | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/arch/powerpc/Makefile b/arch/powerpc/Makefile index 488c9edffa58..c2e815863500 100644 --- a/arch/powerpc/Makefile +++ b/arch/powerpc/Makefile @@ -12,7 +12,7 @@ # Rewritten by Cort Dougan and Paul Mackerras # -HAS_BIARCH := $(call cc-option-yn, -m32) +HAS_BIARCH := $(call cc-option-yn, -m32 -m64) # Set default 32 bits cross compilers for vdso and boot wrapper CROSS32_COMPILE ?= @@ -166,6 +166,7 @@ CFLAGS-$(CONFIG_PPC32) += $(call cc-option, $(MULTIPLEWORD)) CFLAGS-$(CONFIG_PPC32) += $(call cc-option,-mno-readonly-in-sdata) +ifdef CONFIG_PPC64 ifdef CONFIG_PPC_BOOK3S_64 ifdef CONFIG_CPU_LITTLE_ENDIAN CFLAGS-$(CONFIG_GENERIC_CPU) += -mcpu=power8 @@ -177,6 +178,7 @@ endif else CFLAGS-$(CONFIG_GENERIC_CPU) += -mcpu=powerpc64 endif +endif ifdef CONFIG_FUNCTION_TRACER CC_FLAGS_FTRACE := -pg
