Change Details

Assembly files in kernel modules append ACFLAGS after CFLAGS. As a result, the hard-float ACFLAGS in bsd.cpu.mk was overriding the soft-float CFLAGS.gcc in sys/conf/kern.mk. In particular, dtrace_asm.o was compiled as hard-float and newer versions of ld.bfd refused to link dtrace.ko since its object files contained a mix of hard and soft float.

ACFLAGS is only used in addition to CFLAGS, so setting the options in both was redundant. However, ACFLAGS is added to the command line after CFLAGS, so the settings from ACFLAGS were applied for assembly files in kernel modules after the kernel-specific march/abi in CFLAGS. As a result, the hard-float ACFLAGS in bsd.cpu.mk was overriding the soft-float CFLAGS.gcc in sys/conf/kern.mk. In particular, dtrace_asm.o was compiled as hard-float and the linker refused to link dtrace.ko since its object files contained a mix of hard and soft float.
