#tune file for thumb instructions
ARM_INSTRUCTION_SET ?= "arm"
# "arm" "thumb"
# The instruction set the compiler should use when generating application
# code. The kernel is always compiled with arm code at present. arm code
# is the original 32 bit ARM instruction set, thumb code is the 16 bit
# encoded RISC sub-set. Thumb code is smaller (maybe 70% of the ARM size)
# but requires more instructions (140% for 70% smaller code) so may be
# slower.
THUMB_INTERWORK ?= "yes"
# "yes" "no"
# Whether to compile with code to allow interworking between the two
# instruction sets. This allows thumb code to be executed on a primarily
# arm system and vice versa. It is strongly recommended that DISTROs not
# turn this off - the actual cost is very small.

# instruction set and interworking.
