3ARM_INSTRUCTION_SET ?= "arm"
4# "arm" "thumb"
5# The instruction set the compiler should use when generating application
6# code. The kernel is always compiled with arm code at present. arm code
7# is the original 32 bit ARM instruction set, thumb code is the 16 bit
8# encoded RISC sub-set. Thumb code is smaller (maybe 70% of the ARM size)
9# but requires more instructions (140% for 70% smaller code) so may be
10# slower.

12THUMB_INTERWORK ?= "yes"
13# "yes" "no"
14# Whether to compile with code to allow interworking between the two
15# instruction sets. This allows thumb code to be executed on a primarily
16# arm system and vice versa. It is strongly recommended that DISTROs not
17# turn this off - the actual cost is very small.
