Add three new blind options to set use of Thumb mode:
|
|
- COMPILE_IN_THUMB_MODE
|
|
- if set, CFLAGS will contain -mthumb
|
|
- if unset, the compiler's default is used
|
|
- HAS_THUMB
|
|
- CPUS with Thumb instruction set can select this
|
|
- use of BX depends on this
|
|
- FORCE_THUMB
|
|
- CPUs that are Thumb-only must select this
|
|
- this selects: HAS_THUMB, COMPILE_IN_THUMB_MODE and USE_BX
|
|
|
|
Also, remove leading space in Rules.mak.
