Next big-endian targets added are added to GCC RTEMS setup
(the first libraries search subdirecory name and the second GCC
options to select appropriate build mode)
eb
- mbig-endian
- for standard ARMv4
thumb/eb
- mthumb mbig-endian
- for THUMB ARMv4+
thumb/armv7-r/eb
- mthumb march=armv7-r mbig-endian
- for Cortex-R
thumb/armv7-r/fpu/hard/eb
- mthumb march=armv7-r mfpu=vfpv3-d16 mfloat-abi=hard mbig-endian
- for Cortex-R with FPU enabled
and finally hard float target for little-endian ARM Cortex-R which can
be interresting for porting to Ti's RM48 and RM57x and other Cortex-R
little-endian
based chips
thumb/armv7-r/fpu/hard
- mthumb march=armv7-r mfpu=vfpv3-d16 mfloat-abi=hard
- for Cortex-R with FPU enabled
