910 We should really create new local (static) symbols in destination
911 object for each stub we create. We should also create local
912 (static) symbols within the stubs when switching between ARM and
913 Thumb code. This will ensure that the debugger and disassembler
914 can present a better view of stubs.
916 We can treat stubs like literal sections, and for the THUMB9 ones
917 (short addressing range) we should be able to insert the stubs
918 between sections. i.e. the simplest approach (since relocations
919 are done on a section basis) is to dump the stubs at the end of
920 processing a section. That way we can always try and minimise the
921 offset to and from a stub. However, this does not map well onto
922 the way that the linker/BFD does its work: mapping all input
923 sections to output sections via the linker script before doing
926 Unfortunately it may be easier to just to disallow short range
927 Thumb->ARM stubs (i.e. no conditional inter-working branches,
928 only branch-and-link (BL) calls. This will simplify the processing
929 since we can then put all of the stubs into their own section.
932 On a different subject, rather than complaining when a
933 branch cannot fit in the number of bits available for the
934 instruction we should generate a trampoline stub (needed to
935 address the complete 32bit address space). */
