[PATCH] [lld][ARM] Add relocations to perform function calls

[Denis Protivensky]

Shankar,

In general case - you're right, the stub is needed to interwork between ARM and Thumb code.
The current implementation covers a subset of the interwork where non-conditional jumps of B/BL forms are used, and they are fixed by changing to BLX instructions (works for ARMv5 and above).

Stub generation should be determined and done in the relocation pass, and it doesn't deny currently implemented instruction fixups, but supplements them.
I'm currently working on the stub generation, but I'd like this part of work with instruction fixups to be accepted. Is it ok?
