[PATCH] ARM: Do not tail-call to an externally-defined function with weak linkage

[Tim Northover]

Hi Oliver,

Is this an armlink work-around? The ABI looks suspiciously like it was written specifically to be compatible with some recalcitrant linker. It's even phrased as a platform-dependent issue (especially so on AArch32).

GNU's linker on Linux (both AArch32 & AArch64) seems to cope fine, for example. So I don't think we'd want to disable the optimisation there. Or anywhere without evidence of problems, really.

Cheers.

Tim.
