GCCJIT and tail-recursive calls

[Basile Starynkevitch <basile@starynkevitch.net>]

Hello all,

It is well known that GCC is sometimes able to optimize some calls to 
tail-recursive calls (or tail calls
https://en.wikipedia.org/wiki/Tail_call ...) which do not consume any stack.

can a GCCJIT application issues such tail calls? I'm not talking of 
letting GCC decide entirely by itself (GCCJIT is probably doing that 
already). I was thinking of adding a construct where the GCCJIT client knows
for sure that the call should be tail-rec (and if GCCJIT was not able to 
make a tailcall, that would be an error).
Also, even without optimization (i.e. at -O0) that should remain a 
tailcall...

Perhaps adding a gcc_jit_block_end_with_tail_call function?

Regards.
