However, when the ErLLVM HiPE backend is used, LLVM may choose to perform tailcall optimisation on these calls, breaking the expected semantics. To preserve the precise semantics exhibited by BEAM, the 'notail' marker, present in LLVM since version 3.8, is added to call instructions that BEAM has not turned into tail calls, which inhibits LLVM from performing tail-call optimisation in turn. --- lib/hipe/llvm/hipe_llvm.erl | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/hipe/llvm/hipe_llvm.erl b/lib/hipe/llvm/hipe_llvm.erl index 641d3fda0a..e04b171194 100644 --- a/lib/hipe/llvm/hipe_llvm.erl +++ b/lib/hipe/llvm/hipe_llvm.erl @@ -934,7 +934,7 @@ pp_ins(Dev, Ver, I) -> end, case call_is_tail(I) of true -> write(Dev, "tail "); - false -> ok + false -> write(Dev, "notail ") end, write(Dev, ["call ", call_cconv(I), " "]), pp_options(Dev, call_ret_attrs(I)), -- cgit v1.2.3
