From fc0477a67641b9ba344de595b7fec2431208f8e6 Mon Sep 17 00:00:00 2001 From: Rickard Green Date: Tue, 24 Jan 2017 19:50:25 +0100 Subject: Atomic reference count of binaries also in non-SMP NIF resources was not handled in a thread-safe manner in the runtime system without SMP support. As a consequence of this fix, the following driver functions are now thread-safe also in the runtime system without SMP support: - driver_free_binary() - driver_realloc_binary() - driver_binary_get_refc() - driver_binary_inc_refc() - driver_binary_dec_refc() --- erts/emulator/hipe/hipe_bif0.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'erts/emulator/hipe/hipe_bif0.c') diff --git a/erts/emulator/hipe/hipe_bif0.c b/erts/emulator/hipe/hipe_bif0.c index dcb6c35bfa..165f33eecd 100644 --- a/erts/emulator/hipe/hipe_bif0.c +++ b/erts/emulator/hipe/hipe_bif0.c @@ -992,7 +992,7 @@ BIF_RETTYPE hipe_bifs_set_native_address_in_fe_2(BIF_ALIST_2) BIF_ERROR(BIF_P, BADARG); fe->native_address = native_address; - if (erts_refc_dectest(&fe->refc, 0) == 0) + if (erts_smp_refc_dectest(&fe->refc, 0) == 0) erts_erase_fun_entry(fe); BIF_RET(am_true); } -- cgit v1.2.3
