From 0a2988d3a1a42f18e18ab00b940a0c12b2031ba1 Mon Sep 17 00:00:00 2001 From: Lukas Larsson Date: Mon, 17 Dec 2018 12:25:32 +0100 Subject: erts: Remove dead ERTS_MAGIC_REF_BIF_TIMERS code Using magic refs for big timers caused too large a stress on the off_heap GC implementation to be viable, so it was never enable. The code is now broken because of other changes to we might as well remove it. --- erts/emulator/beam/erl_hl_timer.c | 377 +------------------------------------- 1 file changed, 10 insertions(+), 367 deletions(-) (limited to 'erts') diff --git a/erts/emulator/beam/erl_hl_timer.c b/erts/emulator/beam/erl_hl_timer.c index ef7a55fa38..c476d2b74f 100644 --- a/erts/emulator/beam/erl_hl_timer.c +++ b/erts/emulator/beam/erl_hl_timer.c @@ -29,8 +29,6 @@ # include "config.h" #endif -/* #define ERTS_MAGIC_REF_BIF_TIMERS */ - #include "sys.h" #include "global.h" #include "bif.h" @@ -39,9 +37,6 @@ #include "erl_time.h" #include "erl_hl_timer.h" #include "erl_proc_sig_queue.h" -#ifdef ERTS_MAGIC_REF_BIF_TIMERS -#include "erl_binary.h" -#endif #define ERTS_TMR_CHECK_CANCEL_ON_CREATE 0 @@ -195,14 +190,9 @@ struct ErtsBifTimer_ { } type;
