From a86f516df7931b813bd2524e811e06ad73a2d821 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Gustavsson?= Date: Thu, 23 Sep 2010 14:01:00 +0200 Subject: Use the proper macros in all BIFs As a preparation for changing the calling convention for BIFs, make sure that all BIFs use the macros. Also, eliminate all calls from one BIF to another, since that also breaks the calling convention abstraction. --- erts/emulator/beam/beam_debug.c | 27 +++++--- erts/emulator/beam/beam_emu.c | 12 ++-- erts/emulator/beam/beam_load.c | 13 ++-- erts/emulator/beam/bif.c | 92 +++++++++++++++--------- erts/emulator/beam/break.c | 2 +- erts/emulator/beam/dist.c | 51 ++++++++------ erts/emulator/beam/erl_arith.c | 8 +-- erts/emulator/beam/erl_bif_binary.c | 64 ++++++++++------- erts/emulator/beam/erl_bif_ddll.c | 107 +++++++++++++++------------- erts/emulator/beam/erl_bif_info.c | 64 +++++++++-------- erts/emulator/beam/erl_bif_lists.c | 104 +++++++++++++++------------ erts/emulator/beam/erl_bif_op.c | 25 ++++--- erts/emulator/beam/erl_bif_os.c | 24 ++++--- erts/emulator/beam/erl_bif_port.c | 73 ++++++++++--------- erts/emulator/beam/erl_bif_re.c | 135 ++++++++++++++++++++---------------- erts/emulator/beam/erl_bif_trace.c | 103 ++++++++++++++++++--------- erts/emulator/beam/erl_db.c | 131 ++++++++++++++++++++-------------- erts/emulator/beam/erl_db_tree.c | 10 ++- erts/emulator/beam/erl_db_util.c | 27 +++++--- erts/emulator/beam/erl_db_util.h | 6 +- erts/emulator/beam/erl_monitors.c | 8 ++- erts/emulator/beam/erl_unicode.c | 12 ++-- erts/emulator/beam/external.c | 33 +++++---- erts/emulator/beam/global.h | 6 ++ 24 files changed, 675 insertions(+), 462 deletions(-) (limited to 'erts/emulator/beam') diff --git a/erts/emulator/beam/beam_debug.c b/erts/emulator/beam/beam_debug.c index fffb172c68..18c5081d4c 100644 --- a/erts/emulator/beam/beam_debug.c +++ b/erts/emulator/beam/beam_debug.c @@ -49,15 +49,18 @@ void dbg_bt(Process* p, Eterm* sp);

Change the calling convention for BIFs, so that BIF arguments are passed in an array to the C function implementing the BIF. --- erts/emulator/beam/beam_emu.c | 107 +++++++++++++-------------------------- erts/emulator/beam/bif.h | 16 +++--- erts/emulator/beam/erl_db_util.c | 14 +++-- erts/emulator/beam/erl_trace.c | 13 ++--- erts/emulator/beam/global.h | 3 +- 5 files changed, 59 insertions(+), 94 deletions(-) (limited to 'erts/emulator/beam') diff --git a/erts/emulator/beam/beam_emu.c b/erts/emulator/beam/beam_emu.c index dd4bf6be07..537a94ce29 100644 --- a/erts/emulator/beam/beam_emu.c +++ b/erts/emulator/beam/beam_emu.c @@ -2209,16 +2209,16 @@ void process_main(void) OpCase(bif1_fbsd): { - Eterm (*bf)(Process*, Eterm);
