From db206769c477aae8bafb7ae9b6b4fe1ad56cf729 Mon Sep 17 00:00:00 2001 From: Sverker Eriksson Date: Wed, 23 Jun 2010 16:57:44 +0200 Subject: One off-heap list, to eliminate two words per ETS object. Merging the three off-heap lists (binaries, funs and externals) into one list. This reduces memory consumption by two words (pointers) per ETS object. --- erts/emulator/beam/binary.c | 18 ++++-------------- 1 file changed, 4 insertions(+), 14 deletions(-) (limited to 'erts/emulator/beam/binary.c') diff --git a/erts/emulator/beam/binary.c b/erts/emulator/beam/binary.c index c68392fad4..3fd714f9c2 100644 --- a/erts/emulator/beam/binary.c +++ b/erts/emulator/beam/binary.c @@ -88,8 +88,8 @@ new_binary(Process *p, byte *buf, int len) pb = (ProcBin *) HAlloc(p, PROC_BIN_SIZE); pb->thing_word = HEADER_PROC_BIN; pb->size = len; - pb->next = MSO(p).mso; - MSO(p).mso = pb; + pb->next = MSO(p).first; + MSO(p).first = (struct erl_off_heap_header*)pb; pb->val = bptr; pb->bytes = (byte*) bptr->orig_bytes; pb->flags = 0; @@ -127,8 +127,8 @@ Eterm erts_new_mso_binary(Process *p, byte *buf, int len) pb = (ProcBin *) HAlloc(p, PROC_BIN_SIZE); pb->thing_word = HEADER_PROC_BIN; pb->size = len; - pb->next = MSO(p).mso; - MSO(p).mso = pb; + pb->next = MSO(p).first; + MSO(p).first = (struct erl_off_heap_header*)pb; pb->val = bptr; pb->bytes = (byte*) bptr->orig_bytes; pb->flags = 0; @@ -487,16 +487,6 @@ BIF_RETTYPE split_binary_2(BIF_ALIST_2) BIF_ERROR(BIF_P, BADARG); } -void -erts_cleanup_mso(ProcBin* pb) -{ - while (pb != NULL) { - ProcBin* next = pb->next; - if (erts_refc_dectest(&pb->val->refc, 0) == 0) - erts_bin_free(pb->val); - pb = next; - } -} /* * Local functions. -- cgit v1.2.3
