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/break.c | 32 ++++++++++++++++---------------- 1 file changed, 16 insertions(+), 16 deletions(-) (limited to 'erts/emulator/beam/break.c') diff --git a/erts/emulator/beam/break.c b/erts/emulator/beam/break.c index 857cb177c8..f339e19761 100644 --- a/erts/emulator/beam/break.c +++ b/erts/emulator/beam/break.c @@ -611,29 +611,29 @@ static void bin_check(void) { Process *rp; - ProcBin *bp; - int i, printed; + struct erl_off_heap_header* hdr; + int i, printed = 0; for (i=0; i < erts_max_processes; i++) { if ((rp = process_tab[i]) == NULL) continue; - if (!(bp = rp->off_heap.mso)) - continue; - printed = 0; - while (bp) { - if (printed == 0) { - erts_printf("Process %T holding binary data \n", rp->id); - printed = 1; + for (hdr = rp->off_heap.first; hdr; hdr = hdr->next) { + if (hdr->thing_word == HEADER_PROC_BIN) { + ProcBin *bp = (ProcBin*) hdr; + if (!printed) { + erts_printf("Process %T holding binary data \n", rp->id); + printed = 1; + } + erts_printf("0x%08lx orig_size: %ld, norefs = %ld\n", + (unsigned long)bp->val, + (long)bp->val->orig_size, + erts_smp_atomic_read(&bp->val->refc)); } - erts_printf("0x%08lx orig_size: %ld, norefs = %ld\n", - (unsigned long)bp->val, - (long)bp->val->orig_size, - erts_smp_atomic_read(&bp->val->refc)); - - bp = bp->next; } - if (printed == 1) + if (printed) { erts_printf("--------------------------------------\n"); + printed = 0; + } } /* db_bin_check() has to be rewritten for the AVL trees... */ /*db_bin_check();*/ -- cgit v1.2.3
