From 5a8e6c4183a30f3b10de22fa5ba80950dfb2adea Mon Sep 17 00:00:00 2001 From: Patrik Nyblom Date: Mon, 7 Dec 2009 15:25:32 +0100 Subject: Fit all heap data into the 32-bit address range This is the first step in the implementation of the half-word emulator, a 64-bit emulator where all pointers to heap data will be stored in 32-bit words. Code specific for this emulator variant is conditionally compiled when the HALFWORD_HEAP define has a non-zero value. First force all pointers to heap data to fall into a single 32-bit range, but still store them in 64-bit words. Temporary term data stored on C stack is moved into scheduler specific storage (allocated as heaps) and macros are added to make this happen only in emulators where this is needed. For a vanilla VM the temporary terms are still stored on the C stack. --- erts/emulator/beam/erl_lock_check.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'erts/emulator/beam/erl_lock_check.c') diff --git a/erts/emulator/beam/erl_lock_check.c b/erts/emulator/beam/erl_lock_check.c index 074b08ea57..4858be1b75 100644 --- a/erts/emulator/beam/erl_lock_check.c +++ b/erts/emulator/beam/erl_lock_check.c @@ -1231,6 +1231,8 @@ void erts_lc_init_lock(erts_lc_lock_t *lck, char *name, Uint16 flags) { lck->id = erts_lc_get_lock_order_id(name); + + /* XXX:PaN What to do with the extra information? */ lck->extra = make_boxed(&lck->extra); lck->flags = flags; lck->inited = ERTS_LC_INITITALIZED; -- cgit v1.2.3
