Since the function need to be used from more than one source file, put the function definition in the beam_bp.h header file. Also, give it an 'erts_' prefix since it is globally visible. --- erts/emulator/beam/beam_bp.c | 12 +----------- erts/emulator/beam/beam_bp.h | 17 +++++++++++++++-- erts/emulator/beam/erl_nif.c | 2 +- erts/emulator/beam/utils.c | 1 + 4 files changed, 18 insertions(+), 14 deletions(-) (limited to 'erts/emulator/beam') diff --git a/erts/emulator/beam/beam_bp.c b/erts/emulator/beam/beam_bp.c index dd31376a2d..692fa61fe8 100644 --- a/erts/emulator/beam/beam_bp.c +++ b/erts/emulator/beam/beam_bp.c @@ -495,16 +495,6 @@ erts_find_local_func(Eterm mfa[3]) { return NULL; } -/* bp_hash */ -ERTS_INLINE Uint bp_sched2ix() { -#ifdef ERTS_SMP - ErtsSchedulerData *esdp; - esdp = erts_get_scheduler_data(); - return esdp->no - 1; -#else - return 0; -#endif -} static void bp_hash_init(bp_time_hash_t *hash, Uint n) { Uint size = sizeof(bp_data_time_item_t)*n; Uint i; @@ -1347,7 +1337,7 @@ static BpData *is_break(BeamInstr *pc, BeamInstr break_op) { return NULL; } - bd = ebd = rs[bp_sched2ix()]; + bd = ebd = rs[erts_bp_sched2ix()]; ASSERT(bd); if ( (break_op == 0) || (bd->this_instr == break_op)) { return bd; diff --git a/erts/emulator/beam/beam_bp.h b/erts/emulator/beam/beam_bp.h index 2ec5818688..167069552f 100644 --- a/erts/emulator/beam/beam_bp.h +++ b/erts/emulator/beam/beam_bp.h @@ -144,8 +144,6 @@ extern erts_smp_spinlock_t erts_bp_lock; #define ErtsSmpBPUnlock(BDC) #endif -ERTS_INLINE Uint bp_sched2ix(void); - #ifdef ERTS_SMP #define bp_sched2ix_proc(p) ((p)->scheduler_data->no - 1) #else @@ -247,4 +245,19 @@ BpData *erts_get_time_break(Process *p, BeamInstr *pc); BeamInstr *erts_find_local_func(Eterm mfa[3]); +ERTS_GLB_INLINE Uint erts_bp_sched2ix(void); + +#if ERTS_GLB_INLINE_INCL_FUNC_DEF +ERTS_GLB_INLINE Uint erts_bp_sched2ix(void) +{ +#ifdef ERTS_SMP + ErtsSchedulerData *esdp; + esdp = erts_get_scheduler_data(); + return esdp->no - 1; +#else + return 0; +#endif +} +#endif + #endif /* _BEAM_BP_H */ diff --git a/erts/emulator/beam/erl_nif.c b/erts/emulator/beam/erl_nif.c index 62798bb2c1..740a1b853e 100644 --- a/erts/emulator/beam/erl_nif.c +++ b/erts/emulator/beam/erl_nif.c @@ -1669,7 +1669,7 @@ BIF_RETTYPE load_nif_2(BIF_ALIST_2) } else { /* Function traced, patch the original instruction word */ BpData** bps = (BpData**) code_ptr[1]; - BpData* bp = (BpData*) bps[bp_sched2ix()]; + BpData* bp = (BpData*) bps[erts_bp_sched2ix()]; bp->orig_instr = (BeamInstr) BeamOp(op_call_nif); } code_ptr[5+1] = (BeamInstr) entry->funcs[i].fptr; diff --git a/erts/emulator/beam/utils.c b/erts/emulator/beam/utils.c index e4ad7dcb24..7c3de9da42 100644 --- a/erts/emulator/beam/utils.c +++ b/erts/emulator/beam/utils.c @@ -45,6 +45,7 @@ #include "erl_thr_progress.h" #include "erl_thr_queue.h" #include "erl_sched_spec_pre_alloc.h" +#include "beam_bp.h" #undef M_TRIM_THRESHOLD #undef M_TOP_PAD -- cgit v1.2.3
