From 099c60de4033d7b397d4b3fb47f183b52fcba855 Mon Sep 17 00:00:00 2001 From: Sverker Eriksson Date: Thu, 15 Sep 2016 21:21:10 +0200 Subject: erts: Improve hipe load/upgrade/purge machinery A step toward better integration of hipe load and purge Highlights: * code_server no longer needs to call hipe_unified_loader:post_beam_load/1 Instead new internal function hipe_redirect_to_module() is called by loading BIFs to patch native call sites if needed. * hipe_purge_module() is called by erts_internal:purge_module/2 to purge any native code. * struct hipe_mfa_info redesigned and only used for exported functions that are called from or implemented by native code. A list of native call sites (struct hipe_ref) are kept for each hipe_mfa_info. * struct hipe_sdesc used by hipe_find_mfa_from_ra() to build native stack traces. --- erts/emulator/hipe/hipe_amd64.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'erts/emulator/hipe/hipe_amd64.c') diff --git a/erts/emulator/hipe/hipe_amd64.c b/erts/emulator/hipe/hipe_amd64.c index 62739d2a78..df53f4db30 100644 --- a/erts/emulator/hipe/hipe_amd64.c +++ b/erts/emulator/hipe/hipe_amd64.c @@ -130,6 +130,13 @@ void *hipe_alloc_code(Uint nrbytes, Eterm callees, Eterm *trampolines, Process * return alloc_code(nrbytes); } +void hipe_free_code(void* code) +{ + ALLOC_CODE_STATS(--nr_allocs); + /*ALLOC_CODE_STATS(total_alloc += alloc_bytes);*/ + erts_free(ERTS_ALC_T_HIPE_EXEC, code); +} + /* Make stub for native code calling exported beam function. */ void *hipe_make_native_stub(void *callee_exp, unsigned int beamArity) @@ -234,6 +241,14 @@ void *hipe_make_native_stub(void *callee_exp, unsigned int beamArity) return code; } +void hipe_free_native_stub(void* stub) +{ + ALLOC_CODE_STATS(++nr_allocs); + /*ALLOC_CODE_STATS(total_alloc += alloc_bytes);*/ + + erts_free(ERTS_ALC_T_HIPE_EXEC, stub); +} + void hipe_arch_print_pcb(struct hipe_process_state *p) { #define U(n,x) \ -- cgit v1.2.3
