From 855b3a9be724ffd3c9f7e311cf9d810099fa36ef Mon Sep 17 00:00:00 2001 From: Lukas Larsson Date: Mon, 27 Jun 2016 20:18:22 +0200 Subject: erts: Refactor out func_info into struct This commit adds two new structs to be used to represent erlang code in erts. ErtsCodeInfo is used to describe the i_func_info header that is part of all Export entries and the prelude of each function. This replaces all the BeamInstr * that were previously used to point to these locations. After this change the code should never use BeamInstr * with offsets to figure out different parts of the func_info header. ErtsCodeMFA is a struct that is used to descripe a MFA in code. It is used within ErtsCodeInfo and also in Process->current. All function that previously took Eterm * or BeamInstr * to identify a MFA now use the ErtsCodeMFA or ErtsCodeInfo where appropriate. The code has been tested to work when adding a new field to the ErtsCodeInfo struct, but some updates are needed in ops.tab to make it work. --- erts/emulator/beam/erl_printf_term.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'erts/emulator/beam/erl_printf_term.c') diff --git a/erts/emulator/beam/erl_printf_term.c b/erts/emulator/beam/erl_printf_term.c index 1a579704a8..b43a1b0190 100644 --- a/erts/emulator/beam/erl_printf_term.c +++ b/erts/emulator/beam/erl_printf_term.c @@ -526,8 +526,8 @@ print_term(fmtfn_t fn, void* arg, Eterm obj, long *dcount) { case EXPORT_DEF: { Export* ep = *((Export **) (export_val(wobj) + 1)); - Atom* module = atom_tab(atom_val(ep->code[0])); - Atom* name = atom_tab(atom_val(ep->code[1])); + Atom* module = atom_tab(atom_val(ep->info.mfa.module)); + Atom* name = atom_tab(atom_val(ep->info.mfa.function)); PRINT_STRING(res, fn, arg, "#Fun<"); PRINT_BUF(res, fn, arg, module->name, module->len); @@ -535,7 +535,7 @@ print_term(fmtfn_t fn, void* arg, Eterm obj, long *dcount) { PRINT_BUF(res, fn, arg, name->name, name->len); PRINT_CHAR(res, fn, arg, '.'); PRINT_SWORD(res, fn, arg, 'd', 0, 1, - (ErlPfSWord) ep->code[2]); + (ErlPfSWord) ep->info.mfa.arity); PRINT_CHAR(res, fn, arg, '>'); } break; -- cgit v1.2.3
