C++ allows multiple ways of # expressing this. # # struct ... { private: ... }; # class ... { private: ... }; # class ... { ... }; # # RE_VBPTR matches the virtual base declarations. gcc 2.95.3 sometimes # emits these, but gcc 3.X.Y never emits these. The name depends on the # debug format. # # RE_FIELDS matches the data fields of the class. # RE_METHODS matches the methods explicitly declared for the class. # # RE_SYNTH_GCC_2 and RE_SYNTH_GCC_3 match the optional synthetic methods # of the class. gcc -gstabs+ emits these methods, and gcc -gdwarf-2 # does not. # # RE_ACCESS_METHODS is an access specifier after RE_FIELDS and before # the methods (explicit methods and/or synthetic methods). # There is also an RE_ACCESS_FIELDS. # # When I get HP-UX aCC, I hope that I can just add RE_SYNTH_ACC_NNN. # # Yet another twist: with gcc v2, ctor and dtor methods have a hidden # argument in front, the "in-charge" flag. With gcc v3, there is no # hidden argument; instead, there are multiple object functions for # each ctor and dtor. # # -- chastain 2004-01-01 proc test_one_ptype { command testname re_class re_vbptr re_access_fields re_fields re_access_methods re_methods re_synth_gcc_2 re_synth_gcc_3 re_star } { global gdb_prompt global wsopt global ws global nl gdb_test_multiple "$command" "$testname" { -re "type = $re_class${wsopt}$re_access_fields${wsopt}$re_fields${wsopt}$re_access_methods${wsopt}$re_methods$nl\}$re_star$nl$gdb_prompt $" { # gcc 2.95.3, dwarf-2, no vbptr # gcc 3.X, abi 1, dwarf-2 # gcc 3.X, abi 2, dwarf-2 pass "$testname" } -re "type = $re_class${wsopt}$re_vbptr${wsopt}$re_access_fields${wsopt}$re_fields${wsopt}$re_access_methods${wsopt}$re_methods$nl\}$re_star$nl$gdb_prompt $" { # gcc 2.95.3, dwarf-2, vbptr # TODO: drow says the vbptr is a bug pass "$testname" } -re "type = $re_class${wsopt}$re_access_fields${wsopt}$re_fields${wsopt}$re_access_methods${wsopt}$re_synth_gcc_2${wsopt}$re_methods$nl\}$re_star$nl$gdb_prompt $" { # gcc 2.95.3, stabs+, no vbptr pass "$testname" } -re "type = $re_class${wsopt}$re_vbptr${wsopt}$re_access_fields${wsopt}$re_fields${wsopt}$re_access_methods${wsopt}$re_synth_gcc_2${wsopt}$re_methods$nl\}$re_star$nl$gdb_prompt $" { # gcc 2.95.3, stabs+, vbptr # TODO: drow says the vbptr is a bug pass "$testname" } -re "type = $re_class${wsopt}$re_access_fields${wsopt}$re_fields${wsopt}$re_access_methods${wsopt}$re_synth_gcc_3${wsopt}$re_methods$nl\}$re_star$nl$gdb_prompt $" { # gcc 3.X, abi 1, stabs+ pass "$testname" } -re "type = $re_class${wsopt}$re_access_fields${wsopt}$re_fields${wsopt}$re_access_methods${wsopt}$re_methods${wsopt}$re_synth_gcc_3$nl\}$re_star$nl$gdb_prompt $" { # gcc 3.X, abi 2, stabs+ pass "$testname" } } } proc test_ptype_of_classes {} { global gdb_prompt global ws global nl # class VA test_one_ptype "ptype VA" "ptype VA" \ "((struct|class) VA \{${ws}public:|struct VA \{)" \ "" \ "" "int va;" \ "" "" \ "VA & operator=\\(VA const ?&\\);${ws}VA\\(VA const ?&\\);${ws}VA\\((void|)\\);" \ "VA & operator=\\(VA const ?&\\);${ws}VA\\(VA const ?&\\);${ws}VA\\((void|)\\);" \ "" # class VB test_one_ptype "ptype VB" "ptype VB" \ "((struct|class) VB \{${ws}public:|struct VB \{)" \ "" \ "" "int vb;" \ "" "int fvb\\((void|)\\);${ws}virtual int vvb\\((void|)\\);" \ "VB & operator=\\(VB const ?&\\);${ws}VB\\(VB const ?&\\);${ws}VB\\((void|)\\);" \ "VB & operator=\\(VB const ?&\\);${ws}VB\\(VB const ?&\\);${ws}VB\\((void|)\\);" \ "" # class V test_one_ptype "ptype V" "ptype V" \ "class V : public VA, public VB \{${ws}public:" \ "" \ "" "int w;" \ "" "int f\\((void|)\\);${ws}virtual int vv\\((void|)\\);" \ "V & operator=\\(V const ?&\\);${ws}V\\(V const ?&\\);${ws}V\\((void|)\\);" \ "V & operator=\\(V const ?&\\);${ws}V\\(V const ?&\\);${ws}V\\((void|)\\);" \ "" # class A test_one_ptype "ptype A" "ptype A" \ "class A : public virtual V \{(${ws}private:|)" \ "V \\*(_vb.1V|_vb.V);" \ "" "int a;" \ "public:" "virtual int f\\((void|)\\);" \ "A & operator=\\(A const ?&\\);${ws}A\\(int, A const ?&\\);${ws}A\\(int\\);" \ "A & operator=\\(A const ?&\\);${ws}A\\(A const ?&\\);${ws}A\\((void|)\\);" \ "" # class B test_one_ptype "ptype B" "ptype B" \ "class B : public A \{(${ws}private:|)" \ "V \\*(_vb.1V|_vb.V);" \ "" "int b;" \ "public:" "virtual int f\\((void|)\\);" \ "B & operator=\\(B const ?&\\);${ws}B\\(int, B const ?&\\);${ws}B\\(int\\);" \ "B & operator=\\(B const ?&\\);${ws}B\\(B const ?&\\);${ws}B\\((void|)\\);" \ "" # class C test_one_ptype "ptype C" "ptype C" \ "class C : public virtual V \{(${ws}private:|)" \ "V \\*(_vb.1V|_vb.V);" \ "public:" "int c;" \ "" "" \ "C & operator=\\(C const ?&\\);${ws}C\\(int, C const ?&\\);${ws}C\\(int\\);" \ "C & operator=\\(C const ?&\\);${ws}C\\(C const ?&\\);${ws}C\\((void|)\\);" \ "" # class AD test_one_ptype "ptype AD" "ptype AD" \ "((struct|class) AD \{${ws}public:|struct AD \{)" \ "" \ "" "" \ "" "virtual int vg\\((void|)\\);" \ "AD & operator=\\(AD const ?&\\);${ws}AD\\(AD const ?&\\);${ws}AD\\((void|)\\);" \ "AD & operator=\\(AD const ?&\\);${ws}AD\\(AD const ?&\\);${ws}AD\\((void|)\\);" \ "" # class D test_one_ptype "ptype D" "ptype D" \ "class D : public AD, public virtual V \{(${ws}private:|)" \ "V \\*(_vb.1V|_vb.V);" \ "public:" "int d;" \ "" "static void s\\((void|)\\);${ws}virtual int vg\\((void|)\\);${ws}virtual int vd\\((void|)\\);${ws}int fd\\((void|)\\);" \ "D & operator=\\(D const ?&\\);${ws}D\\(int, D const ?&\\);${ws}D\\(int\\);" \ "D & operator=\\(D const ?&\\);${ws}D\\(D const ?&\\);${ws}D\\((void|)\\);" \ "" # class E # TODO: E does not show a vbptr for V.
