For now, I ignore it, and allow either 97# "class" or "struct" in the output, as long as the access specifiers all 98# work out okay. 99# 100# IN_TAG is the class tag or structure tag. 101# 102# IN_CLASS_TABLE is a list of class information. Each entry contains a 103# keyword and some values. The keywords and their values are: 104# 105# { base "base-declaration" } 106# 107# the class has a base with the given declaration. 108# 109# { vbase "name" } 110# 111# the class has a virtual base pointer with the given name. this 112# is for gcc 2.95.3, which emits ptype entries for the virtual base 113# pointers. the vbase list includes both indirect and direct 114# virtual base classes (indeed, a virtual base is usually 115# indirect), so this information cannot be derived from the base 116# declarations. 117# 118# { field "access" "declaration" } 119# 120# the class has a data field with the given access type and the 121# given declaration. 122# 123# { method "access" "declaration" } 124# 125# the class has a member function with the given access type 126# and the given declaration. 127# 128# { typedef "access" "declaration" } 129# 130# the class has a typedef with the given access type and the 131# given declaration. 132# 133# { type "access" "key" "name" children } 134# 135# The class has a nested type definition with the given ACCESS. 136# KEY is the keyword of the nested type ("enum", "union", "struct", 137# "class"). 138# NAME is the (tag) name of the type. 139# CHILDREN is a list of the type's children. For struct and union keys, 140# this is simply the same type of list that is normally passed to 141# this procedure. For enums the list of children should be the 142# defined enumerators. For unions it is a list of declarations. 143# NOTE: The enum key will add a regexp to handle optional storage 144# class specifiers (": unsigned int", e.g.). The caller need not 145# specify this. 146# 147# If you test the same class declaration more than once, you can specify 148# IN_CLASS_TABLE as "ibid". "ibid" means: look for a previous class 149# table that had the same IN_KEY and IN_TAG, and re-use that table. 150# 151# IN_TAIL is the expected text after the close brace, specifically the "*" 152# in "struct { ... } *". This is an optional parameter. The default 153# value is "", for no tail. 154# 155# IN_ERRATA_TABLE is a list of errata entries. See cp_check_errata for the 156# format of the errata table. Note: the errata entries are not subject to 157# demangler syntax adjustment, so you have to make a bigger table 158# with lines for each output variation. 159# 160# IN_PTYPE_ARG are arguments to pass to ptype. The default is "/r". 161# 162# RECURSIVE_QID is used internally to call this procedure recursively 163# when, e.g., testing nested type definitions. The "ptype" command will 164# not be sent to GDB and the lines in the queue given by this argument will 165# be used instead. 166# 167# gdb can vary the output of ptype in several ways: 168# 169# . CLASS/STRUCT 170# 171# The output can start with either "class" or "struct", depending on 172# what the symbol table reader in gdb decides. This is usually 173# unrelated to the original source code. 174# 175# dwarf-2 debug info distinguishes class/struct, but gdb ignores it 176# stabs+ debug info does not distinguish class/struct 177# hp debug info distinguishes class/struct, and gdb honors it 178# 179# I tried to accommodate this with regular expressions such as 180# "((class|struct) A \{ public:|struct A \{)", but that turns into a 181# hairy mess because of optional private virtual base pointers and 182# optional public synthetic operators. This is the big reason I gave 183# up on regular expressions and started parsing the output. 184# 185# . REDUNDANT ACCESS SPECIFIER 186# 187# In "class { private: ... }" or "struct { public: ... }", gdb might 188# or might not emit a redundant initial access specifier, depending 189# on the gcc version. 190# 191# . VIRTUAL BASE POINTERS 192# 193# If a class has virtual bases, either direct or indirect, the class 194# will have virtual base pointers. With gcc 2.95.3, gdb prints lines 195# for these virtual base pointers. This does not happen with gcc 196# 3.3.4, gcc 3.4.1, or hp acc A.03.45. 197# 198# I accept these lines. These lines are optional; but if I see one of 199# these lines, then I expect to see all of them. 200# 201# Note: drow considers printing these lines to be a bug in gdb. 202# 203# . SYNTHETIC METHODS 204# 205# A C++ compiler may synthesize some methods: an assignment 206# operator, a copy constructor, a constructor, and a destructor. The 207# compiler might include debug information for these methods. 208# 209# dwarf-2 gdb does not show these methods 210# stabs+ gdb shows these methods 211# hp gdb does not show these methods 212# 213# I accept these methods. These lines are optional, and any or 214# all of them might appear, mixed in anywhere in the regular methods. 215# 216# With gcc v2, the synthetic copy-ctor and ctor have an additional 217# "int" parameter at the beginning, the "in-charge" flag. 218# 219# .
