# Test ptype of a class.
#
# Different C++ compilers produce different output.  To accommodate all
# the variations listed below, I read the output of "ptype" and process
# each line, matching it to the class description given in the
# parameters.
#
# IN_EXP is the expression to use; the appropriate "ptype" invocation
# is prepended to it.  IN_TESTNAME is the testname for
# gdb_test_multiple.  If IN_TESTNAME is the empty string, then it
# defaults to "ptype IN_EXP".
#
# IN_KEY is "class" or "struct".  For now, I ignore it, and allow either
# "class" or "struct" in the output, as long as the access specifiers all
# work out okay.
#
# IN_TAG is the class tag or structure tag.
#
# IN_CLASS_TABLE is a list of class information.  Each entry contains a
# keyword and some values.  The keywords and their values are:
#
#   { base "base-declaration" }
#
#      the class has a base with the given declaration.
#
#   { vbase "name" }
#
#      the class has a virtual base pointer with the given name.  this
#      is for gcc 2.95.3, which emits ptype entries for the virtual base
#      pointers.  the vbase list includes both indirect and direct
#      virtual base classes (indeed, a virtual base is usually
#      indirect), so this information cannot be derived from the base
#      declarations.
#
#   { field "access" "declaration" }
#
#      the class has a data field with the given access type and the
#      given declaration.
#
#   { method "access" "declaration" }
#
#      the class has a member function with the given access type
#      and the given declaration.
#
#   { typedef "access" "declaration" }
#
#      the class has a typedef with the given access type and the
#      given declaration.
#
# If you test the same class declaration more than once, you can specify
# IN_CLASS_TABLE as "ibid".  "ibid" means: look for a previous class
# table that had the same IN_KEY and IN_TAG, and re-use that table.
#
# IN_TAIL is the expected text after the close brace, specifically the "*"
# in "struct { ... } *".  This is an optional parameter.  The default
# value is "", for no tail.
#
# IN_ERRATA_TABLE is a list of errata entries.  See cp_check_errata for the
# format of the errata table.  Note: the errata entries are not subject to
# demangler syntax adjustment, so you have to make a bigger table
# with lines for each output variation.
# 
# IN_PTYPE_ARG are arguments to pass to ptype.  The default is "/r".
#
# gdb can vary the output of ptype in several ways:
#
# . CLASS/STRUCT
#
#   The output can start with either "class" or "struct", depending on
#   what the symbol table reader in gdb decides.  This is usually
#   unrelated to the original source code.
#
#     dwarf-2  debug info distinguishes class/struct, but gdb ignores it
#     stabs+   debug info does not distinguish class/struct
#     hp       debug info distinguishes class/struct, and gdb honors it
#
#   I tried to accommodate this with regular expressions such as
#   "((class|struct) A \{ public:|struct A \{)", but that turns into a
#   hairy mess because of optional private virtual base pointers and
#   optional public synthetic operators.  This is the big reason I gave
#   up on regular expressions and started parsing the output.
#
# . REDUNDANT ACCESS SPECIFIER
#
#   In "class { private: ... }" or "struct { public: ... }", gdb might
#   or might not emit a redundant initial access specifier, depending
#   on the gcc version.
#
# . VIRTUAL BASE POINTERS
#
#   If a class has virtual bases, either direct or indirect, the class
#   will have virtual base pointers.  With gcc 2.95.3, gdb prints lines
#   for these virtual base pointers.  This does not happen with gcc
#   3.3.4, gcc 3.4.1, or hp acc A.03.45.
#
#   I accept these lines.  These lines are optional; but if I see one of
#   these lines, then I expect to see all of them.
#
#   Note: drow considers printing these lines to be a bug in gdb.
#
# . SYNTHETIC METHODS
#
#   A C++ compiler may synthesize some methods: an assignment
#   operator, a copy constructor, a constructor, and a destructor.  The
#   compiler might include debug information for these methods.
#
#     dwarf-2  gdb does not show these methods
#     stabs+   gdb shows these methods
#     hp       gdb does not show these methods
#
#   I accept these methods.  These lines are optional, and any or
#   all of them might appear, mixed in anywhere in the regular methods.
#
#   With gcc v2, the synthetic copy-ctor and ctor have an additional
#   "int" parameter at the beginning, the "in-charge" flag.
#
# . DEMANGLER SYNTAX VARIATIONS
#
#   Different demanglers produce "int foo(void)" versus "int foo()",
#   "const A&" versus "const A &", and so on.

	98	# IN_ERRATA_TABLE is a list of errata entries. See cp_check_errata for the
	99	# format of the errata table. Note: the errata entries are not subject to
	100	# demangler syntax adjustment, so you have to make a bigger table
	101	# with lines for each output variation.
	102	#
bd69fc68 TT	103	# IN_PTYPE_ARG are arguments to pass to ptype. The default is "/r".
bd69fc68 TT	104	#
78c90502 MC	105	# gdb can vary the output of ptype in several ways:
	106	#
	107	# . CLASS/STRUCT
	108	#
	109	# The output can start with either "class" or "struct", depending on
	110	# what the symbol table reader in gdb decides. This is usually
	111	# unrelated to the original source code.
	112	#
	113	# dwarf-2 debug info distinguishes class/struct, but gdb ignores it
	114	# stabs+ debug info does not distinguish class/struct
	115	# hp debug info distinguishes class/struct, and gdb honors it
	116	#
	117	# I tried to accommodate this with regular expressions such as
	118	# "((class\|struct) A \{ public:\|struct A \{)", but that turns into a
	119	# hairy mess because of optional private virtual base pointers and
	120	# optional public synthetic operators. This is the big reason I gave
	121	# up on regular expressions and started parsing the output.
	122	#
	123	# . REDUNDANT ACCESS SPECIFIER
	124	#
	125	# In "class { private: ... }" or "struct { public: ... }", gdb might
	126	# or might not emit a redundant initial access specifier, depending
	127	# on the gcc version.
	128	#
	129	# . VIRTUAL BASE POINTERS
	130	#
	131	# If a class has virtual bases, either direct or indirect, the class
	132	# will have virtual base pointers. With gcc 2.95.3, gdb prints lines
	133	# for these virtual base pointers. This does not happen with gcc
	134	# 3.3.4, gcc 3.4.1, or hp acc A.03.45.
	135	#
	136	# I accept these lines. These lines are optional; but if I see one of
	137	# these lines, then I expect to see all of them.
	138	#
	139	# Note: drow considers printing these lines to be a bug in gdb.
	140	#
	141	# . SYNTHETIC METHODS
	142	#
	143	# A C++ compiler may synthesize some methods: an assignment
	144	# operator, a copy constructor, a constructor, and a destructor. The
	145	# compiler might include debug information for these methods.
	146	#
	147	# dwarf-2 gdb does not show these methods
	148	# stabs+ gdb shows these methods
	149	# hp gdb does not show these methods
	150	#
	151	# I accept these methods. These lines are optional, and any or
	152	# all of them might appear, mixed in anywhere in the regular methods.
	153	#
	154	# With gcc v2, the synthetic copy-ctor and ctor have an additional
	155	# "int" parameter at the beginning, the "in-charge" flag.
	156	#
	157	# . DEMANGLER SYNTAX VARIATIONS
	158	#
	159	# Different demanglers produce "int foo(void)" versus "int foo()",
	160	# "const A&" versus "const A &", and so on.
	161	#
	162	# TESTED WITH
