# 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_COMMAND and IN_TESTNAME are the command and testname for
# gdb_test_multiple. If IN_TESTNAME is the empty string, then it
# defaults to IN_COMMAND.
#
# 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.
#
# 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.
#
# 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.
#
# TESTED WITH
#
# gcc 2.95.3 -gdwarf-2

# TCL/EXPECT WART ALERT
# Expect does something very strange when it receives a single braced
# argument. It splits it along word separators and performs substitutions.
# This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is
# evaluated as "\[ab\]". But that's not how TCL normally works; inside a
# double-quoted list item, "\[ab\]" is just a long way of representing
# "[ab]", because the backslashes will be removed by lindex.
 
# Unfortunately, there appears to be no easy way to duplicate the splitting
# that expect will do from within TCL. And many places make use of the
# "\[0-9\]" construct, so we need to support that; and some places make use
# of the "[func]" construct, so we need to support that too. In order to
# get this right we have to substitute quoted list elements differently
# from braced list elements.
 
# We do this roughly the same way that Expect does it. We have to use two
# lists, because if we leave unquoted newlines in the argument to uplevel
# they'll be treated as command separators, and if we escape newlines
# we mangle newlines inside of command blocks. This assumes that the
# input doesn't contain a pattern which contains actual embedded newlines
# at this point!

# Single Unix Spec v3 says that "-E -o ..." together are not
# specified. And in fact, the native compiler on hp-ux 11 (among
# others) does not work with "-E -o ...". Most targets used to do
# this, and it mostly worked, because it works with gcc.
#
# [ catch "exec $compiler -E $ifile > $binfile.ci" exec_output ]
# source $binfile.ci
#
# This avoids the problem with -E and -o together. This almost works
# if the build machine is the same as the host machine, which is
# usually true of the targets which are not gcc. But this code does
# not figure which compiler to call, and it always ends up using the C
# compiler. Not good for setting hp_aCC_compiler. Targets
# hppa*-*-hpux* and mips*-*-irix* used to do this.

# gdb_get_line_number TEXT [FILE]
#
# Search the source file FILE, and return the line number of the
# first line containing TEXT. If no match is found, return -1.
#
# TEXT is a string literal, not a regular expression.
#
# The default value of FILE is "$srcdir/$subdir/$srcfile". If FILE is
# specified, and does not start with "/", then it is assumed to be in
# "$srcdir/$subdir". This is awkward, and can be fixed in the future,
# by changing the callers and the interface at the same time.
# In particular: gdb.base/break.exp, gdb.base/condbreak.exp,
# gdb.base/ena-dis-br.exp.
#
# Use this function to keep your test scripts independent of the
# exact line numbering of the source file. Don't write:
#
# send_gdb "break 20"
#
# This means that if anyone ever edits your test's source file,
# your test could break. Instead, put a comment like this on the
# source file line you want to break at:
#
# /* breakpoint spot: frotz.exp: test name */
#
# and then write, in your test script (which we assume is named
# frotz.exp):
#
# send_gdb "break [gdb_get_line_number "frotz.exp: test name"]\n"
#
# (Yes, Tcl knows how to handle the nested quotes and brackets.
# Try this:
# $ tclsh
# % puts "foo [lindex "bar baz" 1]"
# foo baz
# %
# Tcl is quite clever, for a little stringy language.)
#
# ===
#
# The previous implementation of this procedure used the gdb search command.
# This version is different:
#
# . It works with MI, and it also works when gdb is not running.
#
# . It operates on the build machine, not the host machine.
#
# . For now, this implementation fakes a current directory of
# $srcdir/$subdir to be compatible with the old implementation.
# This will go away eventually and some callers will need to
# be changed.
#
# . The TEXT argument is literal text and matches literally,
# not a regular expression as it was before.
#
# . State changes in gdb, such as changing the current file
# and setting $_, no longer happen.
#
# After a bit of time we can forget about the differences from the
# old implementation.
