It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC to any special C compiler that is needed for +# multi-threaded programs (defaults to the value of CC otherwise). (This +# is necessary on AIX to use the special cc_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also link it with them as well. e.g. you should link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threads programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name +# (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository. We are also +# grateful for the helpful feedback of numerous users. +# +# LICENSE +# +# Copyright (c) 2008 Steven G.

It would be nice to be able to have separate +// handler classes for separate kinds of DIEs, each with the members +// appropriate to its role, instead of having one handler class that +// needs to hold data for every DIE type. +// +// - There should be a separate instance of the appropriate handler +// class for each DIE, instead of a single object with tables +// tracking all the dies in the compilation unit. +// +// - It's not convenient to take some action after all a DIE's +// attributes have been seen, but before visiting any of its +// children.

These handler classes must inherit from +// DIEHandler. Thus: +// +// class My_DW_TAG_X_Handler: public DIEHandler { ... }; +// class My_DW_TAG_Y_Handler: public DIEHandler { ... }; +// +// DIEHandler subclasses needn't correspond exactly to single DIE +// types, as shown here; the point is that you can have several +// different classes appropriate to different kinds of DIEs. +// +// - In particular, define a handler class for the compilation +// unit's root DIE, that inherits from RootDIEHandler: +// +// class My_DW_TAG_compile_unit_Handler: public RootDIEHandler { ... }; +// +// RootDIEHandler inherits from DIEHandler, adding a few additional +// member functions for examining the compilation unit as a whole, +// and other quirks of rootness. +// +// - Then, create a DIEDispatcher instance, passing it an instance of +// your root DIE handler class, and use that DIEDispatcher as the +// dwarf2reader::CompilationUnit's handler: +// +// My_DW_TAG_compile_unit_Handler root_die_handler(...); +// DIEDispatcher die_dispatcher(&root_die_handler); +// CompilationUnit reader(sections, offset, bytereader, &die_dispatcher); +// +// Here, 'die_dispatcher' acts as a shim between 'reader' and the +// various DIE-specific handlers you have defined. +// +// - When you call reader.Start(), die_dispatcher behaves as follows, +// starting with your root die handler and the compilation unit's +// root DIE: +// +// - It calls the handler's ProcessAttributeX member functions for +// each of the DIE's attributes. +// +// - It calls the handler's EndAttributes member function. This +// should return true if any of the DIE's children should be +// visited, in which case: +// +// - For each of the DIE's children, die_dispatcher calls the +// DIE's handler's FindChildHandler member function. If that +// returns a pointer to a DIEHandler instance, then +// die_dispatcher uses that handler to process the child, using +// this procedure recursively. Alternatively, if +// FindChildHandler returns NULL, die_dispatcher ignores that +// child and its descendants. +// +// - When die_dispatcher has finished processing all the DIE's +// children, it invokes the handler's Finish() member function, +// and destroys the handler. (As a special case, it doesn't +// destroy the root DIE handler.) +// +// This allows the code for handling a particular kind of DIE to be +// gathered together in a single class, makes it easy to skip all the +// children or individual children of a particular DIE, and provides +// appropriate parental context for each die. + +#ifndef COMMON_DWARF_DWARF2DIEHANDLER_H__ +#define COMMON_DWARF_DWARF2DIEHANDLER_H__ + +#include + +#include "common/dwarf/types.h" +#include "common/dwarf/dwarf2enums.h" +#include "common/dwarf/dwarf2reader.h" + +namespace dwarf2reader { + +// A base class for handlers for specific DIE types.

Thus, the row for func+0 +// describes the state before we allocate the stack frame. In the +// next row, the formula for computing the CFA has changed, +// reflecting that allocation. +// +// - The other entries are written in terms of the CFA; this allows +// them to remain unchanged as the stack pointer gets bumped around. +// For example, the rule for recovering the return address (the "ra" +// column) remains unchanged throughout the function, even as the +// stack pointer takes on three different offsets from the return +// address. +// +// - Although we haven't shown it, most calling conventions designate +// "callee-saves" and "caller-saves" registers. The callee must +// preserve the values of callee-saves registers; if it uses them, +// it must save their original values somewhere, and restore them +// before it returns. In contrast, the callee is free to trash +// caller-saves registers; if the callee uses these, it will +// probably not bother to save them anywhere, and the CFI will +// probably mark their values as "unrecoverable". +// +// (However, since the caller cannot assume the callee was going to +// save them, caller-saves registers are probably dead in the caller +// anyway, so compilers usually don't generate CFA for caller-saves +// registers.) +// +// - Exactly where the CFA points is a matter of convention that +// depends on the architecture and ABI in use. In the example, the +// CFA is the value the stack pointer had upon entry to the +// function, pointing at the saved return address. But on the x86, +// the call frame information generated by GCC follows the +// convention that the CFA is the address *after* the saved return +// address. +// +// But by definition, the CFA remains constant throughout the +// lifetime of the frame. This makes it a useful value for other +// columns to refer to. It is also gives debuggers a useful handle +// for identifying a frame. +// +// If you look at the table above, you'll notice that a given entry is +// often the same as the one immediately above it: most instructions +// change only one or two aspects of the stack frame, if they affect +// it at all. The DWARF format takes advantage of this fact, and +// reduces the size of the data by mentioning only the addresses and +// columns at which changes take place. So for the above, DWARF CFI +// data would only actually mention the following: +// +// insn cfa r0 r1 ... ra +// ======================================= +// func+0: sp cfa[0] +// func+1: sp+16 +// func+2: cfa[-4] +// func+11: sp+20 +// func+21: r0 +// func+22: sp +// +// In fact, this is the way the parser reports CFI to the consumer: as +// a series of statements of the form, "At address X, column Y changed +// to Z," and related conventions for describing the initial state. +// +// Naturally, it would be impractical to have to scan the entire +// program's CFI, noting changes as we go, just to recover the +// unwinding rules in effect at one particular instruction. To avoid +// this, CFI data is grouped into "entries", each of which covers a +// specified range of addresses and begins with a complete statement +// of the rules for all recoverable registers at that starting +// address. Each entry typically covers a single function. +// +// Thus, to compute the contents of a given row of the table --- that +// is, rules for recovering the CFA, RA, and registers at a given +// instruction --- the consumer should find the entry that covers that +// instruction's address, start with the initial state supplied at the +// beginning of the entry, and work forward until it has processed all +// the changes up to and including those for the present instruction. +// +// There are seven kinds of rules that can appear in an entry of the +// table: +// +// - "undefined": The given register is not preserved by the callee; +// its value cannot be recovered. +// +// - "same value": This register has the same value it did in the callee. +// +// - offset(N): The register is saved at offset N from the CFA. +// +// - val_offset(N): The value the register had in the caller is the +// CFA plus offset N.

Streams must appear in +// the stream directory; memory ranges should be listed in the +// memory list; threads should be placed in the thread list; and so +// on. +// +// By convention, Section subclass constructors that take references +// to other Sections do not take care of 'Add'ing their arguments to +// the dump. For example, although the Thread constructor takes +// references to a Memory and a Context, it does not add them to the +// dump on the caller's behalf. Rather, the caller is responsible for +// 'Add'ing every section they create.
