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 <stdint.h> - -#include <stack> -#include <string> - -#include "common/dwarf/types.h" -#include "common/dwarf/dwarf2enums.h" -#include "common/dwarf/dwarf2reader.h" -#include "common/using_std_string.h" - -namespace dwarf2reader { - -// A base class for handlers for specific DIE types.

CFI -// describes how to unwind stack frames --- even for functions that do -// not follow fixed conventions for saving registers, whose frame size -// varies as they execute, etc. -// -// CFI describes, at each machine instruction, how to compute the -// stack frame's base address, how to find the return address, and -// where to find the saved values of the caller's registers (if the -// callee has stashed them somewhere to free up the registers for its -// own use). -// -// For example, suppose we have a function whose machine code looks -// like this (imagine an assembly language that looks like C, for a -// machine with 32-bit registers, and a stack that grows towards lower -// addresses): -// -// func: ; entry point; return address at sp -// func+0: sp = sp - 16 ; allocate space for stack frame -// func+1: sp[12] = r0 ; save r0 at sp+12 -// ... ; other code, not frame-related -// func+10: sp -= 4; *sp = x ; push some x on the stack -// ... ; other code, not frame-related -// func+20: r0 = sp[16] ; restore saved r0 -// func+21: sp += 20 ; pop whole stack frame -// func+22: pc = *sp; sp += 4 ; pop return address and jump to it -// -// DWARF CFI is (a very compressed representation of) a table with a -// row for each machine instruction address and a column for each -// register showing how to restore it, if possible. -// -// A special column named "CFA", for "Canonical Frame Address", tells how -// to compute the base address of the frame; registers' entries may -// refer to the CFA in describing where the registers are saved. -// -// Another special column, named "RA", represents the return address. -// -// For example, here is a complete (uncompressed) table describing the -// function above: -// -// insn cfa r0 r1 ... ra -// ======================================= -// func+0: sp cfa[0] -// func+1: sp+16 cfa[0] -// func+2: sp+16 cfa[-4] cfa[0] -// func+11: sp+20 cfa[-4] cfa[0] -// func+21: sp+20 cfa[0] -// func+22: sp cfa[0] -// -// Some things to note here: -// -// - Each row describes the state of affairs *before* executing the -// instruction at the given address. 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. (This is usually only useful for describing -// the stack pointer.) -// -// - register(R): The register's value was saved in another register R. -// -// - expression(E): Evaluating the DWARF expression E using the -// current frame's registers' values yields the address at which the -// register was saved. -// -// - val_expression(E): Evaluating the DWARF expression E using the -// current frame's registers' values yields the value the register -// had in the caller. - -class CallFrameInfo { - public: - // The different kinds of entries one finds in CFI.

The 4 main abstractions used in this file are the -// following: -// -// * logger (GTMLogger) - The main logging class that users interact with. It -// has methods for logging at different levels and uses a log writer, a log -// formatter, and a log filter to get the job done. -// -// * log writer (GTMLogWriter) - Writes a given string to some log file, where -// a "log file" can be a physical file on disk, a POST over HTTP to some URL, -// or even some in-memory structure (e.g., a ring buffer). -// -// * log formatter (GTMLogFormatter) - Given a format string and arguments as -// a va_list, returns a single formatted NSString. A "formatted string" could -// be a string with the date prepended, a string with values in a CSV format, -// or even a string of XML. -// -// * log filter (GTMLogFilter) - Given a formatted log message as an NSString -// and the level at which the message is to be logged, this class will decide -// whether the given message should be logged or not. This is a flexible way -// to filter out messages logged at a certain level, messages that contain -// certain text, or filter nothing out at all. This gives the caller the -// flexibility to dynamically enable debug logging in Release builds. -// -// This file also declares some classes to handle the common log writer, log -// formatter, and log filter cases. Callers can also create their own writers, -// formatters, and filters and they can even build them on top of the ones -// declared here. Keep in mind that your custom writer/formatter/filter may be -// called from multiple threads, so it must be thread-safe. - -#import <Foundation/Foundation.h> -#import "GTMDefines.h" - -// Predeclaration of used protocols that are declared later in this file. -@protocol GTMLogWriter, GTMLogFormatter, GTMLogFilter; - -// GTMLogger -// -// GTMLogger is the primary user-facing class for an object-oriented logging -// system. It is built on the concept of log formatters (GTMLogFormatter), log -// writers (GTMLogWriter), and log filters (GTMLogFilter). When a message is -// sent to a GTMLogger to log a message, the message is formatted using the log -// formatter, then the log filter is consulted to see if the message should be -// logged, and if so, the message is sent to the log writer to be written out. -// -// GTMLogger is intended to be a flexible and thread-safe logging solution. Its -// flexibility comes from the fact that GTMLogger instances can be customized -// with user defined formatters, filters, and writers. And these writers, -// filters, and formatters can be combined, stacked, and customized in arbitrary -// ways to suit the needs at hand. For example, multiple writers can be used at -// the same time, and a GTMLogger instance can even be used as another -// GTMLogger's writer. This allows for arbitrarily deep logging trees. -// -// A standard GTMLogger uses a writer that sends messages to standard out, a -// formatter that smacks a timestamp and a few other bits of interesting -// information on the message, and a filter that filters out debug messages from -// release builds. Using the standard log settings, a log message will look like -// the following: -// -// 2007-12-30 10:29:24.177 myapp[4588/0xa07d0f60] [lvl=1] foo=<Foo: 0x123> -// -// The output contains the date and time of the log message, the name of the -// process followed by its process ID/thread ID, the log level at which the -// message was logged (in the previous example the level was 1: -// kGTMLoggerLevelDebug), and finally, the user-specified log message itself (in -// this case, the log message was @"foo=%@", foo). -// -// Multiple instances of GTMLogger can be created, each configured their own -// way. Though GTMLogger is not a singleton (in the GoF sense), it does provide -// access to a shared (i.e., globally accessible) GTMLogger instance. This makes -// it convenient for all code in a process to use the same GTMLogger instance. -// The shared GTMLogger instance can also be configured in an arbitrary, and -// these configuration changes will affect all code that logs through the shared -// instance. - -// -// Log Levels -// ---------- -// GTMLogger has 3 different log levels: Debug, Info, and Error. GTMLogger -// doesn't take any special action based on the log level; it simply forwards -// this information on to formatters, filters, and writers, each of which may -// optionally take action based on the level. Since log level filtering is -// performed at runtime, log messages are typically not filtered out at compile -// time. The exception to this rule is that calls to the GTMLoggerDebug() macro -// *ARE* filtered out of non-DEBUG builds. This is to be backwards compatible -// with behavior that many developers are currently used to. Note that this -// means that GTMLoggerDebug(@"hi") will be compiled out of Release builds, but -// [[GTMLogger sharedLogger] logDebug:@"hi"] will NOT be compiled out. -// -// Standard loggers are created with the GTMLogLevelFilter log filter, which -// filters out certain log messages based on log level, and some other settings. -// -// In addition to the -logDebug:, -logInfo:, and -logError: methods defined on -// GTMLogger itself, there are also C macros that make usage of the shared -// GTMLogger instance very convenient. These macros are: -// -// GTMLoggerDebug(...) -// GTMLoggerInfo(...) -// GTMLoggerError(...) -// -// Again, a notable feature of these macros is that GTMLogDebug() calls *will be -// compiled out of non-DEBUG builds*. -// -// Standard Loggers -// ---------------- -// GTMLogger has the concept of "standard loggers". A standard logger is simply -// a logger that is pre-configured with some standard/common writer, formatter, -// and filter combination. Standard loggers are created using the creation -// methods beginning with "standard". The alternative to a standard logger is a -// regular logger, which will send messages to stdout, with no special -// formatting, and no filtering. -// -// How do I use GTMLogger? -// ---------------------- -// The typical way you will want to use GTMLogger is to simply use the -// GTMLogger*() macros for logging from code. That way we can easily make -// changes to the GTMLogger class and simply update the macros accordingly. Only -// your application startup code (perhaps, somewhere in main()) should use the -// GTMLogger class directly in order to configure the shared logger, which all -// of the code using the macros will be using. Again, this is just the typical -// situation. -// -// To be complete, there are cases where you may want to use GTMLogger directly, -// or even create separate GTMLogger instances for some reason. That's fine, -// too. -// -// Examples -// -------- -// The following show some common GTMLogger use cases. -// -// 1. You want to log something as simply as possible. Also, this call will only -// appear in debug builds. In non-DEBUG builds it will be completely removed. -// -// GTMLoggerDebug(@"foo = %@", foo); -// -// 2. The previous example is similar to the following. The major difference is -// that the previous call (example 1) will be compiled out of Release builds -// but this statement will not be compiled out. -// -// [[GTMLogger sharedLogger] logDebug:@"foo = %@", foo]; -// -// 3. Send all logging output from the shared logger to a file. We do this by -// creating an NSFileHandle for writing associated with a file, and setting -// that file handle as the logger's writer. -// -// NSFileHandle *f = [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" -// create:YES]; -// [[GTMLogger sharedLogger] setWriter:f]; -// GTMLoggerError(@"hi"); // This will be sent to /tmp/f.log -// -// 4. Create a new GTMLogger that will log to a file. This example differs from -// the previous one because here we create a new GTMLogger that is different -// from the shared logger. -// -// GTMLogger *logger = [GTMLogger standardLoggerWithPath:@"/tmp/temp.log"]; -// [logger logInfo:@"hi temp log file"]; -// -// 5. Create a logger that writes to stdout and does NOT do any formatting to -// the log message. This might be useful, for example, when writing a help -// screen for a command-line tool to standard output. -// -// GTMLogger *logger = [GTMLogger logger]; -// [logger logInfo:@"%@ version 0.1 usage", progName]; -// -// 6. Send log output to stdout AND to a log file. The trick here is that -// NSArrays function as composite log writers, which means when an array is -// set as the log writer, it forwards all logging messages to all of its -// contained GTMLogWriters. -// -// // Create array of GTMLogWriters -// NSArray *writers = [NSArray arrayWithObjects: -// [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" create:YES], -// [NSFileHandle fileHandleWithStandardOutput], nil]; -// -// GTMLogger *logger = [GTMLogger standardLogger]; -// [logger setWriter:writers]; -// [logger logInfo:@"hi"]; // Output goes to stdout and /tmp/f.log -// -// For futher details on log writers, formatters, and filters, see the -// documentation below. -// -// NOTE: GTMLogger is application level logging. By default it does nothing -// with _GTMDevLog/_GTMDevAssert (see GTMDefines.h). An application can choose -// to bridge _GTMDevLog/_GTMDevAssert to GTMLogger by providing macro -// definitions in its prefix header (see GTMDefines.h for how one would do -// that). -// -@interface GTMLogger : NSObject { - @private - id<GTMLogWriter> writer_; - id<GTMLogFormatter> formatter_; - id<GTMLogFilter> filter_; -} - -// -// Accessors for the shared logger instance -// - -// Returns a shared/global standard GTMLogger instance.

This is the -// correct result. -// -// However, if we query DIA for the length and address of the symbol it will -// tell us that it has length 10 and is at RVA 0x00001000. The location is -// correct, but the length doesn't take into account the 5-bytes of injected -// code.

The problem is one of order of operations: in this case -// we're attempting symbol resolution by looking up an instrumented address -// in the table of translated symbols. -// -// One way to handle this is to dump the OMAP information as part of the -// breakpad symbols.
