+// Code for reading in ELF files.
+//
+// For information on the ELF format, see
+// http://www.x86.org/ftp/manuals/tools/elf.pdf
+//
+// I also liked:
+// http://www.caldera.com/developers/gabi/1998-04-29/contents.html
+//
+// A note about types: When dealing with the file format, we use types
+// like Elf32_Word, but in the public interfaces we treat all
+// addresses as uint64. As a result, we should be able to symbolize
+// 64-bit binaries from a 32-bit process (which we don't do,
+// anyway). size_t should therefore be avoided, except where required
+// by things like mmap().
+//
+// Although most of this code can deal with arbitrary ELF files of
+// either word size, the public ElfReader interface only examines
+// files loaded into the current address space, which must all match
+// __WORDSIZE. This code cannot handle ELF files with a non-native
+// byte ordering.
+//
+// TODO(chatham): It would be nice if we could accomplish this task
+// without using malloc(), so we could use it as the process is dying.

+
+// Key Abstractions
+// ----------------
+//
+// This file declares multiple classes and protocols that are used by the
+// GTMLogger logging system. 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).

+// test-assembler.h: interface to class for building complex binary streams.
+
+// To test the Breakpad symbol dumper and processor thoroughly, for
+// all combinations of host system and minidump processor
+// architecture, we need to be able to easily generate complex test
+// data like debugging information and minidump files.
+//
+// For example, if we want our unit tests to provide full code
+// coverage for stack walking, it may be difficult to persuade the
+// compiler to generate every possible sort of stack walking
+// information that we want to support; there are probably DWARF CFI
+// opcodes that GCC never emits. Similarly, if we want to test our

+// A Label represents a value not yet known that we need to store in a
+// section. As long as all the labels a section refers to are defined
+// by the time we retrieve its contents as bytes, we can use undefined
+// labels freely in that section's construction.
+//
+// A label can be in one of three states:
+// - undefined,
+// - defined as the sum of some other label and a constant, or
+// - a constant.
+//
+// A label's value never changes, but it can accumulate constraints.
+// Adding labels and integers is permitted, and yields a label.
+// Subtracting a constant from a label is permitted, and also yields a
+// label. Subtracting two labels that have some relationship to each
+// other is permitted, and yields a constant.
+//
+// For example:
+//
+// Label a; // a's value is undefined
+// Label b; // b's value is undefined
+// {
+// Label c = a + 4; // okay, even though a's value is unknown
+// b = c + 4; // also okay; b is now a+8
+// }
+// Label d = b - 2; // okay; d == a+6, even though c is gone
+// d.Value(); // error: d's value is not yet known
+// d - a; // is 6, even though their values are not known
+// a = 12; // now b == 20, and d == 18
+// d.Value(); // 18: no longer an error
+// b.Value(); // 20
+// d = 10; // error: d is already defined.
+//
+// Label objects' lifetimes are unconstrained: notice that, in the
+// above example, even though a and b are only related through c, and
+// c goes out of scope, the assignment to a sets b's value as well. In
+// particular, it's not necessary to ensure that a Label lives beyond

+// Although the relations between labels are supposed to behave
+// symmetrically --- that is, 'a = b' should put a and b in
+// indistinguishable states --- there's a distinction made internally
+// between the target (a) and the source (b).
+//
+// So there are five test axes to cover:
+//
+// - Do we construct the chain with assignment ("Assign") or with constructors
+// ("Construct")?
+//
+// - Do we set the value of the label at the start of the chain
+// ("Start") or the label at the end ("End")?
+//
+// - Are we testing the propagation of a relationship between variable
+// values ("Relation"), or the propagation of a known constant value
+// ("Value")?
+//
+// - Do we set the value before building the chain ("Before") or after
+// the chain has been built ("After")?
+//
+// - Do we add new relationships to the end of the existing chain
+// ("Forward") or to the beginning ("Backward")?
+//
+// Of course, "Construct" and "Backward" can't be combined, which
+// eliminates eight combinations, and "Construct", "End", and "Before"
+// can't be combined, which eliminates two more, so there are are 22
+// combinations, not 32.

+// This contains a suite of tools for transforming symbol information when
+// when that information has been extracted from a PDB containing OMAP
+// information.
+
+// OMAP information is a lightweight description of a mapping between two
+// address spaces. It consists of two streams, each of them a vector 2-tuples.
+// The OMAPTO stream contains tuples of the form
+//
+// (RVA in transformed image, RVA in original image)
+//
+// while the OMAPFROM stream contains tuples of the form
+//
+// (RVA in original image, RVA in transformed image)
+//
+// The entries in each vector are sorted by the first value of the tuple, and
+// the lengths associated with a mapping are implicit as the distance between
+// two successive addresses in the vector.
+
+// Consider a trivial 10-byte function described by the following symbol:
+//
+// Function: RVA 0x00001000, length 10, "foo"
+//
+// Now consider the same function, but with 5-bytes of instrumentation injected
+// at offset 5. The OMAP streams describing this would look like:
+//
+// OMAPTO : [ [0x00001000, 0x00001000],
+// [0x00001005, 0xFFFFFFFF],
+// [0x0000100a, 0x00001005] ]
+// OMAPFROM: [ [0x00001000, 0x00001000],
+// [0x00001005, 0x0000100a] ]
+//
+// In this case the injected code has been marked as not originating in the
+// source image, and thus it will have no symbol information at all. However,
+// the injected code may also be associated with an original address range;
+// for example, when prepending instrumentation to a basic block the
+// instrumentation can be labelled as originating from the same source BB such
+// that symbol resolution will still find the appropriate source code line
+// number. In this case the OMAP stream would look like:
+//
+// OMAPTO : [ [0x00001000, 0x00001000],
+// [0x00001005, 0x00001005],
+// [0x0000100a, 0x00001005] ]
+// OMAPFROM: [ [0x00001000, 0x00001000],
+// [0x00001005, 0x0000100a] ]
+//
+// Suppose we asked DIA to lookup the symbol at location 0x0000100a of the
+// instrumented image. It would first run this through the OMAPTO table and
+// translate that address to 0x00001005. It would then lookup the symbol
+// at that address and return the symbol for the function "foo". 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. Symbol resolution works (starting from an instrumented address,
+// mapping to an original address, and looking up a symbol), but the symbol
+// metadata is incorrect.
+//
+// If we dump the symbols using DIA they will have their addresses
+// appropriately transformed and reflect positions in the instrumented image.
+// However, if we try to do a lookup using those symbols resolution can fail.
+// For example, the address 0x0000100a will not map to the symbol for "foo",
+// because DIA tells us it is at location 0x00001000 (correct) with length
+// 10 (incorrect). 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. This requires the rest of the toolchain to be aware of
+// OMAP information and to use it when present prior to performing lookup. The
+// other option is to properly transform the symbols (updating length as well as
+// position) so that resolution will work as expected for translated addresses.
+// This is transparent to the rest of the toolchain.
