development so there
is no reason not to keep it locally. Implemented a basic disassembler which can be used
to scan bytecode for interesting conditions. This should be pretty easy to add to for
things other than exploitability if there is a desire. This also adds several tests to
the windows exploitability ranking code to take advantage of the disassembler for x86
code.

This patch avoids unnecessary use of the <cfoo> headers in files that don't
actually use the identifiers they declare in the std:: namespace.
It also changes some files to better conform with the "Names and Order of
Includes" rules in the Google C++ Style Guide.

The google_breakpad::TestAssembler classes are used in both the processor's
and the Linux dumper's test suites, and will soon be used in the Mac
dumper's tests as well. This patch moves their source files from
src/processor to src/common.

When building with G++ 4.1.2, src/processor/cfi_frame_info.cc fails to
build with the error below. G++ 4.2.1 and later do not seem to report this
problem.
This patch works around the problem by casting stream.tellp() to
std::streamoff before doing the comparison.

pdb filenames in crash reports may contain embedded newlines. When
minidump-stackwalk prints these lines, it ends up with:
Module|olek8r4u.dll|6.0.6000.16386|\\xc2\\xeb\\x17\\x04J\\xb6:\\xbaT\\xf3\\xef\\xe8Y\\x90\\x86\\xaa\\xe5\\x16n\\xb1\\x80\\x85\\t\\x12!\\x16\\x0f\\x98\\xf8\\x89\\x16"\\x96\\xd4\\x84\\x88\\xea\\xe3\\r\\r\\x1b\\xca\\x85*^h\\xf5\\xdc\n\\xd9\\xf4}j\\x1d7\\xe39o\\x1f\\xc5\\xc4\\xa6x\\x8ba\\xe8\\xd6K\\x89H\\xe1\\xff\\xe7\\xf5\\xf0Y\\xfd\\xf5\\xdbu\\x0c\\x07\\x86\\xed|29E0B04FCCBE47EB86A6C819E8B89D051|0x00f60000|0x00ff2fff|0\n
Which has an embedded newline and the machine parser can't handle it. This
patch just strips the embedded newline, just as we strip embedded |
separator characters.

frames other than the youngest. Unit tests are included.

This patch allows the Breakpad minidump processor to use data from
STACK CFI records to generate stack traces for the ARM processor.
In the symbol dumper, we need a table mapping DWARF CFI register
numbers to their names: STACK CFI records refer to registers by name.
In the processor, we expand StackwalkerARM::GetCallerFrame to see if
there are STACK CFI records covering the callee, and then use those to
recover the caller's register values.
There's no good reason the ARM walker couldn't use the SimpleCFIWalker
interface declared in cfi_frame_info.h. Unfortunately, that interface
assumes that one can map register names to member pointers of the raw
context type, while MDRawContextARM uses an array to hold the
registers' values: C++ pointer-to-member types can't refer to elements
of member arrays. So we have to write out SimpleCFIWalker::FindCallerRegisters
in StackwalkerARM::GetCallerFrame.
We define enum MDARMRegisterNumbers in minidump_cpu_arm.h, for
convenience in referring to certain ARM registers with dedicated
purposes, like the stack pointer and the PC.
We define validity flags in StackFrameARM for all the registers, since
CFI could theoretically recover any of them. In the same vein, we
expand minidump_stackwalk.cc to print the values of all valid
callee-saves registers in the context --- and use the proper names for
special-purpose registers.
We provide unit tests that give full code and branch coverage (with
minor exceptions). We add a testing interface to StackwalkerARM that
allows us to create context frames that lack some register values.

Add a CFIFrameInfo class (named for symmetry with WindowsFrameInfo) to
represent the set of STACK CFI rules in effect at a given instruction,
and apply them to a set of register values. Provide a SimpleCFIWalker
class template, to allow the essential CFI code to be shared amongst
the different architectures.
Teach BasicSourceLineResolver to partially parse 'STACK CFI' records,
and produce the set of rules in effect at a given instruction on
demand, by combining the initial rule set and the appropriate rule
deltas in a CFIFrameInfo object.
Adapt StackwalkerX86 and StackFrameX86 to retrieve, store, and apply
CFI stack walking information.
Add validity flags for all the general-purpose registers to
StackFrameX86::ContextValidity.

Issue 53001 (http://breakpad.appspot.com/53001) defines the
TestAssembler classes; those, along with a new set of mock classes
defined in stackwalker_unittest_utils.h, make it possible for us to
actually do proper unit testing of a stack walker. These tests get us
full code coverage for stackwalker_x86.cc.

This also adds two new test utility class groups, TestAssembler and
SynthMinidump. These are overkill for what I'm doing with them here
(and may simply be overkill, period), but they make it easy to write
unit tests for code that works on binary files or raw memory contents
in a cross-platform way. I'm planning to use them for the DWARF CFI
unwinding tests and the DWARF CFI parser tests.
