Use cc to drive cpp and assembler (WIP)

The advantages of letting the compiler drive preprocessing and
assemblying are
 * we do not have to look for cpp or the assembler
 * we can use COMPILE_OPTIONS to pass through options to the assembler
 * we can use Clang's assembler

Issues:
* Clang's preprocessor does not seem to preserve whitespaces as
  required
* Clang's assembler does not support flags we need (maybe there
  are equivalent flags we have to use)
* Clang does not show assembler help with -Wa,-help.

Fixes #1675

About DynamoRIO

DynamoRIO is a runtime code manipulation system that supports code transformations on any part of a program, while it executes. DynamoRIO exports an interface for building dynamic tools for a wide variety of uses: program analysis and understanding, profiling, instrumentation, optimization, translation, etc. Unlike many dynamic tool systems, DynamoRIO is not limited to insertion of callouts/trampolines and allows arbitrary modifications to application instructions via a powerful IA-32/AMD64/ARM/AArch64 instruction manipulation library. DynamoRIO provides efficient, transparent, and comprehensive manipulation of unmodified applications running on stock operating systems (Windows, Linux, or Android) and commodity IA-32, AMD64, ARM, and AArch64 hardware. Mac OSX support is in progress.

Existing DynamoRIO-based tools

Tools built on DynamoRIO and provided in our release package include:

  • The memory debugging tool Dr. Memory
  • The multi-process cache simulator and memory address trace collection and analysis platform drcachesim
  • The legacy processor emulator drcpusim
  • The “strace for Windows” tool drstrace
  • The code coverage tool drcov
  • The library tracing tool drltrace
  • The memory tracing tool memtrace
  • The basic block tracing tool bbbuf
  • The instruction counting tool inscount

Building your own custom tools

DynamoRIO‘s powerful API abstracts away the details of the underlying infrastructure and allows the tool builder to concentrate on analyzing or modifying the application’s runtime code stream. API documentation is included in the release package and can also be browsed online. Slides from our past tutorials are also available.

Downloading DynamoRIO

DynamoRIO is available free of charge as a binary package for both Windows and Linux. DynamoRIO's source code is available under a BSD license.
