i#4865 emul: Refactor drmgr callback list management (#4945) The drmgr_bb_cb_add() and drmgr_bb_cb_remove() functions had become unwieldy over time, with very long lists of parameters and complex conditionals. This makes it difficult to add new callbacks. Here we refactor them to take in helpers to set key fields while sharing all of the other code. A new has_pair field is also added. This fixes a bug where drmgr_register_opcode_instrumentation_event() incorrectly increased the pair count. Issue: #4865
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.
DynamoRIO is the basis for some well-known external tools:
Tools built on DynamoRIO and available in the release package include:
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.
DynamoRIO is available free of charge as a binary package for both Windows and Linux. DynamoRIO's source code is available primarily under a BSD license.
