Add gdb scripts for memquery and drsymload (#4505) Adds two gdb python scripts I've developed that may be useful to others: 1) drsymload: loads DR symbols regardless of gdb's current state, which may include having DR symbols at the wrong address. It does this by reading /proc/self/maps and running objdump on libdynamorio.so. Ideally this would be integrated into a revived libdynamorio.so-gdb.py: that's part of #2100. 2) memquery: prints the /proc/self/maps line for a given address. I'm still shocked gdb doesn't provide such a command natively. Issue: #2100
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.
Tools built on DynamoRIO and provided in our 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 under a BSD license.
